83.34 + * A file output stream is an output stream for writing data to a
83.35 + * <code>File</code> or to a <code>FileDescriptor</code>. Whether or not
83.36 + * a file is available or may be created depends upon the underlying
83.37 + * platform. Some platforms, in particular, allow a file to be opened
83.38 + * for writing by only one <tt>FileOutputStream</tt> (or other
83.39 + * file-writing object) at a time. In such situations the constructors in
83.40 + * this class will fail if the file involved is already open.
83.41 + *
83.42 + * <p><code>FileOutputStream</code> is meant for writing streams of raw bytes
83.43 + * such as image data. For writing streams of characters, consider using
83.44 + * <code>FileWriter</code>.

107.32 + * Indicates the kinds of program element to which an annotation type
107.33 + * is applicable. If a Target meta-annotation is not present on an
107.34 + * annotation type declaration, the declared type may be used on any
107.35 + * program element. If such a meta-annotation is present, the compiler
107.36 + * will enforce the specified usage restriction.
107.37 + *
107.38 + * For example, this meta-annotation indicates that the declared type is
107.39 + * itself a meta-annotation type. It can only be used on annotation type
107.40 + * declarations:
107.41 + * <pre>
107.42 + * @Target(ElementType.ANNOTATION_TYPE)
107.43 + * public @interface MetaAnnotationType {
107.44 + * ...
107.45 + * }
107.46 + * </pre>
107.47 + * This meta-annotation indicates that the declared type is intended solely
107.48 + * for use as a member type in complex annotation type declarations. It
107.49 + * cannot be used to annotate anything directly:
107.50 + * <pre>
107.51 + * @Target({})
107.52 + * public @interface MemberType {
107.53 + * ...
107.54 + * }
107.55 + * </pre>
107.56 + * It is a compile-time error for a single ElementType constant to
107.57 + * appear more than once in a Target annotation. For example, the
107.58 + * following meta-annotation is illegal:
107.59 + * <pre>
107.60 + * @Target({ElementType.FIELD, ElementType.METHOD, ElementType.FIELD})
107.61 + * public @interface Bogus {

109.47 + * The abstract class <code>URLConnection</code> is the superclass
109.48 + * of all classes that represent a communications link between the
109.49 + * application and a URL. Instances of this class can be used both to
109.50 + * read from and to write to the resource referenced by the URL. In
109.51 + * general, creating a connection to a URL is a multistep process:
109.52 + * <p>
109.53 + * <center><table border=2 summary="Describes the process of creating a connection to a URL: openConnection() and connect() over time.">
109.54 + * <tr><th><code>openConnection()</code></th>
109.55 + * <th><code>connect()</code></th></tr>
109.56 + * <tr><td>Manipulate parameters that affect the connection to the remote
109.57 + * resource.</td>
109.58 + * <td>Interact with the resource; query header fields and
109.59 + * contents.</td></tr>
109.60 + * </table>
109.61 + * ---------------------------->
109.62 + * <br>time</center>
109.63 + *
109.64 + * <ol>
109.65 + * <li>The connection object is created by invoking the
109.66 + * <code>openConnection</code> method on a URL.
109.67 + * <li>The setup parameters and general request properties are manipulated.
109.68 + * <li>The actual connection to the remote object is made, using the
109.69 + * <code>connect</code> method.
109.70 + * <li>The remote object becomes available. The header fields and the contents
109.71 + * of the remote object can be accessed.
109.72 + * </ol>
109.73 + * <p>
109.74 + * The setup parameters are modified using the following methods:
109.75 + * <ul>
109.76 + * <li><code>setAllowUserInteraction</code>
109.77 + * <li><code>setDoInput</code>
109.78 + * <li><code>setDoOutput</code>
109.79 + * <li><code>setIfModifiedSince</code>
109.80 + * <li><code>setUseCaches</code>
109.81 + * </ul>
109.82 + * <p>
109.83 + * and the general request properties are modified using the method:
109.84 + * <ul>
109.85 + * <li><code>setRequestProperty</code>
109.86 + * </ul>
109.87 + * <p>
109.88 + * Default values for the <code>AllowUserInteraction</code> and
109.89 + * <code>UseCaches</code> parameters can be set using the methods
109.90 + * <code>setDefaultAllowUserInteraction</code> and
109.91 + * <code>setDefaultUseCaches</code>.
109.92 + * <p>
109.93 + * Each of the above <code>set</code> methods has a corresponding
109.94 + * <code>get</code> method to retrieve the value of the parameter or
109.95 + * general request property. The specific parameters and general
109.96 + * request properties that are applicable are protocol specific.
109.97 + * <p>
109.98 + * The following methods are used to access the header fields and
109.99 + * the contents after the connection is made to the remote object:
109.100 + * <ul>
109.101 + * <li><code>getContent</code>
109.102 + * <li><code>getHeaderField</code>
109.103 + * <li><code>getInputStream</code>
109.104 + * <li><code>getOutputStream</code>
109.105 + * </ul>
109.106 + * <p>
109.107 + * Certain header fields are accessed frequently. The methods:
109.108 + * <ul>
109.109 + * <li><code>getContentEncoding</code>
109.110 + * <li><code>getContentLength</code>
109.111 + * <li><code>getContentType</code>
109.112 + * <li><code>getDate</code>
109.113 + * <li><code>getExpiration</code>
109.114 + * <li><code>getLastModifed</code>
109.115 + * </ul>
109.116 + * <p>
109.117 + * provide convenient access to these fields. The
109.118 + * <code>getContentType</code> method is used by the
109.119 + * <code>getContent</code> method to determine the type of the remote
109.120 + * object; subclasses may find it convenient to override the
109.121 + * <code>getContentType</code> method.
109.122 + * <p>
109.123 + * In the common case, all of the pre-connection parameters and
109.124 + * general request properties can be ignored: the pre-connection
109.125 + * parameters and request properties default to sensible values. For
109.126 + * most clients of this interface, there are only two interesting
109.127 + * methods: <code>getInputStream</code> and <code>getContent</code>,
109.128 + * which are mirrored in the <code>URL</code> class by convenience methods.
109.129 + * <p>
109.130 + * More information on the request properties and header fields of
109.131 + * an <code>http</code> connection can be found at:
109.132 + * <blockquote><pre>
109.133 + * <a href="http://www.ietf.org/rfc/rfc2616.txt">http://www.ietf.org/rfc/rfc2616.txt</a>
109.134 + * </pre></blockquote>
109.135 + *
109.136 + * Note about <code>fileNameMap</code>: In versions prior to JDK 1.1.6,
109.137 + * field <code>fileNameMap</code> of <code>URLConnection</code> was public.
109.138 + * In JDK 1.1.6 and later, <code>fileNameMap</code> is private; accessor
109.139 + * and mutator methods {@link #getFileNameMap() getFileNameMap} and
109.140 + * {@link #setFileNameMap(java.net.FileNameMap) setFileNameMap} are added
109.141 + * to access it. This change is also described on the <a href=
109.142 + * "http://java.sun.com/products/jdk/1.2/compatibility.html">
109.143 + * Compatibility</a> page.

109.146 + * <tt>URLConnection</tt> after a request may free network resources associated with this
109.147 + * instance, unless particular protocol specifications specify different behaviours

110.94 + * A charset name must begin with either a letter or a digit. The empty string

110.102 + * <i>aliases</i>. The canonical name is returned by the {@link #name() name} method
110.103 + * of this class. Canonical names are, by convention, usually in upper case.
110.104 + * The aliases of a charset are returned by the {@link #aliases() aliases}
110.105 + * method.

110.107 + * <a name="hn">
110.108 + *
110.109 + * <p> Some charsets have an <i>historical name</i> that is defined for
110.110 + * compatibility with previous versions of the Java platform. A charset's
110.111 + * historical name is either its canonical name or one of its aliases. The
110.112 + * historical name is returned by the <tt>getEncoding()</tt> methods of the
110.113 + * {@link java.io.InputStreamReader#getEncoding InputStreamReader} and {@link

110.167 + * transformation format upon which it is based is specified in
110.168 + * Amendment 2 of ISO 10646-1 and is also described in the <a
110.169 + * href="http://www.unicode.org/unicode/standard/standard.html"><i>Unicode
110.170 + * Standard</i></a>.
110.171 + *
110.172 + * <p> The <tt>UTF-16</tt> charsets are specified by <a
110.173 + * href="http://www.ietf.org/rfc/rfc2781.txt"><i>RFC 2781</i></a>; the
110.174 + * transformation formats upon which they are based are specified in

110.176 + * href="http://www.unicode.org/unicode/standard/standard.html"><i>Unicode
110.177 + * Standard</i></a>.
110.178 + *
110.179 + * <p> The <tt>UTF-16</tt> charsets use sixteen-bit quantities and are
110.180 + * therefore sensitive to byte order. In these encodings the byte order of a
110.181 + * stream may be indicated by an initial <i>byte-order mark</i> represented by
110.182 + * the Unicode character <tt>'\uFEFF'</tt>. Byte-order marks are handled
110.183 + * as follows:
110.184 + *
110.185 + * <ul>
110.186 + *
110.187 + * <li><p> When decoding, the <tt>UTF-16BE</tt> and <tt>UTF-16LE</tt>
110.188 + * charsets interpret the initial byte-order marks as a <small>ZERO-WIDTH
110.189 + * NON-BREAKING SPACE</small>; when encoding, they do not write
110.190 + * byte-order marks. </p></li>
110.191 +
110.192 + *
110.193 + * <li><p> When decoding, the <tt>UTF-16</tt> charset interprets the
110.194 + * byte-order mark at the beginning of the input stream to indicate the
110.195 + * byte-order of the stream but defaults to big-endian if there is no
110.196 + * byte-order mark; when encoding, it uses big-endian byte order and writes
110.197 + * a big-endian byte-order mark. </p></li>
110.198 + *
110.199 + * </ul>
110.200 + *
110.201 + * In any case, byte order marks occuring after the first element of an
110.202 + * input sequence are not omitted since the same code is used to represent
110.203 + * <small>ZERO-WIDTH NON-BREAKING SPACE</small>.
110.204 + *
110.205 + * <p> Every instance of the Java virtual machine has a default charset, which
110.206 + * may or may not be one of the standard charsets. The default charset is
110.207 + * determined during virtual-machine startup and typically depends upon the
110.208 + * locale and charset being used by the underlying operating system. </p>
110.209 + *
110.210 + * <p>The {@link StandardCharsets} class defines constants for each of the
110.211 + * standard charsets.
110.212 + *
110.213 + * <h4>Terminology</h4>
110.214 + *
110.215 + * <p> The name of this class is taken from the terms used in
110.216 + * <a href="http://www.ietf.org/rfc/rfc2278.txt"><i>RFC 2278</i></a>.
110.217 + * In that document a <i>charset</i> is defined as the combination of
110.218 + * one or more coded character sets and a character-encoding scheme.
110.219 + * (This definition is confusing; some other software systems define
110.220 + * <i>charset</i> as a synonym for <i>coded character set</i>.)
110.221 + *
110.222 + * <p> A <i>coded character set</i> is a mapping between a set of abstract
110.223 + * characters and a set of integers. US-ASCII, ISO 8859-1,
110.224 + * JIS X 0201, and Unicode are examples of coded character sets.
110.225 + *
110.226 + * <p> Some standards have defined a <i>character set</i> to be simply a
110.227 + * set of abstract characters without an associated assigned numbering.
110.228 + * An alphabet is an example of such a character set. However, the subtle
110.229 + * distinction between <i>character set</i> and <i>coded character set</i>
110.230 + * is rarely used in practice; the former has become a short form for the
110.231 + * latter, including in the Java API specification.
110.232 + *
110.233 + * <p> A <i>character-encoding scheme</i> is a mapping between one or more
110.234 + * coded character sets and a set of octet (eight-bit byte) sequences.
110.235 + * UTF-8, UTF-16, ISO 2022, and EUC are examples of
110.236 + * character-encoding schemes. Encoding schemes are often associated with
110.237 + * a particular coded character set; UTF-8, for example, is used only to
110.238 + * encode Unicode. Some schemes, however, are associated with multiple
110.239 + * coded character sets; EUC, for example, can be used to encode
110.240 + * characters in a variety of Asian coded character sets.
110.241 + *
110.242 + * <p> When a coded character set is used exclusively with a single
110.243 + * character-encoding scheme then the corresponding charset is usually
110.244 + * named for the coded character set; otherwise a charset is usually named
110.245 + * for the encoding scheme and, possibly, the locale of the coded
110.246 + * character sets that it supports. Hence <tt>US-ASCII</tt> is both the
110.247 + * name of a coded character set and of the charset that encodes it, while
110.248 + * <tt>EUC-JP</tt> is the name of the charset that encodes the
110.249 + * JIS X 0201, JIS X 0208, and JIS X 0212
110.250 + * coded character sets for the Japanese language.
110.251 + *
110.252 + * <p> The native character encoding of the Java programming language is
110.253 + * UTF-16. A charset in the Java platform therefore defines a mapping
110.254 + * between sequences of sixteen-bit UTF-16 code units (that is, sequences
110.255 + * of chars) and sequences of bytes. </p>

111.46 + * <a name="steps">
111.47 + *
111.48 + * <p> The input byte sequence is provided in a byte buffer or a series
111.49 + * of such buffers. The output character sequence is written to a character buffer
111.50 + * or a series of such buffers. A decoder should always be used by making
111.51 + * the following sequence of method invocations, hereinafter referred to as a
111.52 + * <i>decoding operation</i>:
111.53 + *
111.54 + * <ol>
111.55 + *
111.56 + * <li><p> Reset the decoder via the {@link #reset reset} method, unless it
111.57 + * has not been used before; </p></li>
111.58 + *
111.59 + * <li><p> Invoke the {@link #decode decode} method zero or more times, as
111.60 + * long as additional input may be available, passing <tt>false</tt> for the
111.61 + * <tt>endOfInput</tt> argument and filling the input buffer and flushing the
111.62 + * output buffer between invocations; </p></li>
111.63 + *
111.64 + * <li><p> Invoke the {@link #decode decode} method one final time, passing
111.65 + * <tt>true</tt> for the <tt>endOfInput</tt> argument; and then </p></li>
111.66 + *
111.67 + * <li><p> Invoke the {@link #flush flush} method so that the decoder can
111.68 + * flush any internal state to the output buffer. </p></li>
111.69 + *
111.70 + * </ol>
111.71 + *
111.72 + * Each invocation of the {@link #decode decode} method will decode as many
111.73 + * bytes as possible from the input buffer, writing the resulting characters
111.74 + * to the output buffer. The {@link #decode decode} method returns when more
111.75 + * input is required, when there is not enough room in the output buffer, or
111.76 + * when a decoding error has occurred. In each case a {@link CoderResult}
111.77 + * object is returned to describe the reason for termination. An invoker can
111.78 + * examine this object and fill the input buffer, flush the output buffer, or
111.79 + * attempt to recover from a decoding error, as appropriate, and try again.
111.80 + *
111.81 + * <a name="ce">
111.82 + *
111.83 + * <p> There are two general types of decoding errors. If the input byte
111.84 + * sequence is not legal for this charset then the input is considered <i>malformed</i>. If
111.85 + * the input byte sequence is legal but cannot be mapped to a valid
111.86 + * Unicode character then an <i>unmappable character</i> has been encountered.
111.87 + *
111.88 + * <a name="cae">
111.89 + *
111.90 + * <p> How a decoding error is handled depends upon the action requested for
111.91 + * that type of error, which is described by an instance of the {@link
111.92 + * CodingErrorAction} class. The possible error actions are to {@link
111.93 + * CodingErrorAction#IGNORE </code>ignore<code>} the erroneous input, {@link

111.107 + * its value may be changed via the {@link #replaceWith(java.lang.String)
111.108 + * replaceWith} method.
111.109 + *
111.110 + * <p> The default action for malformed-input and unmappable-character errors
111.111 + * is to {@link CodingErrorAction#REPORT </code>report<code>} them. The

112.52 + * <i>encoding operation</i>:
112.53 + *
112.54 + * <ol>
112.55 + *
112.56 + * <li><p> Reset the encoder via the {@link #reset reset} method, unless it

112.58 + *
112.59 + * <li><p> Invoke the {@link #encode encode} method zero or more times, as
112.60 + * long as additional input may be available, passing <tt>false</tt> for the
112.61 + * <tt>endOfInput</tt> argument and filling the input buffer and flushing the
112.62 + * output buffer between invocations; </p></li>
112.63 + *
112.64 + * <li><p> Invoke the {@link #encode encode} method one final time, passing
112.65 + * <tt>true</tt> for the <tt>endOfInput</tt> argument; and then </p></li>
112.66 + *
112.67 + * <li><p> Invoke the {@link #flush flush} method so that the encoder can

112.71 + *
112.72 + * Each invocation of the {@link #encode encode} method will encode as many
112.73 + * characters as possible from the input buffer, writing the resulting bytes
112.74 + * to the output buffer. The {@link #encode encode} method returns when more
112.75 + * input is required, when there is not enough room in the output buffer, or
112.76 + * when an encoding error has occurred. In each case a {@link CoderResult}
112.77 + * object is returned to describe the reason for termination. An invoker can
112.78 + * examine this object and fill the input buffer, flush the output buffer, or
112.79 + * attempt to recover from an encoding error, as appropriate, and try again.
112.80 + *
112.81 + * <a name="ce">
112.82 + *
112.83 + * <p> There are two general types of encoding errors. If the input character
112.84 + * sequence is not a legal sixteen-bit Unicode sequence then the input is considered <i>malformed</i>. If
112.85 + * the input character sequence is legal but cannot be mapped to a valid
112.86 + * byte sequence in the given charset then an <i>unmappable character</i> has been encountered.
112.87 + *
112.88 + * <a name="cae">
112.89 + *
112.90 + * <p> How an encoding error is handled depends upon the action requested for
112.91 + * that type of error, which is described by an instance of the {@link
112.92 + * CodingErrorAction} class. The possible error actions are to {@link
112.93 + * CodingErrorAction#IGNORE </code>ignore<code>} the erroneous input, {@link
112.94 + * CodingErrorAction#REPORT </code>report<code>} the error to the invoker via
112.95 + * the returned {@link CoderResult} object, or {@link CodingErrorAction#REPLACE
112.96 + * </code>replace<code>} the erroneous input with the current value of the
112.97 + * replacement byte array. The replacement
112.98 + *
112.99 +
112.100 + * is initially set to the encoder's default replacement, which often
112.101 + * (but not always) has the initial value <tt>{</tt> <tt>(byte)'?'</tt> <tt>}</tt>;

112.103 +
112.104 +
112.105 +
112.106 + *
112.107 + * its value may be changed via the {@link #replaceWith(byte[])
112.108 + * replaceWith} method.
112.109 + *
112.110 + * <p> The default action for malformed-input and unmappable-character errors
112.111 + * is to {@link CodingErrorAction#REPORT </code>report<code>} them. The
112.112 + * malformed-input error action may be changed via the {@link
112.113 + * #onMalformedInput(CodingErrorAction) onMalformedInput} method; the
112.114 + * unmappable-character action may be changed via the {@link
112.115 + * #onUnmappableCharacter(CodingErrorAction) onUnmappableCharacter} method.
112.116 + *
112.117 + * <p> This class is designed to handle many of the details of the encoding
112.118 + * process, including the implementation of error actions. An encoder for a
112.119 + * specific charset, which is a concrete subclass of this class, need only
112.120 + * implement the abstract {@link #encodeLoop encodeLoop} method, which

115.31 +/**
115.32 + * <p> The AccessController class is used for access control operations
115.33 + * and decisions.
115.34 + *
115.35 + * <p> More specifically, the AccessController class is used for
115.36 + * three purposes:
115.37 + *
115.38 + * <ul>
115.39 + * <li> to decide whether an access to a critical system
115.40 + * resource is to be allowed or denied, based on the security policy
115.41 + * currently in effect,<p>
115.42 + * <li>to mark code as being "privileged", thus affecting subsequent
115.43 + * access determinations, and<p>
115.44 + * <li>to obtain a "snapshot" of the current calling context so
115.45 + * access-control decisions from a different context can be made with
115.46 + * respect to the saved context. </ul>
115.47 + *
115.48 + * <p> The {@link #checkPermission(Permission) checkPermission} method
115.49 + * determines whether the access request indicated by a specified
115.50 + * permission should be granted or denied. A sample call appears
115.51 + * below. In this example, <code>checkPermission</code> will determine
115.52 + * whether or not to grant "read" access to the file named "testFile" in
115.53 + * the "/temp" directory.
115.54 + *
115.55 + * <pre>
115.56 + *
115.57 + * FilePermission perm = new FilePermission("/temp/testFile", "read");
115.58 + * AccessController.checkPermission(perm);
115.59 + *
115.60 + * </pre>
115.61 + *
115.62 + * <p> If a requested access is allowed,
115.63 + * <code>checkPermission</code> returns quietly. If denied, an
115.64 + * AccessControlException is
115.65 + * thrown. AccessControlException can also be thrown if the requested
115.66 + * permission is of an incorrect type or contains an invalid value.
115.67 + * Such information is given whenever possible.
115.68 + *
115.69 + * Suppose the current thread traversed m callers, in the order of caller 1
115.70 + * to caller 2 to caller m. Then caller m invoked the
115.71 + * <code>checkPermission</code> method.
115.72 + * The <code>checkPermission </code>method determines whether access
115.73 + * is granted or denied based on the following algorithm:
115.74 + *
115.75 + * <pre> {@code
115.76 + * for (int i = m; i > 0; i--) {
115.77 + *
115.78 + * if (caller i's domain does not have the permission)
115.79 + * throw AccessControlException
115.80 + *
115.81 + * else if (caller i is marked as privileged) {
115.82 + * if (a context was specified in the call to doPrivileged)
115.83 + * context.checkPermission(permission)
115.84 + * return;
115.85 + * }
115.86 + * };
115.87 + *
115.88 + * // Next, check the context inherited when the thread was created.
115.89 + * // Whenever a new thread is created, the AccessControlContext at
115.90 + * // that time is stored and associated with the new thread, as the
115.91 + * // "inherited" context.
115.92 + *
115.93 + * inheritedContext.checkPermission(permission);
115.94 + * }</pre>
115.95 + *
115.96 + * <p> A caller can be marked as being "privileged"
115.97 + * (see {@link #doPrivileged(PrivilegedAction) doPrivileged} and below).
115.98 + * When making access control decisions, the <code>checkPermission</code>
115.99 + * method stops checking if it reaches a caller that
115.100 + * was marked as "privileged" via a <code>doPrivileged</code>
115.101 + * call without a context argument (see below for information about a
115.102 + * context argument). If that caller's domain has the
115.103 + * specified permission, no further checking is done and
115.104 + * <code>checkPermission</code>
115.105 + * returns quietly, indicating that the requested access is allowed.
115.106 + * If that domain does not have the specified permission, an exception
115.107 + * is thrown, as usual.
115.108 + *
115.109 + * <p> The normal use of the "privileged" feature is as follows. If you
115.110 + * don't need to return a value from within the "privileged" block, do
115.111 + * the following:
115.112 + *
115.113 + * <pre> {@code
115.114 + * somemethod() {
115.115 + * ...normal code here...
115.116 + * AccessController.doPrivileged(new PrivilegedAction<Void>() {
115.117 + * public Void run() {
115.118 + * // privileged code goes here, for example:
115.119 + * System.loadLibrary("awt");
115.120 + * return null; // nothing to return
115.121 + * }
115.122 + * });
115.123 + * ...normal code here...
115.124 + * }}</pre>
115.125 + *
115.126 + * <p>
115.127 + * PrivilegedAction is an interface with a single method, named
115.128 + * <code>run</code>.
115.129 + * The above example shows creation of an implementation
115.130 + * of that interface; a concrete implementation of the
115.131 + * <code>run</code> method is supplied.
115.132 + * When the call to <code>doPrivileged</code> is made, an
115.133 + * instance of the PrivilegedAction implementation is passed
115.134 + * to it. The <code>doPrivileged</code> method calls the
115.135 + * <code>run</code> method from the PrivilegedAction
115.136 + * implementation after enabling privileges, and returns the
115.137 + * <code>run</code> method's return value as the
115.138 + * <code>doPrivileged</code> return value (which is
115.139 + * ignored in this example).
115.140 + *
115.141 + * <p> If you need to return a value, you can do something like the following:
115.142 + *
115.143 + * <pre> {@code
115.144 + * somemethod() {
115.145 + * ...normal code here...
115.146 + * String user = AccessController.doPrivileged(
115.147 + * new PrivilegedAction<String>() {
115.148 + * public String run() {
115.149 + * return System.getProperty("user.name");
115.150 + * }
115.151 + * });
115.152 + * ...normal code here...
115.153 + * }}</pre>
115.154 + *
115.155 + * <p>If the action performed in your <code>run</code> method could
115.156 + * throw a "checked" exception (those listed in the <code>throws</code> clause
115.157 + * of a method), then you need to use the
115.158 + * <code>PrivilegedExceptionAction</code> interface instead of the
115.159 + * <code>PrivilegedAction</code> interface:
115.160 + *
115.161 + * <pre> {@code
115.162 + * somemethod() throws FileNotFoundException {
115.163 + * ...normal code here...
115.164 + * try {
115.165 + * FileInputStream fis = AccessController.doPrivileged(
115.166 + * new PrivilegedExceptionAction<FileInputStream>() {
115.167 + * public FileInputStream run() throws FileNotFoundException {
115.168 + * return new FileInputStream("someFile");
115.169 + * }
115.170 + * });
115.171 + * } catch (PrivilegedActionException e) {
115.172 + * // e.getException() should be an instance of FileNotFoundException,
115.173 + * // as only "checked" exceptions will be "wrapped" in a
115.174 + * // PrivilegedActionException.
115.175 + * throw (FileNotFoundException) e.getException();
115.176 + * }
115.177 + * ...normal code here...
115.178 + * }}</pre>
115.179 + *
115.180 + * <p> Be *very* careful in your use of the "privileged" construct, and
115.181 + * always remember to make the privileged code section as small as possible.
115.182 + *
115.183 + * <p> Note that <code>checkPermission</code> always performs security checks
115.184 + * within the context of the currently executing thread.
115.185 + * Sometimes a security check that should be made within a given context
115.186 + * will actually need to be done from within a
115.187 + * <i>different</i> context (for example, from within a worker thread).
115.188 + * The {@link #getContext() getContext} method and
115.189 + * AccessControlContext class are provided
115.190 + * for this situation. The <code>getContext</code> method takes a "snapshot"
115.191 + * of the current calling context, and places
115.192 + * it in an AccessControlContext object, which it returns. A sample call is
115.193 + * the following:
115.194 + *
115.195 + * <pre>
115.196 + *
115.197 + * AccessControlContext acc = AccessController.getContext()
115.198 + *
115.199 + * </pre>
115.200 + *
115.201 + * <p>
115.202 + * AccessControlContext itself has a <code>checkPermission</code> method
115.203 + * that makes access decisions based on the context <i>it</i> encapsulates,
115.204 + * rather than that of the current execution thread.
115.205 + * Code within a different context can thus call that method on the
115.206 + * previously-saved AccessControlContext object. A sample call is the
115.207 + * following:
115.208 + *
115.209 + * <pre>
115.210 + *
115.211 + * acc.checkPermission(permission)
115.212 + *
115.213 + * </pre>
115.214 + *
115.215 + * <p> There are also times where you don't know a priori which permissions
115.216 + * to check the context against. In these cases you can use the
115.217 + * doPrivileged method that takes a context:
115.218 + *
115.219 + * <pre> {@code
115.220 + * somemethod() {
115.221 + * AccessController.doPrivileged(new PrivilegedAction<Object>() {
115.222 + * public Object run() {
115.223 + * // Code goes here. Any permission checks within this
115.224 + * // run method will require that the intersection of the
115.225 + * // callers protection domain and the snapshot's
115.226 + * // context have the desired permission.
115.227 + * }
115.228 + * }, acc);
115.229 + * ...normal code here...

119.32 +* An Annotation object is used as a wrapper for a text attribute value if
119.33 +* the attribute has annotation characteristics. These characteristics are:
119.34 +* <ul>
119.35 +* <li>The text range that the attribute is applied to is critical to the
119.36 +* semantics of the range. That means, the attribute cannot be applied to subranges
119.37 +* of the text range that it applies to, and, if two adjacent text ranges have
119.38 +* the same value for this attribute, the attribute still cannot be applied to
119.39 +* the combined range as a whole with this value.
119.40 +* <li>The attribute or its value usually do no longer apply if the underlying text is
119.41 +* changed.
119.42 +* </ul>
119.43 +*
119.44 +* An example is grammatical information attached to a sentence:

119.46 +* is the subject, but you cannot say the same about "an", "example", or "exam".

119.49 +*

119.51 +* Wrapping the attribute value into an Annotation object guarantees that
119.52 +* adjacent text runs don't get merged even if the attribute values are equal,

123.47 +/**
123.48 + * This interface defines a protocol for bidirectional iteration over text.
123.49 + * The iterator iterates over a bounded sequence of characters. Characters
123.50 + * are indexed with values beginning with the value returned by getBeginIndex() and
123.51 + * continuing through the value returned by getEndIndex()-1.
123.52 + * <p>
123.53 + * Iterators maintain a current character index, whose valid range is from
123.54 + * getBeginIndex() to getEndIndex(); the value getEndIndex() is included to allow
123.55 + * handling of zero-length text ranges and for historical reasons.
123.56 + * The current index can be retrieved by calling getIndex() and set directly
123.57 + * by calling setIndex(), first(), and last().
123.58 + * <p>
123.59 + * The methods previous() and next() are used for iteration. They return DONE if
123.60 + * they would move outside the range from getBeginIndex() to getEndIndex() -1,
123.61 + * signaling that the iterator has reached the end of the sequence. DONE is
123.62 + * also returned by other methods to indicate that the current index is
123.63 + * outside this range.

125.49 +/**
125.50 + * A <code>ChoiceFormat</code> allows you to attach a format to a range of numbers.
125.51 + * It is generally used in a <code>MessageFormat</code> for handling plurals.
125.52 + * The choice is specified with an ascending list of doubles, where each item
125.53 + * specifies a half-open interval up to the next item:
125.54 + * <blockquote>
125.55 + * <pre>
125.56 + * X matches j if and only if limit[j] <= X < limit[j+1]
125.57 + * </pre>
125.58 + * </blockquote>
125.59 + * If there is no match, then either the first or last index is used, depending
125.60 + * on whether the number (X) is too low or too high. If the limit array is not
125.61 + * in ascending order, the results of formatting will be incorrect. ChoiceFormat
125.62 + * also accepts <code>\u221E</code> as equivalent to infinity(INF).
125.63 + *
125.64 + * <p>
125.65 + * <strong>Note:</strong>
125.66 + * <code>ChoiceFormat</code> differs from the other <code>Format</code>
125.67 + * classes in that you create a <code>ChoiceFormat</code> object with a
125.68 + * constructor (not with a <code>getInstance</code> style factory
125.69 + * method). The factory methods aren't necessary because <code>ChoiceFormat</code>
125.70 + * doesn't require any complex setup for a given locale. In fact,
125.71 + * <code>ChoiceFormat</code> doesn't implement any locale specific behavior.
125.72 + *
125.73 + * <p>
125.74 + * When creating a <code>ChoiceFormat</code>, you must specify an array of formats
125.75 + * and an array of limits. The length of these arrays must be the same.
125.76 + * For example,
125.77 + * <ul>
125.78 + * <li>
125.79 + * <em>limits</em> = {1,2,3,4,5,6,7}<br>
125.80 + * <em>formats</em> = {"Sun","Mon","Tue","Wed","Thur","Fri","Sat"}
125.81 + * <li>
125.82 + * <em>limits</em> = {0, 1, ChoiceFormat.nextDouble(1)}<br>
125.83 + * <em>formats</em> = {"no files", "one file", "many files"}<br>
125.84 + * (<code>nextDouble</code> can be used to get the next higher double, to
125.85 + * make the half-open interval.)
125.86 + * </ul>
125.87 + *
125.88 + * <p>
125.89 + * Here is a simple example that shows formatting and parsing:
125.90 + * <blockquote>
125.91 + * <pre>
125.92 + * double[] limits = {1,2,3,4,5,6,7};
125.93 + * String[] dayOfWeekNames = {"Sun","Mon","Tue","Wed","Thur","Fri","Sat"};
125.94 + * ChoiceFormat form = new ChoiceFormat(limits, dayOfWeekNames);
125.95 + * ParsePosition status = new ParsePosition(0);
125.96 + * for (double i = 0.0; i <= 8.0; ++i) {
125.97 + * status.setIndex(0);
125.98 + * System.out.println(i + " -> " + form.format(i) + " -> "
125.99 + * + form.parse(form.format(i),status));
125.100 + * }
125.101 + * </pre>
125.102 + * </blockquote>
125.103 + * Here is a more complex example, with a pattern format:
125.104 + * <blockquote>
125.105 + * <pre>
125.106 + * double[] filelimits = {0,1,2};
125.107 + * String[] filepart = {"are no files","is one file","are {2} files"};
125.108 + * ChoiceFormat fileform = new ChoiceFormat(filelimits, filepart);
125.109 + * Format[] testFormats = {fileform, null, NumberFormat.getInstance()};
125.110 + * MessageFormat pattform = new MessageFormat("There {0} on {1}");
125.111 + * pattform.setFormats(testFormats);
125.112 + * Object[] testArgs = {null, "ADisk", null};
125.113 + * for (int i = 0; i < 4; ++i) {
125.114 + * testArgs[0] = new Integer(i);
125.115 + * testArgs[2] = testArgs[0];
125.116 + * System.out.println(pattform.format(testArgs));
125.117 + * }
125.118 + * </pre>
125.119 + * </blockquote>
125.120 + * <p>
125.121 + * Specifying a pattern for ChoiceFormat objects is fairly straightforward.
125.122 + * For example:
125.123 + * <blockquote>
125.124 + * <pre>
125.125 + * ChoiceFormat fmt = new ChoiceFormat(
125.126 + * "-1#is negative| 0#is zero or fraction | 1#is one |1.0<is 1+ |2#is two |2<is more than 2.");
125.127 + * System.out.println("Formatter Pattern : " + fmt.toPattern());
125.128 + *
125.129 + * System.out.println("Format with -INF : " + fmt.format(Double.NEGATIVE_INFINITY));
125.130 + * System.out.println("Format with -1.0 : " + fmt.format(-1.0));
125.131 + * System.out.println("Format with 0 : " + fmt.format(0));
125.132 + * System.out.println("Format with 0.9 : " + fmt.format(0.9));
125.133 + * System.out.println("Format with 1.0 : " + fmt.format(1));
125.134 + * System.out.println("Format with 1.5 : " + fmt.format(1.5));
125.135 + * System.out.println("Format with 2 : " + fmt.format(2));
125.136 + * System.out.println("Format with 2.1 : " + fmt.format(2.1));
125.137 + * System.out.println("Format with NaN : " + fmt.format(Double.NaN));
125.138 + * System.out.println("Format with +INF : " + fmt.format(Double.POSITIVE_INFINITY));
125.139 + * </pre>
125.140 + * </blockquote>
125.141 + * And the output result would be like the following:
125.142 + * <blockquote>
125.143 + * <pre>
125.144 + * Format with -INF : is negative
125.145 + * Format with -1.0 : is negative
125.146 + * Format with 0 : is zero or fraction
125.147 + * Format with 0.9 : is zero or fraction
125.148 + * Format with 1.0 : is one
125.149 + * Format with 1.5 : is 1+
125.150 + * Format with 2 : is two
125.151 + * Format with 2.1 : is more than 2.
125.152 + * Format with NaN : is negative
125.153 + * Format with +INF : is more than 2.
125.154 + * </pre>

126.54 + * {@code DateFormat} is an abstract class for date/time formatting subclasses which
126.55 + * formats and parses dates or time in a language-independent manner.
126.56 + * The date/time formatting subclass, such as {@link SimpleDateFormat}, allows for
126.57 + * formatting (i.e., date -> text), parsing (text -> date), and
126.58 + * normalization. The date is represented as a <code>Date</code> object or
126.59 + * as the milliseconds since January 1, 1970, 00:00:00 GMT.
126.60 + *
126.61 + * <p>{@code DateFormat} provides many class methods for obtaining default date/time
126.62 + * formatters based on the default or a given locale and a number of formatting
126.63 + * styles. The formatting styles include {@link #FULL}, {@link #LONG}, {@link #MEDIUM}, and {@link #SHORT}. More
126.64 + * detail and examples of using these styles are provided in the method
126.65 + * descriptions.
126.66 + *
126.67 + * <p>{@code DateFormat} helps you to format and parse dates for any locale.
126.68 + * Your code can be completely independent of the locale conventions for
126.69 + * months, days of the week, or even the calendar format: lunar vs. solar.
126.70 + *
126.71 + * <p>To format a date for the current Locale, use one of the
126.72 + * static factory methods:
126.73 + * <pre>
126.74 + * myString = DateFormat.getDateInstance().format(myDate);
126.75 + * </pre>
126.76 + * <p>If you are formatting multiple dates, it is
126.77 + * more efficient to get the format and use it multiple times so that
126.78 + * the system doesn't have to fetch the information about the local
126.79 + * language and country conventions multiple times.
126.80 + * <pre>
126.81 + * DateFormat df = DateFormat.getDateInstance();
126.82 + * for (int i = 0; i < myDate.length; ++i) {
126.83 + * output.println(df.format(myDate[i]) + "; ");
126.84 + * }
126.85 + * </pre>
126.86 + * <p>To format a date for a different Locale, specify it in the
126.87 + * call to {@link #getDateInstance(int, Locale) getDateInstance()}.
126.88 + * <pre>
126.89 + * DateFormat df = DateFormat.getDateInstance(DateFormat.LONG, Locale.FRANCE);
126.90 + * </pre>
126.91 + * <p>You can use a DateFormat to parse also.
126.92 + * <pre>
126.93 + * myDate = df.parse(myString);
126.94 + * </pre>
126.95 + * <p>Use {@code getDateInstance} to get the normal date format for that country.
126.96 + * There are other static factory methods available.
126.97 + * Use {@code getTimeInstance} to get the time format for that country.
126.98 + * Use {@code getDateTimeInstance} to get a date and time format. You can pass in
126.99 + * different options to these factory methods to control the length of the
126.100 + * result; from {@link #SHORT} to {@link #MEDIUM} to {@link #LONG} to {@link #FULL}. The exact result depends
126.101 + * on the locale, but generally:
126.102 + * <ul><li>{@link #SHORT} is completely numeric, such as {@code 12.13.52} or {@code 3:30pm}
126.103 + * <li>{@link #MEDIUM} is longer, such as {@code Jan 12, 1952}
126.104 + * <li>{@link #LONG} is longer, such as {@code January 12, 1952} or {@code 3:30:32pm}
126.105 + * <li>{@link #FULL} is pretty completely specified, such as
126.106 + * {@code Tuesday, April 12, 1952 AD or 3:30:42pm PST}.
126.107 + * </ul>
126.108 + *
126.109 + * <p>You can also set the time zone on the format if you wish.
126.110 + * If you want even more control over the format or parsing,
126.111 + * (or want to give your users more control),
126.112 + * you can try casting the {@code DateFormat} you get from the factory methods
126.113 + * to a {@link SimpleDateFormat}. This will work for the majority
126.114 + * of countries; just remember to put it in a {@code try} block in case you
126.115 + * encounter an unusual one.
126.116 + *
126.117 + * <p>You can also use forms of the parse and format methods with
126.118 + * {@link ParsePosition} and {@link FieldPosition} to
126.119 + * allow you to
126.120 + * <ul><li>progressively parse through pieces of a string.
126.121 + * <li>align any particular field, or find out where it is for selection
126.122 + * on the screen.
126.123 + * </ul>

126.126 + *
126.127 + * <p>
126.128 + * Date formats are not synchronized.

127.54 +/**
127.55 + * <code>DateFormatSymbols</code> is a public class for encapsulating
127.56 + * localizable date-time formatting data, such as the names of the
127.57 + * months, the names of the days of the week, and the time zone data.
127.58 + * <code>DateFormat</code> and <code>SimpleDateFormat</code> both use
127.59 + * <code>DateFormatSymbols</code> to encapsulate this information.
127.60 + *
127.61 + * <p>
127.62 + * Typically you shouldn't use <code>DateFormatSymbols</code> directly.
127.63 + * Rather, you are encouraged to create a date-time formatter with the
127.64 + * <code>DateFormat</code> class's factory methods: <code>getTimeInstance</code>,
127.65 + * <code>getDateInstance</code>, or <code>getDateTimeInstance</code>.
127.66 + * These methods automatically create a <code>DateFormatSymbols</code> for
127.67 + * the formatter so that you don't have to. After the
127.68 + * formatter is created, you may modify its format pattern using the
127.69 + * <code>setPattern</code> method. For more information about
127.70 + * creating formatters using <code>DateFormat</code>'s factory methods,
127.71 + * see {@link DateFormat}.
127.72 + *
127.73 + * <p>
127.74 + * If you decide to create a date-time formatter with a specific
127.75 + * format pattern for a specific locale, you can do so with:
127.76 + * <blockquote>
127.77 + * <pre>
127.78 + * new SimpleDateFormat(aPattern, DateFormatSymbols.getInstance(aLocale)).
127.79 + * </pre>
127.80 + * </blockquote>
127.81 + *
127.82 + * <p>
127.83 + * <code>DateFormatSymbols</code> objects are cloneable. When you obtain
127.84 + * a <code>DateFormatSymbols</code> object, feel free to modify the
127.85 + * date-time formatting data. For instance, you can replace the localized
127.86 + * date-time format pattern characters with the ones that you feel easy
127.87 + * to remember. Or you can change the representative cities
127.88 + * to your favorite ones.
127.89 + *
127.90 + * <p>
127.91 + * New <code>DateFormatSymbols</code> subclasses may be added to support
127.92 + * <code>SimpleDateFormat</code> for date-time formatting for additional locales.

128.67 + *
128.68 + * <p>To obtain a <code>NumberFormat</code> for a specific locale, including the
128.69 + * default locale, call one of <code>NumberFormat</code>'s factory methods, such
128.70 + * as <code>getInstance()</code>. In general, do not call the
128.71 + * <code>DecimalFormat</code> constructors directly, since the
128.72 + * <code>NumberFormat</code> factory methods may return subclasses other than
128.73 + * <code>DecimalFormat</code>. If you need to customize the format object, do
128.74 + * something like this:
128.75 + *
128.76 + * <blockquote><pre>
128.77 + * NumberFormat f = NumberFormat.getInstance(loc);
128.78 + * if (f instanceof DecimalFormat) {
128.79 + * ((DecimalFormat) f).setDecimalSeparatorAlwaysShown(true);
128.80 + * }
128.81 + * </pre></blockquote>
128.82 + *
128.83 + * <p>A <code>DecimalFormat</code> comprises a <em>pattern</em> and a set of
128.84 + * <em>symbols</em>. The pattern may be set directly using
128.85 + * <code>applyPattern()</code>, or indirectly using the API methods. The
128.86 + * symbols are stored in a <code>DecimalFormatSymbols</code> object. When using
128.87 + * the <code>NumberFormat</code> factory methods, the pattern and symbols are
128.88 + * read from localized <code>ResourceBundle</code>s.
128.89 + *
128.90 + * <h4>Patterns</h4>
128.91 + *
128.92 + * <code>DecimalFormat</code> patterns have the following syntax:
128.93 + * <blockquote><pre>

128.125 + * <i>MinimumExponent:</i>
128.126 + * 0 <i>MinimumExponent<sub>opt</sub></i>
128.127 + * </pre></blockquote>
128.128 + *
128.129 + * <p>A <code>DecimalFormat</code> pattern contains a positive and negative
128.130 + * subpattern, for example, <code>"#,##0.00;(#,##0.00)"</code>. Each
128.131 + * subpattern has a prefix, numeric part, and suffix. The negative subpattern
128.132 + * is optional; if absent, then the positive subpattern prefixed with the
128.133 + * localized minus sign (<code>'-'</code> in most locales) is used as the
128.134 + * negative subpattern. That is, <code>"0.00"</code> alone is equivalent to
128.135 + * <code>"0.00;-0.00"</code>. If there is an explicit negative subpattern, it
128.136 + * serves only to specify the negative prefix and suffix; the number of digits,
128.137 + * minimal digits, and other characteristics are all the same as the positive
128.138 + * pattern. That means that <code>"#,##0.0#;(#)"</code> produces precisely
128.139 + * the same behavior as <code>"#,##0.0#;(#,##0.0#)"</code>.
128.140 + *
128.141 + * <p>The prefixes, suffixes, and various symbols used for infinity, digits,
128.142 + * thousands separators, decimal separators, etc. may be set to arbitrary
128.143 + * values, and they will appear properly during formatting. However, care must
128.144 + * be taken that the symbols and strings do not conflict, or parsing will be
128.145 + * unreliable. For example, either the positive and negative prefixes or the
128.146 + * suffixes must be distinct for <code>DecimalFormat.parse()</code> to be able
128.147 + * to distinguish positive from negative values. (If they are identical, then
128.148 + * <code>DecimalFormat</code> will behave as if no negative subpattern was
128.149 + * specified.) Another example is that the decimal separator and thousands
128.150 + * separator should be distinct characters, or parsing will be impossible.
128.151 + *
128.152 + * <p>The grouping separator is commonly used for thousands, but in some
128.153 + * countries it separates ten-thousands. The grouping size is a constant number
128.154 + * of digits between the grouping characters, such as 3 for 100,000,000 or 4 for
128.155 + * 1,0000,0000. If you supply a pattern with multiple grouping characters, the
128.156 + * interval between the last one and the end of the integer is the one that is
128.157 + * used. So <code>"#,##,###,####"</code> == <code>"######,####"</code> ==
128.158 + * <code>"##,####,####"</code>.
128.159 + *
128.160 + * <h4>Special Pattern Characters</h4>
128.161 + *
128.162 + * <p>Many characters in a pattern are taken literally; they are matched during
128.163 + * parsing and output unchanged during formatting. Special characters, on the
128.164 + * other hand, stand for other characters, strings, or classes of characters.
128.165 + * They must be quoted, unless noted otherwise, if they are to appear in the
128.166 + * prefix or suffix as literals.
128.167 + *
128.168 + * <p>The characters listed here are used in non-localized patterns. Localized
128.169 + * patterns use the corresponding characters taken from this formatter's
128.170 + * <code>DecimalFormatSymbols</code> object instead, and these characters lose
128.171 + * their special status. Two exceptions are the currency sign and quote, which
128.172 + * are not localized.

128.246 + *
128.247 + * <h4>Scientific Notation</h4>
128.248 + *
128.249 + * <p>Numbers in scientific notation are expressed as the product of a mantissa
128.250 + * and a power of ten, for example, 1234 can be expressed as 1.234 x 10^3. The
128.251 + * mantissa is often in the range 1.0 <= x < 10.0, but it need not be.
128.252 + * <code>DecimalFormat</code> can be instructed to format and parse scientific
128.253 + * notation <em>only via a pattern</em>; there is currently no factory method
128.254 + * that creates a scientific notation format. In a pattern, the exponent
128.255 + * character immediately followed by one or more digit characters indicates
128.256 + * scientific notation. Example: <code>"0.###E0"</code> formats the number
128.257 + * 1234 as <code>"1.234E3"</code>.
128.258 + *
128.259 + * <ul>
128.260 + * <li>The number of digit characters after the exponent character gives the
128.261 + * minimum exponent digit count. There is no maximum. Negative exponents are
128.262 + * formatted using the localized minus sign, <em>not</em> the prefix and suffix
128.263 + * from the pattern. This allows patterns such as <code>"0.###E0 m/s"</code>.
128.264 + *
128.265 + * <li>The minimum and maximum number of integer digits are interpreted
128.266 + * together:
128.267 + *
128.268 + * <ul>
128.269 + * <li>If the maximum number of integer digits is greater than their minimum number
128.270 + * and greater than 1, it forces the exponent to be a multiple of the maximum
128.271 + * number of integer digits, and the minimum number of integer digits to be
128.272 + * interpreted as 1. The most common use of this is to generate
128.273 + * <em>engineering notation</em>, in which the exponent is a multiple of three,
128.274 + * e.g., <code>"##0.#####E0"</code>. Using this pattern, the number 12345
128.275 + * formats to <code>"12.345E3"</code>, and 123456 formats to
128.276 + * <code>"123.456E3"</code>.
128.277 + *
128.278 + * <li>Otherwise, the minimum number of integer digits is achieved by adjusting the
128.279 + * exponent. Example: 0.00123 formatted with <code>"00.###E0"</code> yields
128.280 + * <code>"12.3E-4"</code>.
128.281 + * </ul>
128.282 + *
128.283 + * <li>The number of significant digits in the mantissa is the sum of the
128.284 + * <em>minimum integer</em> and <em>maximum fraction</em> digits, and is
128.285 + * unaffected by the maximum integer digits. For example, 12345 formatted with
128.286 + * <code>"##0.##E0"</code> is <code>"12.3E3"</code>. To show all digits, set
128.287 + * the significant digits count to zero. The number of significant digits
128.288 + * does not affect parsing.
128.289 + *
128.290 + * <li>Exponential patterns may not contain grouping separators.
128.291 + * </ul>
128.292 + *
128.293 + * <h4>Rounding</h4>
128.294 + *
128.295 + * <code>DecimalFormat</code> provides rounding modes defined in
128.296 + * {@link java.math.RoundingMode} for formatting. By default, it uses
128.297 + * {@link java.math.RoundingMode#HALF_EVEN RoundingMode.HALF_EVEN}.
128.298 + *
128.299 + * <h4>Digits</h4>
128.300 + *
128.301 + * For formatting, <code>DecimalFormat</code> uses the ten consecutive
128.302 + * characters starting with the localized zero digit defined in the
128.303 + * <code>DecimalFormatSymbols</code> object as digits. For parsing, these
128.304 + * digits as well as all Unicode decimal digits, as defined by
128.305 + * {@link Character#digit Character.digit}, are recognized.
128.306 + *
128.307 + * <h4>Special Values</h4>
128.308 + *
128.309 + * <p><code>NaN</code> is formatted as a string, which typically has a single character
128.310 + * <code>\uFFFD</code>. This string is determined by the
128.311 + * <code>DecimalFormatSymbols</code> object. This is the only value for which
128.312 + * the prefixes and suffixes are not used.
128.313 + *
128.314 + * <p>Infinity is formatted as a string, which typically has a single character
128.315 + * <code>\u221E</code>, with the positive or negative prefixes and suffixes
128.316 + * applied. The infinity string is determined by the
128.317 + * <code>DecimalFormatSymbols</code> object.
128.318 + *
128.319 + * <p>Negative zero (<code>"-0"</code>) parses to
128.320 + * <ul>
128.321 + * <li><code>BigDecimal(0)</code> if <code>isParseBigDecimal()</code> is
128.322 + * true,
128.323 + * <li><code>Long(0)</code> if <code>isParseBigDecimal()</code> is false
128.324 + * and <code>isParseIntegerOnly()</code> is true,
128.325 + * <li><code>Double(-0.0)</code> if both <code>isParseBigDecimal()</code>
128.326 + * and <code>isParseIntegerOnly()</code> are false.
128.327 + * </ul>
128.328 + *
128.329 + * <h4><a name="synchronization">Synchronization</a></h4>
128.330 + *
128.331 + * <p>
128.332 + * Decimal formats are generally not synchronized.
128.333 + * It is recommended to create separate format instances for each thread.
128.334 + * If multiple threads access a format concurrently, it must be synchronized
128.335 + * externally.
128.336 + *
128.337 + * <h4>Example</h4>
128.338 + *
128.339 + * <blockquote><pre>
128.340 + * <strong>// Print out a number using the localized number, integer, currency,
128.341 + * // and percent format for each locale</strong>

132.45 + * <code>FieldPosition</code> is a simple class used by <code>Format</code>
132.46 + * and its subclasses to identify fields in formatted output. Fields can
132.47 + * be identified in two ways:
132.48 + * <ul>
132.49 + * <li>By an integer constant, whose names typically end with
132.50 + * <code>_FIELD</code>. The constants are defined in the various
132.51 + * subclasses of <code>Format</code>.
132.52 + * <li>By a <code>Format.Field</code> constant, see <code>ERA_FIELD</code>
132.53 + * and its friends in <code>DateFormat</code> for an example.
132.54 + * </ul>
132.55 + * <p>
132.56 + * <code>FieldPosition</code> keeps track of the position of the
132.57 + * field within the formatted output with two indices: the index
132.58 + * of the first character of the field and the index of the last
132.59 + * character of the field.

132.63 + * <code>Format</code> classes requires a <code>FieldPosition</code>
132.64 + * object as an argument. You use this <code>format</code> method
132.65 + * to perform partial formatting or to get information about the
132.66 + * formatted output (such as the position of a field).
132.67 + *

133.46 +/**
133.47 + * <code>Format</code> is an abstract base class for formatting locale-sensitive
133.48 + * information such as dates, messages, and numbers.
133.49 + *
133.50 + * <p>
133.51 + * <code>Format</code> defines the programming interface for formatting
133.52 + * locale-sensitive objects into <code>String</code>s (the
133.53 + * <code>format</code> method) and for parsing <code>String</code>s back
133.54 + * into objects (the <code>parseObject</code> method).
133.55 + *
133.56 + * <p>
133.57 + * Generally, a format's <code>parseObject</code> method must be able to parse
133.58 + * any string formatted by its <code>format</code> method. However, there may
133.59 + * be exceptional cases where this is not possible. For example, a
133.60 + * <code>format</code> method might create two adjacent integer numbers with
133.61 + * no separator in between, and in this case the <code>parseObject</code> could
133.62 + * not tell which digits belong to which number.
133.63 + *
133.64 + * <h4>Subclassing</h4>
133.65 + *
133.66 + * <p>
133.67 + * The Java Platform provides three specialized subclasses of <code>Format</code>--
133.68 + * <code>DateFormat</code>, <code>MessageFormat</code>, and
133.69 + * <code>NumberFormat</code>--for formatting dates, messages, and numbers,
133.70 + * respectively.
133.71 + * <p>
133.72 + * Concrete subclasses must implement three methods:
133.73 + * <ol>
133.74 + * <li> <code>format(Object obj, StringBuffer toAppendTo, FieldPosition pos)</code>
133.75 + * <li> <code>formatToCharacterIterator(Object obj)</code>
133.76 + * <li> <code>parseObject(String source, ParsePosition pos)</code>
133.77 + * </ol>
133.78 + * These general methods allow polymorphic parsing and formatting of objects
133.79 + * and are used, for example, by <code>MessageFormat</code>.
133.80 + * Subclasses often also provide additional <code>format</code> methods for
133.81 + * specific input types as well as <code>parse</code> methods for specific
133.82 + * result types. Any <code>parse</code> method that does not take a
133.83 + * <code>ParsePosition</code> argument should throw <code>ParseException</code>
133.84 + * when no text in the required format is at the beginning of the input text.
133.85 + *
133.86 + * <p>
133.87 + * Most subclasses will also implement the following factory methods:
133.88 + * <ol>
133.89 + * <li>
133.90 + * <code>getInstance</code> for getting a useful format object appropriate
133.91 + * for the current locale
133.92 + * <li>
133.93 + * <code>getInstance(Locale)</code> for getting a useful format
133.94 + * object appropriate for the specified locale
133.95 + * </ol>
133.96 + * In addition, some subclasses may also implement other
133.97 + * <code>getXxxxInstance</code> methods for more specialized control. For
133.98 + * example, the <code>NumberFormat</code> class provides
133.99 + * <code>getPercentInstance</code> and <code>getCurrencyInstance</code>
133.100 + * methods for getting specialized number formatters.
133.101 + *
133.102 + * <p>
133.103 + * Subclasses of <code>Format</code> that allow programmers to create objects
133.104 + * for locales (with <code>getInstance(Locale)</code> for example)
133.105 + * must also implement the following class method:
133.106 + * <blockquote>
133.107 + * <pre>
133.108 + * public static Locale[] getAvailableLocales()
133.109 + * </pre>
133.110 + * </blockquote>
133.111 + *
133.112 + * <p>
133.113 + * And finally subclasses may define a set of constants to identify the various
133.114 + * fields in the formatted output. These constants are used to create a FieldPosition
133.115 + * object which identifies what information is contained in the field and its
133.116 + * position in the formatted result. These constants should be named
133.117 + * <code><em>item</em>_FIELD</code> where <code><em>item</em></code> identifies
133.118 + * the field. For examples of these constants, see <code>ERA_FIELD</code> and its
133.119 + * friends in {@link DateFormat}.
133.120 + *
133.121 + * <h4><a name="synchronization">Synchronization</a></h4>
133.122 + *
133.123 + * <p>
133.124 + * Formats are generally not synchronized.
133.125 + * It is recommended to create separate format instances for each thread.
133.126 + * If multiple threads access a format concurrently, it must be synchronized
133.127 + * externally.

134.55 +/**
134.56 + * <code>MessageFormat</code> provides a means to produce concatenated
134.57 + * messages in a language-neutral way. Use this to construct messages
134.58 + * displayed for end users.
134.59 + *
134.60 + * <p>
134.61 + * <code>MessageFormat</code> takes a set of objects, formats them, then
134.62 + * inserts the formatted strings into the pattern at the appropriate places.
134.63 + *
134.64 + * <p>
134.65 + * <strong>Note:</strong>
134.66 + * <code>MessageFormat</code> differs from the other <code>Format</code>
134.67 + * classes in that you create a <code>MessageFormat</code> object with one
134.68 + * of its constructors (not with a <code>getInstance</code> style factory
134.69 + * method). The factory methods aren't necessary because <code>MessageFormat</code>
134.70 + * itself doesn't implement locale specific behavior. Any locale specific
134.71 + * behavior is defined by the pattern that you provide as well as the
134.72 + * subformats used for inserted arguments.
134.73 + *
134.74 + * <h4><a name="patterns">Patterns and Their Interpretation</a></h4>
134.75 + *
134.76 + * <code>MessageFormat</code> uses patterns of the following form:
134.77 + * <blockquote><pre>
134.78 + * <i>MessageFormatPattern:</i>
134.79 + * <i>String</i>
134.80 + * <i>MessageFormatPattern</i> <i>FormatElement</i> <i>String</i>
134.81 + *
134.82 + * <i>FormatElement:</i>
134.83 + * { <i>ArgumentIndex</i> }
134.84 + * { <i>ArgumentIndex</i> , <i>FormatType</i> }
134.85 + * { <i>ArgumentIndex</i> , <i>FormatType</i> , <i>FormatStyle</i> }
134.86 + *
134.87 + * <i>FormatType: one of </i>
134.88 + * number date time choice
134.89 + *
134.90 + * <i>FormatStyle:</i>
134.91 + * short
134.92 + * medium
134.93 + * long
134.94 + * full
134.95 + * integer
134.96 + * currency
134.97 + * percent
134.98 + * <i>SubformatPattern</i>
134.99 + * </pre></blockquote>
134.100 + *
134.101 + * <p>Within a <i>String</i>, a pair of single quotes can be used to
134.102 + * quote any arbitrary characters except single quotes. For example,
134.103 + * pattern string <code>"'{0}'"</code> represents string
134.104 + * <code>"{0}"</code>, not a <i>FormatElement</i>. A single quote itself
134.105 + * must be represented by doubled single quotes {@code ''} throughout a
134.106 + * <i>String</i>. For example, pattern string <code>"'{''}'"</code> is
134.107 + * interpreted as a sequence of <code>'{</code> (start of quoting and a
134.108 + * left curly brace), <code>''</code> (a single quote), and
134.109 + * <code>}'</code> (a right curly brace and end of quoting),
134.110 + * <em>not</em> <code>'{'</code> and <code>'}'</code> (quoted left and
134.111 + * right curly braces): representing string <code>"{'}"</code>,
134.112 + * <em>not</em> <code>"{}"</code>.
134.113 + *
134.114 + * <p>A <i>SubformatPattern</i> is interpreted by its corresponding
134.115 + * subformat, and subformat-dependent pattern rules apply. For example,
134.116 + * pattern string <code>"{1,number,<u>$'#',##</u>}"</code>
134.117 + * (<i>SubformatPattern</i> with underline) will produce a number format
134.118 + * with the pound-sign quoted, with a result such as: {@code
134.119 + * "$#31,45"}. Refer to each {@code Format} subclass documentation for
134.120 + * details.
134.121 + *
134.122 + * <p>Any unmatched quote is treated as closed at the end of the given
134.123 + * pattern. For example, pattern string {@code "'{0}"} is treated as
134.124 + * pattern {@code "'{0}'"}.
134.125 + *
134.126 + * <p>Any curly braces within an unquoted pattern must be balanced. For
134.127 + * example, <code>"ab {0} de"</code> and <code>"ab '}' de"</code> are
134.128 + * valid patterns, but <code>"ab {0'}' de"</code>, <code>"ab } de"</code>
134.129 + * and <code>"''{''"</code> are not.
134.130 + *
134.131 + * <p>
134.132 + * <dl><dt><b>Warning:</b><dd>The rules for using quotes within message
134.133 + * format patterns unfortunately have shown to be somewhat confusing.
134.134 + * In particular, it isn't always obvious to localizers whether single
134.135 + * quotes need to be doubled or not. Make sure to inform localizers about
134.136 + * the rules, and tell them (for example, by using comments in resource
134.137 + * bundle source files) which strings will be processed by {@code MessageFormat}.
134.138 + * Note that localizers may need to use single quotes in translated
134.139 + * strings where the original version doesn't have them.
134.140 + * </dl>
134.141 + * <p>
134.142 + * The <i>ArgumentIndex</i> value is a non-negative integer written
134.143 + * using the digits {@code '0'} through {@code '9'}, and represents an index into the
134.144 + * {@code arguments} array passed to the {@code format} methods
134.145 + * or the result array returned by the {@code parse} methods.
134.146 + * <p>
134.147 + * The <i>FormatType</i> and <i>FormatStyle</i> values are used to create
134.148 + * a {@code Format} instance for the format element. The following
134.149 + * table shows how the values map to {@code Format} instances. Combinations not
134.150 + * shown in the table are illegal. A <i>SubformatPattern</i> must
134.151 + * be a valid pattern string for the {@code Format} subclass used.

134.223 + * <h4>Usage Information</h4>
134.224 + *
134.225 + * <p>
134.226 + * Here are some examples of usage.
134.227 + * In real internationalized programs, the message format pattern and other
134.228 + * static strings will, of course, be obtained from resource bundles.
134.229 + * Other parameters will be dynamically determined at runtime.
134.230 + * <p>
134.231 + * The first example uses the static method <code>MessageFormat.format</code>,
134.232 + * which internally creates a <code>MessageFormat</code> for one-time use:
134.233 + * <blockquote><pre>
134.234 + * int planet = 7;
134.235 + * String event = "a disturbance in the Force";
134.236 + *
134.237 + * String result = MessageFormat.format(
134.238 + * "At {1,time} on {1,date}, there was {2} on planet {0,number,integer}.",
134.239 + * planet, new Date(), event);
134.240 + * </pre></blockquote>
134.241 + * The output is:
134.242 + * <blockquote><pre>
134.243 + * At 12:30 PM on Jul 3, 2053, there was a disturbance in the Force on planet 7.
134.244 + * </pre></blockquote>
134.245 + *
134.246 + * <p>
134.247 + * The following example creates a <code>MessageFormat</code> instance that
134.248 + * can be used repeatedly:
134.249 + * <blockquote><pre>
134.250 + * int fileCount = 1273;
134.251 + * String diskName = "MyDisk";
134.252 + * Object[] testArgs = {new Long(fileCount), diskName};
134.253 + *
134.254 + * MessageFormat form = new MessageFormat(
134.255 + * "The disk \"{1}\" contains {0} file(s).");
134.256 + *
134.257 + * System.out.println(form.format(testArgs));
134.258 + * </pre></blockquote>
134.259 + * The output with different values for <code>fileCount</code>:
134.260 + * <blockquote><pre>
134.261 + * The disk "MyDisk" contains 0 file(s).
134.262 + * The disk "MyDisk" contains 1 file(s).
134.263 + * The disk "MyDisk" contains 1,273 file(s).
134.264 + * </pre></blockquote>
134.265 + *
134.266 + * <p>
134.267 + * For more sophisticated patterns, you can use a <code>ChoiceFormat</code>
134.268 + * to produce correct forms for singular and plural:
134.269 + * <blockquote><pre>
134.270 + * MessageFormat form = new MessageFormat("The disk \"{1}\" contains {0}.");
134.271 + * double[] filelimits = {0,1,2};
134.272 + * String[] filepart = {"no files","one file","{0,number} files"};
134.273 + * ChoiceFormat fileform = new ChoiceFormat(filelimits, filepart);
134.274 + * form.setFormatByArgumentIndex(0, fileform);
134.275 + *
134.276 + * int fileCount = 1273;
134.277 + * String diskName = "MyDisk";
134.278 + * Object[] testArgs = {new Long(fileCount), diskName};
134.279 + *
134.280 + * System.out.println(form.format(testArgs));
134.281 + * </pre></blockquote>
134.282 + * The output with different values for <code>fileCount</code>:
134.283 + * <blockquote><pre>
134.284 + * The disk "MyDisk" contains no files.
134.285 + * The disk "MyDisk" contains one file.
134.286 + * The disk "MyDisk" contains 1,273 files.
134.287 + * </pre></blockquote>
134.288 + *
134.289 + * <p>
134.290 + * You can create the <code>ChoiceFormat</code> programmatically, as in the
134.291 + * above example, or by using a pattern. See {@link ChoiceFormat}
134.292 + * for more information.
134.293 + * <blockquote><pre>
134.294 + * form.applyPattern(
134.295 + * "There {0,choice,0#are no files|1#is one file|1<are {0,number,integer} files}.");
134.296 + * </pre></blockquote>
134.297 + *
134.298 + * <p>
134.299 + * <strong>Note:</strong> As we see above, the string produced
134.300 + * by a <code>ChoiceFormat</code> in <code>MessageFormat</code> is treated as special;
134.301 + * occurrences of '{' are used to indicate subformats, and cause recursion.
134.302 + * If you create both a <code>MessageFormat</code> and <code>ChoiceFormat</code>
134.303 + * programmatically (instead of using the string patterns), then be careful not to
134.304 + * produce a format that recurses on itself, which will cause an infinite loop.
134.305 + * <p>
134.306 + * When a single argument is parsed more than once in the string, the last match
134.307 + * will be the final result of the parsing. For example,
134.308 + * <blockquote><pre>
134.309 + * MessageFormat mf = new MessageFormat("{0,number,#.##}, {0,number,#.#}");
134.310 + * Object[] objs = {new Double(3.1415)};
134.311 + * String result = mf.format( objs );
134.312 + * // result now equals "3.14, 3.1"
134.313 + * objs = null;
134.314 + * objs = mf.parse(result, new ParsePosition(0));
134.315 + * // objs now equals {new Double(3.1)}
134.316 + * </pre></blockquote>
134.317 + *
134.318 + * <p>
134.319 + * Likewise, parsing with a {@code MessageFormat} object using patterns containing
134.320 + * multiple occurrences of the same argument would return the last match. For
134.321 + * example,
134.322 + * <blockquote><pre>
134.323 + * MessageFormat mf = new MessageFormat("{0}, {0}, {0}");
134.324 + * String forParsing = "x, y, z";
134.325 + * Object[] objs = mf.parse(forParsing, new ParsePosition(0));
134.326 + * // result now equals {new String("z")}
134.327 + * </pre></blockquote>
134.328 + *
134.329 + * <h4><a name="synchronization">Synchronization</a></h4>
134.330 + *
134.331 + * <p>
134.332 + * Message formats are not synchronized.
134.333 + * It is recommended to create separate format instances for each thread.
134.334 + * If multiple threads access a format concurrently, it must be synchronized
134.335 + * externally.

134.925 + * <li>If the format of an argument loses information, such as

134.929 + * <li>Will not always find a match (or the correct match)
134.930 + * if some part of the parse is ambiguous.
134.931 + * For example, if the pattern "{1},{2}" is used with the
134.932 + * string arguments {"a,b", "c"}, it will format as "a,b,c".
134.933 + * When the result is parsed, it will return {"a", "b,c"}.
134.934 + * <li>If a single argument is parsed more than once in the string,

134.937 + * When the parse fails, use ParsePosition.getErrorIndex() to find out

135.59 +/**
135.60 + * <code>NumberFormat</code> is the abstract base class for all number
135.61 + * formats. This class provides the interface for formatting and parsing
135.62 + * numbers. <code>NumberFormat</code> also provides methods for determining
135.63 + * which locales have number formats, and what their names are.
135.64 + *
135.65 + * <p>
135.66 + * <code>NumberFormat</code> helps you to format and parse numbers for any locale.
135.67 + * Your code can be completely independent of the locale conventions for
135.68 + * decimal points, thousands-separators, or even the particular decimal
135.69 + * digits used, or whether the number format is even decimal.
135.70 + *
135.71 + * <p>
135.72 + * To format a number for the current Locale, use one of the factory
135.73 + * class methods:
135.74 + * <blockquote>
135.75 + * <pre>
135.76 + * myString = NumberFormat.getInstance().format(myNumber);
135.77 + * </pre>
135.78 + * </blockquote>
135.79 + * If you are formatting multiple numbers, it is
135.80 + * more efficient to get the format and use it multiple times so that
135.81 + * the system doesn't have to fetch the information about the local
135.82 + * language and country conventions multiple times.
135.83 + * <blockquote>
135.84 + * <pre>
135.85 + * NumberFormat nf = NumberFormat.getInstance();
135.86 + * for (int i = 0; i < myNumber.length; ++i) {
135.87 + * output.println(nf.format(myNumber[i]) + "; ");
135.88 + * }
135.89 + * </pre>
135.90 + * </blockquote>
135.91 + * To format a number for a different Locale, specify it in the
135.92 + * call to <code>getInstance</code>.
135.93 + * <blockquote>
135.94 + * <pre>
135.95 + * NumberFormat nf = NumberFormat.getInstance(Locale.FRENCH);
135.96 + * </pre>
135.97 + * </blockquote>
135.98 + * You can also use a <code>NumberFormat</code> to parse numbers:
135.99 + * <blockquote>
135.100 + * <pre>
135.101 + * myNumber = nf.parse(myString);
135.102 + * </pre>
135.103 + * </blockquote>
135.104 + * Use <code>getInstance</code> or <code>getNumberInstance</code> to get the
135.105 + * normal number format. Use <code>getIntegerInstance</code> to get an
135.106 + * integer number format. Use <code>getCurrencyInstance</code> to get the
135.107 + * currency number format. And use <code>getPercentInstance</code> to get a
135.108 + * format for displaying percentages. With this format, a fraction like
135.109 + * 0.53 is displayed as 53%.
135.110 + *
135.111 + * <p>
135.112 + * You can also control the display of numbers with such methods as
135.113 + * <code>setMinimumFractionDigits</code>.
135.114 + * If you want even more control over the format or parsing,
135.115 + * or want to give your users more control,
135.116 + * you can try casting the <code>NumberFormat</code> you get from the factory methods
135.117 + * to a <code>DecimalFormat</code>. This will work for the vast majority
135.118 + * of locales; just remember to put it in a <code>try</code> block in case you
135.119 + * encounter an unusual one.
135.120 + *
135.121 + * <p>
135.122 + * NumberFormat and DecimalFormat are designed such that some controls
135.123 + * work for formatting and others work for parsing. The following is
135.124 + * the detailed description for each these control methods,
135.125 + * <p>
135.126 + * setParseIntegerOnly : only affects parsing, e.g.
135.127 + * if true, "3456.78" -> 3456 (and leaves the parse position just after index 6)
135.128 + * if false, "3456.78" -> 3456.78 (and leaves the parse position just after index 8)
135.129 + * This is independent of formatting. If you want to not show a decimal point
135.130 + * where there might be no digits after the decimal point, use
135.131 + * setDecimalSeparatorAlwaysShown.
135.132 + * <p>
135.133 + * setDecimalSeparatorAlwaysShown : only affects formatting, and only where
135.134 + * there might be no digits after the decimal point, such as with a pattern
135.135 + * like "#,##0.##", e.g.,
135.136 + * if true, 3456.00 -> "3,456."
135.137 + * if false, 3456.00 -> "3456"
135.138 + * This is independent of parsing. If you want parsing to stop at the decimal
135.139 + * point, use setParseIntegerOnly.
135.140 + *
135.141 + * <p>
135.142 + * You can also use forms of the <code>parse</code> and <code>format</code>
135.143 + * methods with <code>ParsePosition</code> and <code>FieldPosition</code> to
135.144 + * allow you to:
135.145 + * <ul>
135.146 + * <li> progressively parse through pieces of a string
135.147 + * <li> align the decimal point and other areas
135.148 + * </ul>
135.149 + * For example, you can align numbers in two ways:
135.150 + * <ol>
135.151 + * <li> If you are using a monospaced font with spacing for alignment,
135.152 + * you can pass the <code>FieldPosition</code> in your format call, with
135.153 + * <code>field</code> = <code>INTEGER_FIELD</code>. On output,
135.154 + * <code>getEndIndex</code> will be set to the offset between the
135.155 + * last character of the integer and the decimal. Add
135.156 + * (desiredSpaceCount - getEndIndex) spaces at the front of the string.
135.157 + *
135.158 + * <li> If you are using proportional fonts,
135.159 + * instead of padding with spaces, measure the width
135.160 + * of the string in pixels from the start to <code>getEndIndex</code>.
135.161 + * Then move the pen by
135.162 + * (desiredPixelWidth - widthToAlignmentPoint) before drawing the text.
135.163 + * It also works where there is no decimal, but possibly additional
135.164 + * characters at the end, e.g., with parentheses in negative
135.165 + * numbers: "(12)" for -12.
135.166 + * </ol>

138.60 +/**
138.61 + * <code>SimpleDateFormat</code> is a concrete class for formatting and
138.62 + * parsing dates in a locale-sensitive manner. It allows for formatting
138.63 + * (date -> text), parsing (text -> date), and normalization.
138.64 + *
138.65 + * <p>
138.66 + * <code>SimpleDateFormat</code> allows you to start by choosing
138.67 + * any user-defined patterns for date-time formatting. However, you
138.68 + * are encouraged to create a date-time formatter with either
138.69 + * <code>getTimeInstance</code>, <code>getDateInstance</code>, or
138.70 + * <code>getDateTimeInstance</code> in <code>DateFormat</code>. Each
138.71 + * of these class methods can return a date/time formatter initialized
138.72 + * with a default format pattern. You may modify the format pattern
138.73 + * using the <code>applyPattern</code> methods as desired.
138.74 + * For more information on using these methods, see
138.75 + * {@link DateFormat}.
138.76 + *
138.77 + * <h4>Date and Time Patterns</h4>
138.78 + * <p>
138.79 + * Date and time formats are specified by <em>date and time pattern</em>
138.80 + * strings.
138.81 + * Within date and time pattern strings, unquoted letters from
138.82 + * <code>'A'</code> to <code>'Z'</code> and from <code>'a'</code> to
138.83 + * <code>'z'</code> are interpreted as pattern letters representing the
138.84 + * components of a date or time string.
138.85 + * Text can be quoted using single quotes (<code>'</code>) to avoid
138.86 + * interpretation.
138.87 + * <code>"''"</code> represents a single quote.
138.88 + * All other characters are not interpreted; they're simply copied into the
138.89 + * output string during formatting or matched against the input string
138.90 + * during parsing.
138.91 + * <p>
138.92 + * The following pattern letters are defined (all other characters from
138.93 + * <code>'A'</code> to <code>'Z'</code> and from <code>'a'</code> to
138.94 + * <code>'z'</code> are reserved):

138.214 + * Pattern letters are usually repeated, as their number determines the
138.215 + * exact presentation:
138.216 + * <ul>
138.217 + * <li><strong><a name="text">Text:</a></strong>
138.218 + * For formatting, if the number of pattern letters is 4 or more,
138.219 + * the full form is used; otherwise a short or abbreviated form
138.220 + * is used if available.
138.221 + * For parsing, both forms are accepted, independent of the number
138.222 + * of pattern letters.<br><br></li>
138.223 + * <li><strong><a name="number">Number:</a></strong>
138.224 + * For formatting, the number of pattern letters is the minimum
138.225 + * number of digits, and shorter numbers are zero-padded to this amount.
138.226 + * For parsing, the number of pattern letters is ignored unless
138.227 + * it's needed to separate two adjacent fields.<br><br></li>
138.228 + * <li><strong><a name="year">Year:</a></strong>
138.229 + * If the formatter's {@link #getCalendar() Calendar} is the Gregorian
138.230 + * calendar, the following rules are applied.<br>
138.231 + * <ul>
138.232 + * <li>For formatting, if the number of pattern letters is 2, the year
138.233 + * is truncated to 2 digits; otherwise it is interpreted as a
138.234 + * <a href="#number">number</a>.
138.235 + * <li>For parsing, if the number of pattern letters is more than 2,
138.236 + * the year is interpreted literally, regardless of the number of
138.237 + * digits. So using the pattern "MM/dd/yyyy", "01/11/12" parses to
138.238 + * Jan 11, 12 A.D.
138.239 + * <li>For parsing with the abbreviated year pattern ("y" or "yy"),
138.240 + * <code>SimpleDateFormat</code> must interpret the abbreviated year
138.241 + * relative to some century. It does this by adjusting dates to be
138.242 + * within 80 years before and 20 years after the time the <code>SimpleDateFormat</code>
138.243 + * instance is created. For example, using a pattern of "MM/dd/yy" and a
138.244 + * <code>SimpleDateFormat</code> instance created on Jan 1, 1997, the string
138.245 + * "01/11/12" would be interpreted as Jan 11, 2012 while the string "05/04/64"
138.246 + * would be interpreted as May 4, 1964.
138.247 + * During parsing, only strings consisting of exactly two digits, as defined by
138.248 + * {@link Character#isDigit(char)}, will be parsed into the default century.
138.249 + * Any other numeric string, such as a one digit string, a three or more digit
138.250 + * string, or a two digit string that isn't all digits (for example, "-1"), is
138.251 + * interpreted literally. So "01/02/3" or "01/02/003" are parsed, using the
138.252 + * same pattern, as Jan 2, 3 AD. Likewise, "01/02/-3" is parsed as Jan 2, 4 BC.
138.253 + * </ul>
138.254 + * Otherwise, calendar system specific forms are applied.
138.255 + * For both formatting and parsing, if the number of pattern
138.256 + * letters is 4 or more, a calendar specific {@linkplain
138.257 + * Calendar#LONG long form} is used. Otherwise, a calendar
138.258 + * specific {@linkplain Calendar#SHORT short or abbreviated form}
138.259 + * is used.<br>
138.260 + * <br>
138.261 + * If week year {@code 'Y'} is specified and the {@linkplain
138.262 + * #getCalendar() calendar} doesn't support any <a
138.263 + * href="../util/GregorianCalendar.html#week_year"> week
138.264 + * years</a>, the calendar year ({@code 'y'}) is used instead. The
138.265 + * support of week years can be tested with a call to {@link
138.266 + * DateFormat#getCalendar() getCalendar()}.{@link
138.267 + * java.util.Calendar#isWeekDateSupported()
138.268 + * isWeekDateSupported()}.<br><br></li>
138.269 + * <li><strong><a name="month">Month:</a></strong>
138.270 + * If the number of pattern letters is 3 or more, the month is
138.271 + * interpreted as <a href="#text">text</a>; otherwise,
138.272 + * it is interpreted as a <a href="#number">number</a>.<br><br></li>
138.273 + * <li><strong><a name="timezone">General time zone:</a></strong>
138.274 + * Time zones are interpreted as <a href="#text">text</a> if they have
138.275 + * names. For time zones representing a GMT offset value, the

138.329 + * is ignored. For example, if the pattern is {@code "X"} and the time zone is
138.330 + * {@code "GMT+05:30"}, {@code "+05"} is produced.
138.331 + *
138.332 + * <p>For parsing, {@code "Z"} is parsed as the UTC time zone designator.
138.333 + * <a href="#timezone">General time zones</a> are <em>not</em> accepted.
138.334 + *
138.335 + * <p>If the number of pattern letters is 4 or more, {@link

138.338 + * pattern}.
138.339 + * </ul>
138.340 + * <code>SimpleDateFormat</code> also supports <em>localized date and time
138.341 + * pattern</em> strings. In these strings, the pattern letters described above
138.342 + * may be replaced with other, locale dependent, pattern letters.
138.343 + * <code>SimpleDateFormat</code> does not deal with the localization of text
138.344 + * other than the pattern letters; that's up to the client of the class.

140.57 +/**
140.58 + * The <code>Calendar</code> class is an abstract class that provides methods
140.59 + * for converting between a specific instant in time and a set of {@link
140.60 + * #fields calendar fields} such as <code>YEAR</code>, <code>MONTH</code>,
140.61 + * <code>DAY_OF_MONTH</code>, <code>HOUR</code>, and so on, and for
140.62 + * manipulating the calendar fields, such as getting the date of the next
140.63 + * week. An instant in time can be represented by a millisecond value that is
140.64 + * an offset from the <a name="Epoch"><em>Epoch</em></a>, January 1, 1970
140.65 + * 00:00:00.000 GMT (Gregorian).
140.66 + *
140.67 + * <p>The class also provides additional fields and methods for
140.68 + * implementing a concrete calendar system outside the package. Those
140.69 + * fields and methods are defined as <code>protected</code>.
140.70 + *
140.71 + * <p>
140.72 + * Like other locale-sensitive classes, <code>Calendar</code> provides a
140.73 + * class method, <code>getInstance</code>, for getting a generally useful
140.74 + * object of this type. <code>Calendar</code>'s <code>getInstance</code> method
140.75 + * returns a <code>Calendar</code> object whose
140.76 + * calendar fields have been initialized with the current date and time:
140.77 + * <blockquote>
140.78 + * <pre>
140.79 + * Calendar rightNow = Calendar.getInstance();
140.80 + * </pre>
140.81 + * </blockquote>
140.82 + *
140.83 + * <p>A <code>Calendar</code> object can produce all the calendar field values
140.84 + * needed to implement the date-time formatting for a particular language and
140.85 + * calendar style (for example, Japanese-Gregorian, Japanese-Traditional).
140.86 + * <code>Calendar</code> defines the range of values returned by
140.87 + * certain calendar fields, as well as their meaning. For example,
140.88 + * the first month of the calendar system has value <code>MONTH ==
140.89 + * JANUARY</code> for all calendars. Other values are defined by the
140.90 + * concrete subclass, such as <code>ERA</code>. See individual field
140.91 + * documentation and subclass documentation for details.
140.92 + *
140.93 + * <h4>Getting and Setting Calendar Field Values</h4>
140.94 + *
140.95 + * <p>The calendar field values can be set by calling the <code>set</code>
140.96 + * methods. Any field values set in a <code>Calendar</code> will not be
140.97 + * interpreted until it needs to calculate its time value (milliseconds from
140.98 + * the Epoch) or values of the calendar fields. Calling the
140.99 + * <code>get</code>, <code>getTimeInMillis</code>, <code>getTime</code>,
140.100 + * <code>add</code> and <code>roll</code> involves such calculation.
140.101 + *
140.102 + * <h4>Leniency</h4>
140.103 + *
140.104 + * <p><code>Calendar</code> has two modes for interpreting the calendar
140.105 + * fields, <em>lenient</em> and <em>non-lenient</em>. When a
140.106 + * <code>Calendar</code> is in lenient mode, it accepts a wider range of
140.107 + * calendar field values than it produces. When a <code>Calendar</code>
140.108 + * recomputes calendar field values for return by <code>get()</code>, all of
140.109 + * the calendar fields are normalized. For example, a lenient
140.110 + * <code>GregorianCalendar</code> interprets <code>MONTH == JANUARY</code>,
140.111 + * <code>DAY_OF_MONTH == 32</code> as February 1.
140.112 +
140.113 + * <p>When a <code>Calendar</code> is in non-lenient mode, it throws an
140.114 + * exception if there is any inconsistency in its calendar fields. For
140.115 + * example, a <code>GregorianCalendar</code> always produces
140.116 + * <code>DAY_OF_MONTH</code> values between 1 and the length of the month. A
140.117 + * non-lenient <code>GregorianCalendar</code> throws an exception upon
140.118 + * calculating its time or calendar field values if any out-of-range field
140.119 + * value has been set.
140.120 + *
140.121 + * <h4><a name="first_week">First Week</a></h4>
140.122 + *
140.123 + * <code>Calendar</code> defines a locale-specific seven day week using two
140.124 + * parameters: the first day of the week and the minimal days in first week
140.125 + * (from 1 to 7). These numbers are taken from the locale resource data when a
140.126 + * <code>Calendar</code> is constructed. They may also be specified explicitly
140.127 + * through the methods for setting their values.
140.128 + *
140.129 + * <p>When setting or getting the <code>WEEK_OF_MONTH</code> or
140.130 + * <code>WEEK_OF_YEAR</code> fields, <code>Calendar</code> must determine the
140.131 + * first week of the month or year as a reference point. The first week of a
140.132 + * month or year is defined as the earliest seven day period beginning on
140.133 + * <code>getFirstDayOfWeek()</code> and containing at least
140.134 + * <code>getMinimalDaysInFirstWeek()</code> days of that month or year. Weeks
140.135 + * numbered ..., -1, 0 precede the first week; weeks numbered 2, 3,... follow
140.136 + * it. Note that the normalized numbering returned by <code>get()</code> may be
140.137 + * different. For example, a specific <code>Calendar</code> subclass may
140.138 + * designate the week before week 1 of a year as week <code><i>n</i></code> of
140.139 + * the previous year.
140.140 + *
140.141 + * <h4>Calendar Fields Resolution</h4>
140.142 + *
140.143 + * When computing a date and time from the calendar fields, there
140.144 + * may be insufficient information for the computation (such as only
140.145 + * year and month with no day of month), or there may be inconsistent
140.146 + * information (such as Tuesday, July 15, 1996 (Gregorian) -- July 15,
140.147 + * 1996 is actually a Monday). <code>Calendar</code> will resolve
140.148 + * calendar field values to determine the date and time in the
140.149 + * following way.
140.150 + *
140.151 + * <p>If there is any conflict in calendar field values,
140.152 + * <code>Calendar</code> gives priorities to calendar fields that have been set
140.153 + * more recently. The following are the default combinations of the
140.154 + * calendar fields. The most recent combination, as determined by the
140.155 + * most recently set single field, will be used.
140.156 + *
140.157 + * <p><a name="date_resolution">For the date fields</a>:
140.158 + * <blockquote>
140.159 + * <pre>
140.160 + * YEAR + MONTH + DAY_OF_MONTH
140.161 + * YEAR + MONTH + WEEK_OF_MONTH + DAY_OF_WEEK
140.162 + * YEAR + MONTH + DAY_OF_WEEK_IN_MONTH + DAY_OF_WEEK
140.163 + * YEAR + DAY_OF_YEAR
140.164 + * YEAR + DAY_OF_WEEK + WEEK_OF_YEAR
140.165 + * </pre></blockquote>
140.166 + *
140.167 + * <a name="time_resolution">For the time of day fields</a>:
140.168 + * <blockquote>
140.169 + * <pre>
140.170 + * HOUR_OF_DAY
140.171 + * AM_PM + HOUR
140.172 + * </pre></blockquote>
140.173 + *
140.174 + * <p>If there are any calendar fields whose values haven't been set in the selected
140.175 + * field combination, <code>Calendar</code> uses their default values. The default
140.176 + * value of each field may vary by concrete calendar systems. For example, in
140.177 + * <code>GregorianCalendar</code>, the default of a field is the same as that
140.178 + * of the start of the Epoch: i.e., <code>YEAR = 1970</code>, <code>MONTH =
140.179 + * JANUARY</code>, <code>DAY_OF_MONTH = 1</code>, etc.
140.180 + *
140.181 + * <p>
140.182 + * <strong>Note:</strong> There are certain possible ambiguities in
140.183 + * interpretation of certain singular times, which are resolved in the
140.184 + * following ways:
140.185 + * <ol>
140.186 + * <li> 23:59 is the last minute of the day and 00:00 is the first
140.187 + * minute of the next day. Thus, 23:59 on Dec 31, 1999 < 00:00 on
140.188 + * Jan 1, 2000 < 00:01 on Jan 1, 2000.
140.189 + *
140.190 + * <li> Although historically not precise, midnight also belongs to "am",
140.191 + * and noon belongs to "pm", so on the same day,
140.192 + * 12:00 am (midnight) < 12:01 am, and 12:00 pm (noon) < 12:01 pm
140.193 + * </ol>
140.194 + *
140.195 + * <p>
140.196 + * The date or time format strings are not part of the definition of a
140.197 + * calendar, as those must be modifiable or overridable by the user at
140.198 + * runtime. Use {@link DateFormat}
140.199 + * to format dates.
140.200 + *
140.201 + * <h4>Field Manipulation</h4>
140.202 + *
140.203 + * The calendar fields can be changed using three methods:
140.204 + * <code>set()</code>, <code>add()</code>, and <code>roll()</code>.</p>
140.205 + *
140.206 + * <p><strong><code>set(f, value)</code></strong> changes calendar field
140.207 + * <code>f</code> to <code>value</code>. In addition, it sets an
140.208 + * internal member variable to indicate that calendar field <code>f</code> has
140.209 + * been changed. Although calendar field <code>f</code> is changed immediately,
140.210 + * the calendar's time value in milliseconds is not recomputed until the next call to
140.211 + * <code>get()</code>, <code>getTime()</code>, <code>getTimeInMillis()</code>,
140.212 + * <code>add()</code>, or <code>roll()</code> is made. Thus, multiple calls to
140.213 + * <code>set()</code> do not trigger multiple, unnecessary
140.214 + * computations. As a result of changing a calendar field using
140.215 + * <code>set()</code>, other calendar fields may also change, depending on the
140.216 + * calendar field, the calendar field value, and the calendar system. In addition,
140.217 + * <code>get(f)</code> will not necessarily return <code>value</code> set by
140.218 + * the call to the <code>set</code> method
140.219 + * after the calendar fields have been recomputed. The specifics are determined by
140.220 + * the concrete calendar class.</p>
140.221 + *
140.222 + * <p><em>Example</em>: Consider a <code>GregorianCalendar</code>
140.223 + * originally set to August 31, 1999. Calling <code>set(Calendar.MONTH,
140.224 + * Calendar.SEPTEMBER)</code> sets the date to September 31,
140.225 + * 1999. This is a temporary internal representation that resolves to
140.226 + * October 1, 1999 if <code>getTime()</code>is then called. However, a
140.227 + * call to <code>set(Calendar.DAY_OF_MONTH, 30)</code> before the call to
140.228 + * <code>getTime()</code> sets the date to September 30, 1999, since
140.229 + * no recomputation occurs after <code>set()</code> itself.</p>
140.230 + *
140.231 + * <p><strong><code>add(f, delta)</code></strong> adds <code>delta</code>
140.232 + * to field <code>f</code>. This is equivalent to calling <code>set(f,
140.233 + * get(f) + delta)</code> with two adjustments:</p>
140.234 + *
140.235 + * <blockquote>
140.236 + * <p><strong>Add rule 1</strong>. The value of field <code>f</code>
140.237 + * after the call minus the value of field <code>f</code> before the
140.238 + * call is <code>delta</code>, modulo any overflow that has occurred in
140.239 + * field <code>f</code>. Overflow occurs when a field value exceeds its
140.240 + * range and, as a result, the next larger field is incremented or
140.241 + * decremented and the field value is adjusted back into its range.</p>
140.242 + *
140.243 + * <p><strong>Add rule 2</strong>. If a smaller field is expected to be
140.244 + * invariant, but it is impossible for it to be equal to its
140.245 + * prior value because of changes in its minimum or maximum after field
140.246 + * <code>f</code> is changed or other constraints, such as time zone
140.247 + * offset changes, then its value is adjusted to be as close
140.248 + * as possible to its expected value. A smaller field represents a
140.249 + * smaller unit of time. <code>HOUR</code> is a smaller field than
140.250 + * <code>DAY_OF_MONTH</code>. No adjustment is made to smaller fields
140.251 + * that are not expected to be invariant. The calendar system
140.252 + * determines what fields are expected to be invariant.</p>
140.253 + * </blockquote>
140.254 + *
140.255 + * <p>In addition, unlike <code>set()</code>, <code>add()</code> forces
140.256 + * an immediate recomputation of the calendar's milliseconds and all
140.257 + * fields.</p>
140.258 + *
140.259 + * <p><em>Example</em>: Consider a <code>GregorianCalendar</code>
140.260 + * originally set to August 31, 1999. Calling <code>add(Calendar.MONTH,
140.261 + * 13)</code> sets the calendar to September 30, 2000. <strong>Add rule
140.262 + * 1</strong> sets the <code>MONTH</code> field to September, since
140.263 + * adding 13 months to August gives September of the next year. Since
140.264 + * <code>DAY_OF_MONTH</code> cannot be 31 in September in a
140.265 + * <code>GregorianCalendar</code>, <strong>add rule 2</strong> sets the
140.266 + * <code>DAY_OF_MONTH</code> to 30, the closest possible value. Although
140.267 + * it is a smaller field, <code>DAY_OF_WEEK</code> is not adjusted by
140.268 + * rule 2, since it is expected to change when the month changes in a
140.269 + * <code>GregorianCalendar</code>.</p>
140.270 + *
140.271 + * <p><strong><code>roll(f, delta)</code></strong> adds
140.272 + * <code>delta</code> to field <code>f</code> without changing larger
140.273 + * fields. This is equivalent to calling <code>add(f, delta)</code> with
140.274 + * the following adjustment:</p>
140.275 + *
140.276 + * <blockquote>
140.277 + * <p><strong>Roll rule</strong>. Larger fields are unchanged after the
140.278 + * call. A larger field represents a larger unit of
140.279 + * time. <code>DAY_OF_MONTH</code> is a larger field than
140.280 + * <code>HOUR</code>.</p>
140.281 + * </blockquote>
140.282 + *
140.283 + * <p><em>Example</em>: See {@link java.util.GregorianCalendar#roll(int, int)}.
140.284 + *
140.285 + * <p><strong>Usage model</strong>. To motivate the behavior of
140.286 + * <code>add()</code> and <code>roll()</code>, consider a user interface
140.287 + * component with increment and decrement buttons for the month, day, and
140.288 + * year, and an underlying <code>GregorianCalendar</code>. If the
140.289 + * interface reads January 31, 1999 and the user presses the month
140.290 + * increment button, what should it read? If the underlying
140.291 + * implementation uses <code>set()</code>, it might read March 3, 1999. A
140.292 + * better result would be February 28, 1999. Furthermore, if the user
140.293 + * presses the month increment button again, it should read March 31,
140.294 + * 1999, not March 28, 1999. By saving the original date and using either
140.295 + * <code>add()</code> or <code>roll()</code>, depending on whether larger
140.296 + * fields should be affected, the user interface can behave as most users
140.297 + * will intuitively expect.</p>

140.310 + // ---------------------
140.311 +
140.312 + // The current time is represented in two ways by Calendar: as UTC
140.313 + // milliseconds from the epoch (1 January 1970 0:00 UTC), and as local
140.314 + // fields such as MONTH, HOUR, AM_PM, etc. It is possible to compute the
140.315 + // millis from the fields, and vice versa. The data needed to do this
140.316 + // conversion is encapsulated by a TimeZone object owned by the Calendar.
140.317 + // The data provided by the TimeZone object may also be overridden if the
140.318 + // user sets the ZONE_OFFSET and/or DST_OFFSET fields directly. The class
140.319 + // keeps track of what information was most recently set by the caller, and
140.320 + // uses that to compute any other information as needed.
140.321 +
140.322 + // If the user sets the fields using set(), the data flow is as follows.
140.323 + // This is implemented by the Calendar subclass's computeTime() method.
140.324 + // During this process, certain fields may be ignored. The disambiguation
140.325 + // algorithm for resolving which fields to pay attention to is described
140.326 + // in the class documentation.

141.50 + * The class is designed so that there's never more than one

141.53 + * the <code>getInstance</code> methods.
141.54 + * <p>
141.55 + * Users can supersede the Java runtime currency data by creating a properties
141.56 + * file named <code><JAVA_HOME>/lib/currency.properties</code>. The contents
141.57 + * of the properties file are key/value pairs of the ISO 3166 country codes
141.58 + * and the ISO 4217 currency data respectively. The value part consists of
141.59 + * three ISO 4217 values of a currency, i.e., an alphabetic code, a numeric
141.60 + * code, and a minor unit. Those three ISO 4217 values are separated by commas.
141.61 + * The lines which start with '#'s are considered comment lines. For example,
141.62 + * <p>
141.63 + * <code>

143.36 +/**
143.37 + * The class <code>Date</code> represents a specific instant
143.38 + * in time, with millisecond precision.
143.39 + * <p>
143.40 + * Prior to JDK 1.1, the class <code>Date</code> had two additional
143.41 + * functions. It allowed the interpretation of dates as year, month, day, hour,
143.42 + * minute, and second values. It also allowed the formatting and parsing
143.43 + * of date strings. Unfortunately, the API for these functions was not
143.44 + * amenable to internationalization. As of JDK 1.1, the
143.45 + * <code>Calendar</code> class should be used to convert between dates and time
143.46 + * fields and the <code>DateFormat</code> class should be used to format and
143.47 + * parse date strings.
143.48 + * The corresponding methods in <code>Date</code> are deprecated.
143.49 + * <p>
143.50 + * Although the <code>Date</code> class is intended to reflect
143.51 + * coordinated universal time (UTC), it may not do so exactly,
143.52 + * depending on the host environment of the Java Virtual Machine.
143.53 + * Nearly all modern operating systems assume that 1 day =
143.54 + * 24 × 60 × 60 = 86400 seconds
143.55 + * in all cases. In UTC, however, about once every year or two there
143.56 + * is an extra second, called a "leap second." The leap
143.57 + * second is always added as the last second of the day, and always
143.58 + * on December 31 or June 30. For example, the last minute of the
143.59 + * year 1995 was 61 seconds long, thanks to an added leap second.
143.60 + * Most computer clocks are not accurate enough to be able to reflect
143.61 + * the leap-second distinction.
143.62 + * <p>
143.63 + * Some computer standards are defined in terms of Greenwich mean
143.64 + * time (GMT), which is equivalent to universal time (UT). GMT is
143.65 + * the "civil" name for the standard; UT is the
143.66 + * "scientific" name for the same standard. The
143.67 + * distinction between UTC and UT is that UTC is based on an atomic
143.68 + * clock and UT is based on astronomical observations, which for all
143.69 + * practical purposes is an invisibly fine hair to split. Because the
143.70 + * earth's rotation is not uniform (it slows down and speeds up
143.71 + * in complicated ways), UT does not always flow uniformly. Leap
143.72 + * seconds are introduced as needed into UTC so as to keep UTC within
143.73 + * 0.9 seconds of UT1, which is a version of UT with certain
143.74 + * corrections applied. There are other time and date systems as
143.75 + * well; for example, the time scale used by the satellite-based
143.76 + * global positioning system (GPS) is synchronized to UTC but is
143.77 + * <i>not</i> adjusted for leap seconds. An interesting source of
143.78 + * further information is the U.S. Naval Observatory, particularly
143.79 + * the Directorate of Time at:
143.80 + * <blockquote><pre>
143.81 + * <a href=http://tycho.usno.navy.mil>http://tycho.usno.navy.mil</a>
143.82 + * </pre></blockquote>
143.83 + * <p>
143.84 + * and their definitions of "Systems of Time" at:
143.85 + * <blockquote><pre>
143.86 + * <a href=http://tycho.usno.navy.mil/systime.html>http://tycho.usno.navy.mil/systime.html</a>
143.87 + * </pre></blockquote>
143.88 + * <p>
143.89 + * In all methods of class <code>Date</code> that accept or return
143.90 + * year, month, date, hours, minutes, and seconds values, the
143.91 + * following representations are used:
143.92 + * <ul>
143.93 + * <li>A year <i>y</i> is represented by the integer
143.94 + * <i>y</i> <code>- 1900</code>.
143.95 + * <li>A month is represented by an integer from 0 to 11; 0 is January,
143.96 + * 1 is February, and so forth; thus 11 is December.
143.97 + * <li>A date (day of month) is represented by an integer from 1 to 31
143.98 + * in the usual manner.
143.99 + * <li>An hour is represented by an integer from 0 to 23. Thus, the hour
143.100 + * from midnight to 1 a.m. is hour 0, and the hour from noon to 1
143.101 + * p.m. is hour 12.
143.102 + * <li>A minute is represented by an integer from 0 to 59 in the usual manner.
143.103 + * <li>A second is represented by an integer from 0 to 61; the values 60 and
143.104 + * 61 occur only for leap seconds and even then only in Java
143.105 + * implementations that actually track leap seconds correctly. Because
143.106 + * of the manner in which leap seconds are currently introduced, it is
143.107 + * extremely unlikely that two leap seconds will occur in the same
143.108 + * minute, but this specification follows the date and time conventions
143.109 + * for ISO C.
143.110 + * </ul>
143.111 + * <p>
143.112 + * In all cases, arguments given to methods for these purposes need
143.113 + * not fall within the indicated ranges; for example, a date may be
143.114 + * specified as January 32 and is interpreted as meaning February 1.

143.346 + * meridian). If no time zone is specified, the local time zone is
143.347 + * assumed. GMT and UTC are considered equivalent.
143.348 + * <p>
143.349 + * The string <tt>s</tt> is processed from left to right, looking for
143.350 + * data of interest. Any material in <tt>s</tt> that is within the
143.351 + * ASCII parenthesis characters <tt>(</tt> and <tt>)</tt> is ignored.
143.352 + * Parentheses may be nested. Otherwise, the only characters permitted
143.353 + * within <tt>s</tt> are these ASCII characters:
143.354 + * <blockquote><pre>
143.355 + * abcdefghijklmnopqrstuvwxyz
143.356 + * ABCDEFGHIJKLMNOPQRSTUVWXYZ
143.357 + * 0123456789,+-:/</pre></blockquote>
143.358 + * and whitespace characters.<p>
143.359 + * A consecutive sequence of decimal digits is treated as a decimal
143.360 + * number:<ul>
143.361 + * <li>If a number is preceded by <tt>+</tt> or <tt>-</tt> and a year
143.362 + * has already been recognized, then the number is a time-zone
143.363 + * offset. If the number is less than 24, it is an offset measured
143.364 + * in hours. Otherwise, it is regarded as an offset in minutes,
143.365 + * expressed in 24-hour time format without punctuation. A
143.366 + * preceding <tt>-</tt> means a westward offset. Time zone offsets
143.367 + * are always relative to UTC (Greenwich). Thus, for example,
143.368 + * <tt>-5</tt> occurring in the string would mean "five hours west
143.369 + * of Greenwich" and <tt>+0430</tt> would mean "four hours and
143.370 + * thirty minutes east of Greenwich." It is permitted for the
143.371 + * string to specify <tt>GMT</tt>, <tt>UT</tt>, or <tt>UTC</tt>
143.372 + * redundantly-for example, <tt>GMT-5</tt> or <tt>utc+0430</tt>.
143.373 + * <li>The number is regarded as a year number if one of the
143.374 + * following conditions is true:
143.375 + * <ul>
143.376 + * <li>The number is equal to or greater than 70 and followed by a
143.377 + * space, comma, slash, or end of string
143.378 + * <li>The number is less than 70, and both a month and a day of
143.379 + * the month have already been recognized</li>
143.380 + * </ul>
143.381 + * If the recognized year number is less than 100, it is
143.382 + * interpreted as an abbreviated year relative to a century of
143.383 + * which dates are within 80 years before and 19 years after
143.384 + * the time when the Date class is initialized.
143.385 + * After adjusting the year number, 1900 is subtracted from
143.386 + * it. For example, if the current year is 1999 then years in
143.387 + * the range 19 to 99 are assumed to mean 1919 to 1999, while
143.388 + * years from 0 to 18 are assumed to mean 2000 to 2018. Note
143.389 + * that this is slightly different from the interpretation of
143.390 + * years less than 100 that is used in {@link java.text.SimpleDateFormat}.
143.391 + * <li>If the number is followed by a colon, it is regarded as an hour,
143.392 + * unless an hour has already been recognized, in which case it is
143.393 + * regarded as a minute.
143.394 + * <li>If the number is followed by a slash, it is regarded as a month
143.395 + * (it is decreased by 1 to produce a number in the range <tt>0</tt>
143.396 + * to <tt>11</tt>), unless a month has already been recognized, in
143.397 + * which case it is regarded as a day of the month.
143.398 + * <li>If the number is followed by whitespace, a comma, a hyphen, or
143.399 + * end of string, then if an hour has been recognized but not a
143.400 + * minute, it is regarded as a minute; otherwise, if a minute has
143.401 + * been recognized but not a second, it is regarded as a second;
143.402 + * otherwise, it is regarded as a day of the month. </ul><p>
143.403 + * A consecutive sequence of letters is regarded as a word and treated
143.404 + * as follows:<ul>
143.405 + * <li>A word that matches <tt>AM</tt>, ignoring case, is ignored (but
143.406 + * the parse fails if an hour has not been recognized or is less
143.407 + * than <tt>1</tt> or greater than <tt>12</tt>).
143.408 + * <li>A word that matches <tt>PM</tt>, ignoring case, adds <tt>12</tt>
143.409 + * to the hour (but the parse fails if an hour has not been
143.410 + * recognized or is less than <tt>1</tt> or greater than <tt>12</tt>).
143.411 + * <li>Any word that matches any prefix of <tt>SUNDAY, MONDAY, TUESDAY,
143.412 + * WEDNESDAY, THURSDAY, FRIDAY</tt>, or <tt>SATURDAY</tt>, ignoring
143.413 + * case, is ignored. For example, <tt>sat, Friday, TUE</tt>, and
143.414 + * <tt>Thurs</tt> are ignored.
143.415 + * <li>Otherwise, any word that matches any prefix of <tt>JANUARY,
143.416 + * FEBRUARY, MARCH, APRIL, MAY, JUNE, JULY, AUGUST, SEPTEMBER,
143.417 + * OCTOBER, NOVEMBER</tt>, or <tt>DECEMBER</tt>, ignoring case, and
143.418 + * considering them in the order given here, is recognized as
143.419 + * specifying a month and is converted to a number (<tt>0</tt> to
143.420 + * <tt>11</tt>). For example, <tt>aug, Sept, april</tt>, and
143.421 + * <tt>NOV</tt> are recognized as months. So is <tt>Ma</tt>, which
143.422 + * is recognized as <tt>MARCH</tt>, not <tt>MAY</tt>.
143.423 + * <li>Any word that matches <tt>GMT, UT</tt>, or <tt>UTC</tt>, ignoring
143.424 + * case, is treated as referring to UTC.
143.425 + * <li>Any word that matches <tt>EST, CST, MST</tt>, or <tt>PST</tt>,
143.426 + * ignoring case, is recognized as referring to the time zone in
143.427 + * North America that is five, six, seven, or eight hours west of
143.428 + * Greenwich, respectively. Any word that matches <tt>EDT, CDT,
143.429 + * MDT</tt>, or <tt>PDT</tt>, ignoring case, is recognized as

143.431 + * saving time.</ul><p>

144.34 +/**
144.35 + * A specialized {@link Map} implementation for use with enum type keys. All
144.36 + * of the keys in an enum map must come from a single enum type that is
144.37 + * specified, explicitly or implicitly, when the map is created. Enum maps
144.38 + * are represented internally as arrays. This representation is extremely
144.39 + * compact and efficient.
144.40 + *
144.41 + * <p>Enum maps are maintained in the <i>natural order</i> of their keys
144.42 + * (the order in which the enum constants are declared). This is reflected
144.43 + * in the iterators returned by the collections views ({@link #keySet()},
144.44 + * {@link #entrySet()}, and {@link #values()}).
144.45 + *
144.46 + * <p>Iterators returned by the collection views are <i>weakly consistent</i>:
144.47 + * they will never throw {@link ConcurrentModificationException} and they may
144.48 + * or may not show the effects of any modifications to the map that occur while
144.49 + * the iteration is in progress.
144.50 + *
144.51 + * <p>Null keys are not permitted. Attempts to insert a null key will
144.52 + * throw {@link NullPointerException}. Attempts to test for the
144.53 + * presence of a null key or to remove one will, however, function properly.
144.54 + * Null values are permitted.
144.55 +
144.56 + * <P>Like most collection implementations <tt>EnumMap</tt> is not
144.57 + * synchronized. If multiple threads access an enum map concurrently, and at
144.58 + * least one of the threads modifies the map, it should be synchronized
144.59 + * externally. This is typically accomplished by synchronizing on some
144.60 + * object that naturally encapsulates the enum map. If no such object exists,
144.61 + * the map should be "wrapped" using the {@link Collections#synchronizedMap}
144.62 + * method. This is best done at creation time, to prevent accidental
144.63 + * unsynchronized access:
144.64 + *
144.65 + * <pre>
144.66 + * Map<EnumKey, V> m
144.67 + * = Collections.synchronizedMap(new EnumMap<EnumKey, V>(...));
144.68 + * </pre>
144.69 + *
144.70 + * <p>Implementation note: All basic operations execute in constant time.
144.71 + * They are likely (though not guaranteed) to be faster than their
144.72 + * {@link HashMap} counterparts.
144.73 + *

145.33 +/**
145.34 + * A specialized {@link Set} implementation for use with enum types. All of
145.35 + * the elements in an enum set must come from a single enum type that is
145.36 + * specified, explicitly or implicitly, when the set is created. Enum sets
145.37 + * are represented internally as bit vectors. This representation is
145.38 + * extremely compact and efficient. The space and time performance of this
145.39 + * class should be good enough to allow its use as a high-quality, typesafe
145.40 + * alternative to traditional <tt>int</tt>-based "bit flags." Even bulk
145.41 + * operations (such as <tt>containsAll</tt> and <tt>retainAll</tt>) should
145.42 + * run very quickly if their argument is also an enum set.
145.43 + *
145.44 + * <p>The iterator returned by the <tt>iterator</tt> method traverses the
145.45 + * elements in their <i>natural order</i> (the order in which the enum
145.46 + * constants are declared). The returned iterator is <i>weakly
145.47 + * consistent</i>: it will never throw {@link ConcurrentModificationException}
145.48 + * and it may or may not show the effects of any modifications to the set that
145.49 + * occur while the iteration is in progress.
145.50 + *
145.51 + * <p>Null elements are not permitted. Attempts to insert a null element
145.52 + * will throw {@link NullPointerException}. Attempts to test for the
145.53 + * presence of a null element or to remove one will, however, function
145.54 + * properly.
145.55 + *
145.56 + * <P>Like most collection implementations, <tt>EnumSet</tt> is not
145.57 + * synchronized. If multiple threads access an enum set concurrently, and at
145.58 + * least one of the threads modifies the set, it should be synchronized
145.59 + * externally. This is typically accomplished by synchronizing on some
145.60 + * object that naturally encapsulates the enum set. If no such object exists,
145.61 + * the set should be "wrapped" using the {@link Collections#synchronizedSet}
145.62 + * method. This is best done at creation time, to prevent accidental
145.63 + * unsynchronized access:
145.64 + *
145.65 + * <pre>
145.66 + * Set<MyEnum> s = Collections.synchronizedSet(EnumSet.noneOf(MyEnum.class));
145.67 + * </pre>
145.68 + *
145.69 + * <p>Implementation note: All basic operations execute in constant time.
145.70 + * They are likely (though not guaranteed) to be much faster than their
145.71 + * {@link HashSet} counterparts. Even bulk operations execute in
145.72 + * constant time if their argument is also an enum set.

147.53 + * A <code>Locale</code> object represents a specific geographical, political,
147.54 + * or cultural region. An operation that requires a <code>Locale</code> to perform
147.55 + * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code>
147.56 + * to tailor information for the user. For example, displaying a number
147.57 + * is a locale-sensitive operation— the number should be formatted
147.58 + * according to the customs and conventions of the user's native country,
147.59 + * region, or culture.
147.60 + *
147.61 + * <p> The <code>Locale</code> class implements identifiers
147.62 + * interchangeable with BCP 47 (IETF BCP 47, "Tags for Identifying

147.155 + * extension keys and values to lower case. Note that extensions
147.156 + * cannot have empty values.</dd><br>

147.161 + * <code>SUBTAG = [0-9a-zA-Z]{1,8}</code> and for other keys
147.162 + * <code>SUBTAG = [0-9a-zA-Z]{2,8}</code> (that is, 'x' allows

147.168 + *
147.169 + * <b>Note:</b> Although BCP 47 requires field values to be registered
147.170 + * in the IANA Language Subtag Registry, the <code>Locale</code> class
147.171 + * does not provide any validation features. The <code>Builder</code>
147.172 + * only checks if an individual field satisfies the syntactic
147.173 + * requirement (is well-formed), but does not validate the value
147.174 + * itself. See {@link Builder} for details.
147.175 + *
147.176 + * <h4><a name="def_locale_extension">Unicode locale/language extension</h4>
147.177 + *
147.178 + * <p>UTS#35, "Unicode Locale Data Markup Language" defines optional
147.179 + * attributes and keywords to override or refine the default behavior
147.180 + * associated with a locale. A keyword is represented by a pair of
147.181 + * key and type. For example, "nu-thai" indicates that Thai local
147.182 + * digits (value:"thai") should be used for formatting numbers
147.183 + * (key:"nu").
147.184 + *
147.185 + * <p>The keywords are mapped to a BCP 47 extension value using the
147.186 + * extension key 'u' ({@link #UNICODE_LOCALE_EXTENSION}). The above
147.187 + * example, "nu-thai", becomes the extension "u-nu-thai".code
147.188 + *
147.189 + * <p>Thus, when a <code>Locale</code> object contains Unicode locale
147.190 + * attributes and keywords,
147.191 + * <code>getExtension(UNICODE_LOCALE_EXTENSION)</code> will return a
147.192 + * String representing this information, for example, "nu-thai". The
147.193 + * <code>Locale</code> class also provides {@link
147.194 + * #getUnicodeLocaleAttributes}, {@link #getUnicodeLocaleKeys}, and
147.195 + * {@link #getUnicodeLocaleType} which allow you to access Unicode
147.196 + * locale attributes and key/type pairs directly. When represented as
147.197 + * a string, the Unicode Locale Extension lists attributes
147.198 + * alphabetically, followed by key/type sequences with keys listed
147.199 + * alphabetically (the order of subtags comprising a key's type is
147.200 + * fixed when the type is defined)
147.201 + *
147.202 + * <p>A well-formed locale key has the form
147.203 + * <code>[0-9a-zA-Z]{2}</code>. A well-formed locale type has the
147.204 + * form <code>"" | [0-9a-zA-Z]{3,8} ('-' [0-9a-zA-Z]{3,8})*</code> (it
147.205 + * can be empty, or a series of subtags 3-8 alphanums in length). A
147.206 + * well-formed locale attribute has the form
147.207 + * <code>[0-9a-zA-Z]{3,8}</code> (it is a single subtag with the same
147.208 + * form as a locale type subtag).
147.209 + *
147.210 + * <p>The Unicode locale extension specifies optional behavior in
147.211 + * locale-sensitive services. Although the LDML specification defines
147.212 + * various keys and values, actual locale-sensitive service
147.213 + * implementations in a Java Runtime Environment might not support any
147.214 + * particular Unicode locale attributes or key/type pairs.
147.215 + *
147.216 + * <h4>Creating a Locale</h4>
147.217 + *
147.218 + * <p>There are several different ways to create a <code>Locale</code>
147.219 + * object.
147.220 + *
147.221 + * <h5>Builder</h5>
147.222 + *
147.223 + * <p>Using {@link Builder} you can construct a <code>Locale</code> object
147.224 + * that conforms to BCP 47 syntax.
147.225 + *
147.226 + * <h5>Constructors</h5>
147.227 + *
147.228 + * <p>The <code>Locale</code> class provides three constructors:
147.229 + * <blockquote>
147.230 + * <pre>
147.231 + * {@link #Locale(String language)}
147.232 + * {@link #Locale(String language, String country)}
147.233 + * {@link #Locale(String language, String country, String variant)}
147.234 + * </pre>
147.235 + * </blockquote>
147.236 + * These constructors allow you to create a <code>Locale</code> object
147.237 + * with language, country and variant, but you cannot specify
147.238 + * script or extensions.
147.239 + *
147.240 + * <h5>Factory Methods</h5>
147.241 + *
147.242 + * <p>The method {@link #forLanguageTag} creates a <code>Locale</code>
147.243 + * object for a well-formed BCP 47 language tag.
147.244 + *
147.245 + * <h5>Locale Constants</h5>
147.246 + *
147.247 + * <p>The <code>Locale</code> class provides a number of convenient constants
147.248 + * that you can use to create <code>Locale</code> objects for commonly used
147.249 + * locales. For example, the following creates a <code>Locale</code> object
147.250 + * for the United States:
147.251 + * <blockquote>
147.252 + * <pre>
147.253 + * Locale.US
147.254 + * </pre>
147.255 + * </blockquote>
147.256 + *
147.257 + * <h4>Use of Locale</h4>
147.258 + *
147.259 + * <p>Once you've created a <code>Locale</code> you can query it for information
147.260 + * about itself. Use <code>getCountry</code> to get the country (or region)
147.261 + * code and <code>getLanguage</code> to get the language code.
147.262 + * You can use <code>getDisplayCountry</code> to get the
147.263 + * name of the country suitable for displaying to the user. Similarly,
147.264 + * you can use <code>getDisplayLanguage</code> to get the name of
147.265 + * the language suitable for displaying to the user. Interestingly,
147.266 + * the <code>getDisplayXXX</code> methods are themselves locale-sensitive
147.267 + * and have two versions: one that uses the default locale and one
147.268 + * that uses the locale specified as an argument.
147.269 + *
147.270 + * <p>The Java Platform provides a number of classes that perform locale-sensitive
147.271 + * operations. For example, the <code>NumberFormat</code> class formats
147.272 + * numbers, currency, and percentages in a locale-sensitive manner. Classes
147.273 + * such as <code>NumberFormat</code> have several convenience methods
147.274 + * for creating a default object of that type. For example, the
147.275 + * <code>NumberFormat</code> class provides these three convenience methods
147.276 + * for creating a default <code>NumberFormat</code> object:
147.277 + * <blockquote>
147.278 + * <pre>
147.279 + * NumberFormat.getInstance()
147.280 + * NumberFormat.getCurrencyInstance()
147.281 + * NumberFormat.getPercentInstance()
147.282 + * </pre>
147.283 + * </blockquote>
147.284 + * Each of these methods has two variants; one with an explicit locale
147.285 + * and one without; the latter uses the default locale:
147.286 + * <blockquote>
147.287 + * <pre>
147.288 + * NumberFormat.getInstance(myLocale)
147.289 + * NumberFormat.getCurrencyInstance(myLocale)
147.290 + * NumberFormat.getPercentInstance(myLocale)
147.291 + * </pre>
147.292 + * </blockquote>
147.293 + * A <code>Locale</code> is the mechanism for identifying the kind of object
147.294 + * (<code>NumberFormat</code>) that you would like to get. The locale is
147.295 + * <STRONG>just</STRONG> a mechanism for identifying objects,
147.296 + * <STRONG>not</STRONG> a container for the objects themselves.
147.297 + *
147.298 + * <h4>Compatibility</h4>
147.299 + *
147.300 + * <p>In order to maintain compatibility with existing usage, Locale's
147.301 + * constructors retain their behavior prior to the Java Runtime
147.302 + * Environment version 1.7. The same is largely true for the
147.303 + * <code>toString</code> method. Thus Locale objects can continue to
147.304 + * be used as they were. In particular, clients who parse the output
147.305 + * of toString into language, country, and variant fields can continue
147.306 + * to do so (although this is strongly discouraged), although the
147.307 + * variant field will have additional information in it if script or
147.308 + * extensions are present.
147.309 + *
147.310 + * <p>In addition, BCP 47 imposes syntax restrictions that are not
147.311 + * imposed by Locale's constructors. This means that conversions
147.312 + * between some Locales and BCP 47 language tags cannot be made without
147.313 + * losing information. Thus <code>toLanguageTag</code> cannot
147.314 + * represent the state of locales whose language, country, or variant
147.315 + * do not conform to BCP 47.
147.316 + *
147.317 + * <p>Because of these issues, it is recommended that clients migrate
147.318 + * away from constructing non-conforming locales and use the
147.319 + * <code>forLanguageTag</code> and <code>Locale.Builder</code> APIs instead.
147.320 + * Clients desiring a string representation of the complete locale can
147.321 + * then always rely on <code>toLanguageTag</code> for this purpose.
147.322 + *
147.323 + * <h5><a name="special_cases_constructor"/>Special cases</h5>
147.324 + *
147.325 + * <p>For compatibility reasons, two
147.326 + * non-conforming locales are treated as special cases. These are
147.327 + * <b><tt>ja_JP_JP</tt></b> and <b><tt>th_TH_TH</tt></b>. These are ill-formed
147.328 + * in BCP 47 since the variants are too short. To ease migration to BCP 47,
147.329 + * these are treated specially during construction. These two cases (and only
147.330 + * these) cause a constructor to generate an extension, all other values behave
147.331 + * exactly as they did prior to Java 7.
147.332 + *
147.333 + * <p>Java has used <tt>ja_JP_JP</tt> to represent Japanese as used in
147.334 + * Japan together with the Japanese Imperial calendar. This is now
147.335 + * representable using a Unicode locale extension, by specifying the
147.336 + * Unicode locale key <tt>ca</tt> (for "calendar") and type
147.337 + * <tt>japanese</tt>. When the Locale constructor is called with the
147.338 + * arguments "ja", "JP", "JP", the extension "u-ca-japanese" is
147.339 + * automatically added.
147.340 + *
147.341 + * <p>Java has used <tt>th_TH_TH</tt> to represent Thai as used in
147.342 + * Thailand together with Thai digits. This is also now representable using
147.343 + * a Unicode locale extension, by specifying the Unicode locale key
147.344 + * <tt>nu</tt> (for "number") and value <tt>thai</tt>. When the Locale
147.345 + * constructor is called with the arguments "th", "TH", "TH", the
147.346 + * extension "u-nu-thai" is automatically added.
147.347 + *
147.348 + * <h5>Serialization</h5>
147.349 + *
147.350 + * <p>During serialization, writeObject writes all fields to the output
147.351 + * stream, including extensions.
147.352 + *
147.353 + * <p>During deserialization, readResolve adds extensions as described
147.354 + * in <a href="#special_cases_constructor">Special Cases</a>, only
147.355 + * for the two cases th_TH_TH and ja_JP_JP.
147.356 + *
147.357 + * <h5>Legacy language codes</h5>
147.358 + *
147.359 + * <p>Locale's constructor has always converted three language codes to
147.360 + * their earlier, obsoleted forms: <tt>he</tt> maps to <tt>iw</tt>,
147.361 + * <tt>yi</tt> maps to <tt>ji</tt>, and <tt>id</tt> maps to
147.362 + * <tt>in</tt>. This continues to be the case, in order to not break
147.363 + * backwards compatibility.
147.364 + *
147.365 + * <p>The APIs added in 1.7 map between the old and new language codes,
147.366 + * maintaining the old codes internal to Locale (so that
147.367 + * <code>getLanguage</code> and <code>toString</code> reflect the old
147.368 + * code), but using the new codes in the BCP 47 language tag APIs (so
147.369 + * that <code>toLanguageTag</code> reflects the new one). This
147.370 + * preserves the equivalence between Locales no matter which code or
147.371 + * API is used to construct them. Java's default resource bundle
147.372 + * lookup mechanism also implements this mapping, so that resources
147.373 + * can be named using either convention, see {@link ResourceBundle.Control}.
147.374 + *
147.375 + * <h5>Three-letter language/country(region) codes</h5>
147.376 + *
147.377 + * <p>The Locale constructors have always specified that the language
147.378 + * and the country param be two characters in length, although in
147.379 + * practice they have accepted any length. The specification has now
147.380 + * been relaxed to allow language codes of two to eight characters and
147.381 + * country (region) codes of two to three characters, and in
147.382 + * particular, three-letter language codes and three-digit region
147.383 + * codes as specified in the IANA Language Subtag Registry. For
147.384 + * compatibility, the implementation still does not impose a length
147.385 + * constraint.

149.47 + * A property list can contain another property list as its

149.57 + * on a "compromised" <code>Properties</code> object that contains a

149.70 + * {@link #store(java.io.OutputStream, java.lang.String) store(OutputStream, String)}
149.71 + * methods work the same way as the load(Reader)/store(Writer, String) pair, except
149.72 + * the input/output stream is encoded in ISO 8859-1 character encoding.
149.73 + * Characters that cannot be directly represented in this encoding can be written using
149.74 + * Unicode escapes as defined in section 3.3 of
149.75 + * <cite>The Java™ Language Specification</cite>;
149.76 + * only a single 'u' character is allowed in an escape
149.77 + * sequence. The native2ascii tool can be used to convert property files to and
149.78 + * from other character encodings.
149.79 + *
149.80 + * <p> The {@link #loadFromXML(InputStream)} and {@link

149.82 + * in a simple XML format. By default the UTF-8 character encoding is used,

149.169 + * Reads a property list (key and element pairs) from the input
149.170 + * character stream in a simple line-oriented format.
149.171 + * <p>
149.172 + * Properties are processed in terms of lines. There are two
149.173 + * kinds of line, <i>natural lines</i> and <i>logical lines</i>.
149.174 + * A natural line is defined as a line of
149.175 + * characters that is terminated either by a set of line terminator
149.176 + * characters (<code>\n</code> or <code>\r</code> or <code>\r\n</code>)
149.177 + * or by the end of the stream. A natural line may be either a blank line,
149.178 + * a comment line, or hold all or some of a key-element pair. A logical
149.179 + * line holds all the data of a key-element pair, which may be spread
149.180 + * out across several adjacent natural lines by escaping
149.181 + * the line terminator sequence with a backslash character
149.182 + * <code>\</code>. Note that a comment line cannot be extended
149.183 + * in this manner; every natural line that is a comment must have
149.184 + * its own comment indicator, as described below. Lines are read from
149.185 + * input until the end of the stream is reached.
149.186 + *
149.187 + * <p>
149.188 + * A natural line that contains only white space characters is
149.189 + * considered blank and is ignored. A comment line has an ASCII
149.190 + * <code>'#'</code> or <code>'!'</code> as its first non-white
149.191 + * space character; comment lines are also ignored and do not
149.192 + * encode key-element information. In addition to line
149.193 + * terminators, this format considers the characters space
149.194 + * (<code>' '</code>, <code>'\u0020'</code>), tab
149.195 + * (<code>'\t'</code>, <code>'\u0009'</code>), and form feed
149.196 + * (<code>'\f'</code>, <code>'\u000C'</code>) to be white
149.197 + * space.
149.198 + *
149.199 + * <p>
149.200 + * If a logical line is spread across several natural lines, the
149.201 + * backslash escaping the line terminator sequence, the line
149.202 + * terminator sequence, and any white space at the start of the
149.203 + * following line have no affect on the key or element values.
149.204 + * The remainder of the discussion of key and element parsing
149.205 + * (when loading) will assume all the characters constituting
149.206 + * the key and element appear on a single natural line after
149.207 + * line continuation characters have been removed. Note that
149.208 + * it is <i>not</i> sufficient to only examine the character
149.209 + * preceding a line terminator sequence to decide if the line
149.210 + * terminator is escaped; there must be an odd number of
149.211 + * contiguous backslashes for the line terminator to be escaped.
149.212 + * Since the input is processed from left to right, a
149.213 + * non-zero even number of 2<i>n</i> contiguous backslashes
149.214 + * before a line terminator (or elsewhere) encodes <i>n</i>
149.215 + * backslashes after escape processing.
149.216 + *
149.217 + * <p>
149.218 + * The key contains all of the characters in the line starting
149.219 + * with the first non-white space character and up to, but not
149.220 + * including, the first unescaped <code>'='</code>,
149.221 + * <code>':'</code>, or white space character other than a line
149.222 + * terminator. All of these key termination characters may be
149.223 + * included in the key by escaping them with a preceding backslash
149.224 + * character; for example,<p>
149.225 + *
149.226 + * <code>\:\=</code><p>
149.227 + *
149.228 + * would be the two-character key <code>":="</code>. Line
149.229 + * terminator characters can be included using <code>\r</code> and
149.230 + * <code>\n</code> escape sequences. Any white space after the
149.231 + * key is skipped; if the first non-white space character after
149.232 + * the key is <code>'='</code> or <code>':'</code>, then it is
149.233 + * ignored and any white space characters after it are also
149.234 + * skipped. All remaining characters on the line become part of
149.235 + * the associated element string; if there are no remaining
149.236 + * characters, the element is the empty string
149.237 + * <code>""</code>. Once the raw character sequences
149.238 + * constituting the key and element are identified, escape
149.239 + * processing is performed as described above.
149.240 + *
149.241 + * <p>
149.242 + * As an example, each of the following three lines specifies the key
149.243 + * <code>"Truth"</code> and the associated element value
149.244 + * <code>"Beauty"</code>:
149.245 + * <p>
149.246 + * <pre>
149.247 + * Truth = Beauty
149.248 + * Truth:Beauty
149.249 + * Truth :Beauty
149.250 + * </pre>
149.251 + * As another example, the following three lines specify a single
149.252 + * property:
149.253 + * <p>
149.254 + * <pre>
149.255 + * fruits apple, banana, pear, \
149.256 + * cantaloupe, watermelon, \

149.277 + * Characters in keys and elements can be represented in escape
149.278 + * sequences similar to those used for character and string literals
149.279 + * (see sections 3.3 and 3.10.6 of
149.280 + * <cite>The Java™ Language Specification</cite>).
149.281 + *
149.282 + * The differences from the character escape sequences and Unicode
149.283 + * escapes used for characters and strings are:
149.284 + *
149.285 + * <ul>
149.286 + * <li> Octal escapes are not recognized.
149.287 + *
149.288 + * <li> The character sequence <code>\b</code> does <i>not</i>
149.289 + * represent a backspace character.
149.290 + *
149.291 + * <li> The method does not treat a backslash character,
149.292 + * <code>\</code>, before a non-valid escape character as an
149.293 + * error; the backslash is silently dropped. For example, in a
149.294 + * Java string the sequence <code>"\z"</code> would cause a
149.295 + * compile time error. In contrast, this method silently drops
149.296 + * the backslash. Therefore, this method treats the two character
149.297 + * sequence <code>"\b"</code> as equivalent to the single
149.298 + * character <code>'b'</code>.
149.299 + *
149.300 + * <li> Escapes are not necessary for single and double quotes;
149.301 + * however, by the rule above, single and double quote characters
149.302 + * preceded by a backslash still yield single and double quote
149.303 + * characters, respectively.
149.304 + *
149.305 + * <li> Only a single 'u' character is allowed in a Uniocde escape
149.306 + * sequence.
149.307 + *

149.746 + * element, leading space characters, but not embedded or trailing
149.747 + * space characters, are written with a preceding <code>\</code>

150.50 + * <code>PropertyResourceBundle</code> is a concrete subclass of
150.51 + * <code>ResourceBundle</code> that manages resources for a locale
150.52 + * using a set of static strings from a property file. See
150.53 + * {@link ResourceBundle ResourceBundle} for more information about resource
150.54 + * bundles.
150.55 + *
150.56 + * <p>
150.57 + * Unlike other types of resource bundle, you don't subclass
150.58 + * <code>PropertyResourceBundle</code>. Instead, you supply properties
150.59 + * files containing the resource data. <code>ResourceBundle.getBundle</code>
150.60 + * will automatically look for the appropriate properties file and create a
150.61 + * <code>PropertyResourceBundle</code> that refers to it. See
150.62 + * {@link ResourceBundle#getBundle(java.lang.String, java.util.Locale, java.lang.ClassLoader) ResourceBundle.getBundle}
150.63 + * for a complete description of the search and instantiation strategy.
150.64 + *
150.65 + * <p>
150.66 + * The following <a name="sample">example</a> shows a member of a resource
150.67 + * bundle family with the base name "MyResources".
150.68 + * The text defines the bundle "MyResources_de",
150.69 + * the German member of the bundle family.
150.70 + * This member is based on <code>PropertyResourceBundle</code>, and the text
150.71 + * therefore is the content of the file "MyResources_de.properties"
150.72 + * (a related <a href="ListResourceBundle.html#sample">example</a> shows
150.73 + * how you can add bundles to this family that are implemented as subclasses
150.74 + * of <code>ListResourceBundle</code>).
150.75 + * The keys in this example are of the form "s1" etc. The actual
150.76 + * keys are entirely up to your choice, so long as they are the same as
150.77 + * the keys you use in your program to retrieve the objects from the bundle.
150.78 + * Keys are case-sensitive.
150.79 + * <blockquote>
150.80 + * <pre>
150.81 + * # MessageFormat pattern
150.82 + * s1=Die Platte \"{1}\" enthält {0}.
150.83 + *

152.54 +/**
152.55 + *
152.56 + * Resource bundles contain locale-specific objects. When your program needs a
152.57 + * locale-specific resource, a <code>String</code> for example, your program can
152.58 + * load it from the resource bundle that is appropriate for the current user's
152.59 + * locale. In this way, you can write program code that is largely independent
152.60 + * of the user's locale isolating most, if not all, of the locale-specific
152.61 + * information in resource bundles.
152.62 + *
152.63 + * <p>
152.64 + * This allows you to write programs that can:
152.65 + * <UL type=SQUARE>
152.66 + * <LI> be easily localized, or translated, into different languages
152.67 + * <LI> handle multiple locales at once
152.68 + * <LI> be easily modified later to support even more locales
152.69 + * </UL>
152.70 + *
152.71 + * <P>
152.72 + * Resource bundles belong to families whose members share a common base
152.73 + * name, but whose names also have additional components that identify
152.74 + * their locales. For example, the base name of a family of resource
152.75 + * bundles might be "MyResources". The family should have a default
152.76 + * resource bundle which simply has the same name as its family -
152.77 + * "MyResources" - and will be used as the bundle of last resort if a
152.78 + * specific locale is not supported. The family can then provide as
152.79 + * many locale-specific members as needed, for example a German one
152.80 + * named "MyResources_de".
152.81 + *
152.82 + * <P>
152.83 + * Each resource bundle in a family contains the same items, but the items have
152.84 + * been translated for the locale represented by that resource bundle.
152.85 + * For example, both "MyResources" and "MyResources_de" may have a
152.86 + * <code>String</code> that's used on a button for canceling operations.
152.87 + * In "MyResources" the <code>String</code> may contain "Cancel" and in
152.88 + * "MyResources_de" it may contain "Abbrechen".
152.89 + *
152.90 + * <P>
152.91 + * If there are different resources for different countries, you
152.92 + * can make specializations: for example, "MyResources_de_CH" contains objects for
152.93 + * the German language (de) in Switzerland (CH). If you want to only
152.94 + * modify some of the resources
152.95 + * in the specialization, you can do so.
152.96 + *
152.97 + * <P>
152.98 + * When your program needs a locale-specific object, it loads
152.99 + * the <code>ResourceBundle</code> class using the
152.100 + * {@link #getBundle(java.lang.String, java.util.Locale) getBundle}
152.101 + * method:
152.102 + * <blockquote>
152.103 + * <pre>
152.104 + * ResourceBundle myResources =
152.105 + * ResourceBundle.getBundle("MyResources", currentLocale);
152.106 + * </pre>
152.107 + * </blockquote>
152.108 + *
152.109 + * <P>
152.110 + * Resource bundles contain key/value pairs. The keys uniquely
152.111 + * identify a locale-specific object in the bundle. Here's an
152.112 + * example of a <code>ListResourceBundle</code> that contains
152.113 + * two key/value pairs:
152.114 + * <blockquote>
152.115 + * <pre>
152.116 + * public class MyResources extends ListResourceBundle {
152.117 + * protected Object[][] getContents() {
152.118 + * return new Object[][] {
152.119 + * // LOCALIZE THE SECOND STRING OF EACH ARRAY (e.g., "OK")
152.120 + * {"OkKey", "OK"},
152.121 + * {"CancelKey", "Cancel"},
152.122 + * // END OF MATERIAL TO LOCALIZE
152.123 + * };
152.124 + * }
152.125 + * }
152.126 + * </pre>
152.127 + * </blockquote>
152.128 + * Keys are always <code>String</code>s.
152.129 + * In this example, the keys are "OkKey" and "CancelKey".
152.130 + * In the above example, the values
152.131 + * are also <code>String</code>s--"OK" and "Cancel"--but
152.132 + * they don't have to be. The values can be any type of object.
152.133 + *
152.134 + * <P>
152.135 + * You retrieve an object from resource bundle using the appropriate
152.136 + * getter method. Because "OkKey" and "CancelKey"
152.137 + * are both strings, you would use <code>getString</code> to retrieve them:
152.138 + * <blockquote>
152.139 + * <pre>
152.140 + * button1 = new Button(myResources.getString("OkKey"));
152.141 + * button2 = new Button(myResources.getString("CancelKey"));
152.142 + * </pre>
152.143 + * </blockquote>
152.144 + * The getter methods all require the key as an argument and return
152.145 + * the object if found. If the object is not found, the getter method
152.146 + * throws a <code>MissingResourceException</code>.
152.147 + *
152.148 + * <P>
152.149 + * Besides <code>getString</code>, <code>ResourceBundle</code> also provides
152.150 + * a method for getting string arrays, <code>getStringArray</code>,
152.151 + * as well as a generic <code>getObject</code> method for any other
152.152 + * type of object. When using <code>getObject</code>, you'll
152.153 + * have to cast the result to the appropriate type. For example:
152.154 + * <blockquote>
152.155 + * <pre>
152.156 + * int[] myIntegers = (int[]) myResources.getObject("intList");
152.157 + * </pre>
152.158 + * </blockquote>
152.159 + *
152.160 + * <P>
152.161 + * The Java Platform provides two subclasses of <code>ResourceBundle</code>,
152.162 + * <code>ListResourceBundle</code> and <code>PropertyResourceBundle</code>,
152.163 + * that provide a fairly simple way to create resources.
152.164 + * As you saw briefly in a previous example, <code>ListResourceBundle</code>
152.165 + * manages its resource as a list of key/value pairs.
152.166 + * <code>PropertyResourceBundle</code> uses a properties file to manage
152.167 + * its resources.
152.168 + *
152.169 + * <p>
152.170 + * If <code>ListResourceBundle</code> or <code>PropertyResourceBundle</code>
152.171 + * do not suit your needs, you can write your own <code>ResourceBundle</code>
152.172 + * subclass. Your subclasses must override two methods: <code>handleGetObject</code>
152.173 + * and <code>getKeys()</code>.
152.174 + *
152.175 + * <h4>ResourceBundle.Control</h4>
152.176 + *
152.177 + * The {@link ResourceBundle.Control} class provides information necessary
152.178 + * to perform the bundle loading process by the <code>getBundle</code>
152.179 + * factory methods that take a <code>ResourceBundle.Control</code>
152.180 + * instance. You can implement your own subclass in order to enable
152.181 + * non-standard resource bundle formats, change the search strategy, or
152.182 + * define caching parameters. Refer to the descriptions of the class and the
152.183 + * {@link #getBundle(String, Locale, ClassLoader, Control) getBundle}
152.184 + * factory method for details.
152.185 + *
152.186 + * <h4>Cache Management</h4>
152.187 + *
152.188 + * Resource bundle instances created by the <code>getBundle</code> factory
152.189 + * methods are cached by default, and the factory methods return the same
152.190 + * resource bundle instance multiple times if it has been
152.191 + * cached. <code>getBundle</code> clients may clear the cache, manage the
152.192 + * lifetime of cached resource bundle instances using time-to-live values,
152.193 + * or specify not to cache resource bundle instances. Refer to the
152.194 + * descriptions of the {@linkplain #getBundle(String, Locale, ClassLoader,
152.195 + * Control) <code>getBundle</code> factory method}, {@link
152.196 + * #clearCache(ClassLoader) clearCache}, {@link
152.197 + * Control#getTimeToLive(String, Locale)
152.198 + * ResourceBundle.Control.getTimeToLive}, and {@link
152.199 + * Control#needsReload(String, Locale, String, ClassLoader, ResourceBundle,
152.200 + * long) ResourceBundle.Control.needsReload} for details.
152.201 + *
152.202 + * <h4>Example</h4>
152.203 + *
152.204 + * The following is a very simple example of a <code>ResourceBundle</code>
152.205 + * subclass, <code>MyResources</code>, that manages two resources (for a larger number of
152.206 + * resources you would probably use a <code>Map</code>).
152.207 + * Notice that you don't need to supply a value if
152.208 + * a "parent-level" <code>ResourceBundle</code> handles the same
152.209 + * key with the same value (as for the okKey below).
152.210 + * <blockquote>
152.211 + * <pre>
152.212 + * // default (English language, United States)
152.213 + * public class MyResources extends ResourceBundle {
152.214 + * public Object handleGetObject(String key) {
152.215 + * if (key.equals("okKey")) return "Ok";
152.216 + * if (key.equals("cancelKey")) return "Cancel";
152.217 + * return null;
152.218 + * }
152.219 + *
152.220 + * public Enumeration<String> getKeys() {
152.221 + * return Collections.enumeration(keySet());
152.222 + * }
152.223 + *
152.224 + * // Overrides handleKeySet() so that the getKeys() implementation
152.225 + * // can rely on the keySet() value.
152.226 + * protected Set<String> handleKeySet() {
152.227 + * return new HashSet<String>(Arrays.asList("okKey", "cancelKey"));
152.228 + * }
152.229 + * }
152.230 + *
152.231 + * // German language
152.232 + * public class MyResources_de extends MyResources {
152.233 + * public Object handleGetObject(String key) {
152.234 + * // don't need okKey, since parent level handles it.
152.235 + * if (key.equals("cancelKey")) return "Abbrechen";
152.236 + * return null;
152.237 + * }
152.238 + *
152.239 + * protected Set<String> handleKeySet() {
152.240 + * return new HashSet<String>(Arrays.asList("cancelKey"));
152.241 + * }
152.242 + * }
152.243 + * </pre>
152.244 + * </blockquote>
152.245 + * You do not have to restrict yourself to using a single family of
152.246 + * <code>ResourceBundle</code>s. For example, you could have a set of bundles for
152.247 + * exception messages, <code>ExceptionResources</code>
152.248 + * (<code>ExceptionResources_fr</code>, <code>ExceptionResources_de</code>, ...),
152.249 + * and one for widgets, <code>WidgetResource</code> (<code>WidgetResources_fr</code>,
152.250 + * <code>WidgetResources_de</code>, ...); breaking up the resources however you like.

152.740 + * then the base name is the only candidate bundle name. Otherwise, a list
152.741 + * of candidate locales is generated from the attribute values of the
152.742 + * specified locale (language, script, country and variant) and appended to
152.743 + * the base name. Typically, this will look like the following:
152.744 + *
152.745 + * <pre>
152.746 + * baseName + "_" + language + "_" + script + "_" + country + "_" + variant
152.747 + * baseName + "_" + language + "_" + script + "_" + country

152.751 + * baseName + "_" + language
152.752 + * </pre>
152.753 + *
152.754 + * <p>Candidate bundle names where the final component is an empty string
152.755 + * are omitted, along with the underscore. For example, if country is an
152.756 + * empty string, the second and the fifth candidate bundle names above
152.757 + * would be omitted. Also, if script is an empty string, the candidate names
152.758 + * including script are omitted. For example, a locale with language "de"
152.759 + * and variant "JAVA" will produce candidate names with base name
152.760 + * "MyResource" below.
152.761 + *
152.762 + * <pre>
152.763 + * MyResource_de__JAVA
152.764 + * MyResource_de
152.765 + * </pre>
152.766 + *
152.767 + * In the case that the variant contains one or more underscores ('_'), a
152.768 + * sequence of bundle names generated by truncating the last underscore and
152.769 + * the part following it is inserted after a candidate bundle name with the
152.770 + * original variant. For example, for a locale with language "en", script
152.771 + * "Latn, country "US" and variant "WINDOWS_VISTA", and bundle base name
152.772 + * "MyResource", the list of candidate bundle names below is generated:
152.773 + *
152.774 + * <pre>
152.775 + * MyResource_en_Latn_US_WINDOWS_VISTA
152.776 + * MyResource_en_Latn_US_WINDOWS
152.777 + * MyResource_en_Latn_US
152.778 + * MyResource_en_Latn
152.779 + * MyResource_en_US_WINDOWS_VISTA

152.790 + *
152.791 + * <p><code>getBundle</code> then iterates over the candidate bundle names
152.792 + * to find the first one for which it can <em>instantiate</em> an actual
152.793 + * resource bundle. It uses the default controls' {@link Control#getFormats
152.794 + * getFormats} method, which generates two bundle names for each generated
152.795 + * name, the first a class name and the second a properties file name. For
152.796 + * each candidate bundle name, it attempts to create a resource bundle:
152.797 + *
152.798 + * <ul><li>First, it attempts to load a class using the generated class name.
152.799 + * If such a class can be found and loaded using the specified class
152.800 + * loader, is assignment compatible with ResourceBundle, is accessible from
152.801 + * ResourceBundle, and can be instantiated, <code>getBundle</code> creates a
152.802 + * new instance of this class and uses it as the <em>result resource
152.803 + * bundle</em>.
152.804 + *
152.805 + * <li>Otherwise, <code>getBundle</code> attempts to locate a property
152.806 + * resource file using the generated properties file name. It generates a
152.807 + * path name from the candidate bundle name by replacing all "." characters
152.808 + * with "/" and appending the string ".properties". It attempts to find a
152.809 + * "resource" with this name using {@link
152.810 + * java.lang.ClassLoader#getResource(java.lang.String)
152.811 + * ClassLoader.getResource}. (Note that a "resource" in the sense of
152.812 + * <code>getResource</code> has nothing to do with the contents of a
152.813 + * resource bundle, it is just a container of data, such as a file.) If it
152.814 + * finds a "resource", it attempts to create a new {@link
152.815 + * PropertyResourceBundle} instance from its contents. If successful, this
152.816 + * instance becomes the <em>result resource bundle</em>. </ul>
152.817 + *
152.818 + * <p>This continues until a result resource bundle is instantiated or the
152.819 + * list of candidate bundle names is exhausted. If no matching resource
152.820 + * bundle is found, the default control's {@link Control#getFallbackLocale
152.821 + * getFallbackLocale} method is called, which returns the current default
152.822 + * locale. A new sequence of candidate locale names is generated using this
152.823 + * locale and and searched again, as above.
152.824 + *
152.825 + * <p>If still no result bundle is found, the base name alone is looked up. If
152.826 + * this still fails, a <code>MissingResourceException</code> is thrown.
152.827 + *
152.828 + * <p><a name="parent_chain"/> Once a result resource bundle has been found,
152.829 + * its <em>parent chain</em> is instantiated. If the result bundle already
152.830 + * has a parent (perhaps because it was returned from a cache) the chain is
152.831 + * complete.
152.832 + *
152.833 + * <p>Otherwise, <code>getBundle</code> examines the remainder of the
152.834 + * candidate locale list that was used during the pass that generated the
152.835 + * result resource bundle. (As before, candidate bundle names where the
152.836 + * final component is an empty string are omitted.) When it comes to the
152.837 + * end of the candidate list, it tries the plain bundle name. With each of the
152.838 + * candidate bundle names it attempts to instantiate a resource bundle (first
152.839 + * looking for a class and then a properties file, as described above).
152.840 + *
152.841 + * <p>Whenever it succeeds, it calls the previously instantiated resource
152.842 + * bundle's {@link #setParent(java.util.ResourceBundle) setParent} method
152.843 + * with the new resource bundle. This continues until the list of names
152.844 + * is exhausted or the current bundle already has a non-null parent.
152.845 + *
152.846 + * <p>Once the parent chain is complete, the bundle is returned.
152.847 + *
152.848 + * <p><b>Note:</b> <code>getBundle</code> caches instantiated resource
152.849 + * bundles and might return the same resource bundle instance multiple times.
152.850 + *
152.851 + * <p><b>Note:</b>The <code>baseName</code> argument should be a fully
152.852 + * qualified class name. However, for compatibility with earlier versions,
152.853 + * Sun's Java SE Runtime Environments do not verify this, and so it is
152.854 + * possible to access <code>PropertyResourceBundle</code>s by specifying a
152.855 + * path name (using "/") instead of a fully qualified class name (using
152.856 + * ".").

152.932 + * to produce bundle or resource names. The strings
152.933 + * <code>"java.class"</code> and <code>"java.properties"</code>

152.937 + * and must not be used for application-defined formats. Other strings

152.1014 + * finding a resource bundle. If the method returns a non-null locale,
152.1015 + * it becomes the next target locale and the loading process starts over

152.1018 + * MissingResourceException is thrown.</li>
152.1019 + *
152.1020 + * <li>At this point, we have found a resource bundle that's not the
152.1021 + * base bundle. If this bundle set its parent during its instantiation,
152.1022 + * it is returned to the caller. Otherwise, its <a

152.1028 + * <p>During the resource bundle loading process above, this factory

152.1030 + * Control#newBundle(String, Locale, String, ClassLoader, boolean)
152.1031 + * control.newBundle} method. If the time-to-live period of the

152.1035 + * method to determine whether the resource bundle needs to be reloaded.
152.1036 + * If reloading is required, the factory method calls
152.1037 + * <code>control.newBundle</code> to reload the resource bundle. If
152.1038 + * <code>control.newBundle</code> returns <code>null</code>, the factory
152.1039 + * method puts a dummy resource bundle in the cache as a mark of
152.1040 + * nonexistent resource bundles in order to avoid lookup overhead for

152.1042 + * expiration control as specified by <code>control</code>.
152.1043 + *

152.1059 + * </ul>
152.1060 + *
152.1061 + * <p>First, <code>getBundle</code> tries loading a resource bundle in

152.1684 + * methods during the bundle loading process. In other words, a
152.1685 + * <code>ResourceBundle.Control</code> collaborates with the factory
152.1686 + * methods for loading resource bundles. The default implementation of
152.1687 + * the callback methods provides the information necessary for the
152.1688 + * factory methods to perform the <a
152.1689 + * href="./ResourceBundle.html#default_behavior">default behavior</a>.
152.1690 + *
152.1691 + * <p>In addition to the callback methods, the {@link
152.1692 + * #toBundleName(String, Locale) toBundleName} and {@link
152.1693 + * #toResourceName(String, String) toResourceName} methods are defined
152.1694 + * primarily for convenience in implementing the callback
152.1695 + * methods. However, the <code>toBundleName</code> method could be
152.1696 + * overridden to provide different conventions in the organization and
152.1697 + * packaging of localized resources. The <code>toResourceName</code>
152.1698 + * method is <code>final</code> to avoid use of wrong resource and class
152.1699 + * name separators.
152.1700 + *
152.1701 + * <p>Two factory methods, {@link #getControl(List)} and {@link
152.1702 + * #getNoFallbackControl(List)}, provide
152.1703 + * <code>ResourceBundle.Control</code> instances that implement common
152.1704 + * variations of the default bundle loading process.
152.1705 + *
152.1706 + * <p>The formats returned by the {@link Control#getFormats(String)
152.1707 + * getFormats} method and candidate locales returned by the {@link
152.1708 + * ResourceBundle.Control#getCandidateLocales(String, Locale)
152.1709 + * getCandidateLocales} method must be consistent in all
152.1710 + * <code>ResourceBundle.getBundle</code> invocations for the same base
152.1711 + * bundle. Otherwise, the <code>ResourceBundle.getBundle</code> methods
152.1712 + * may return unintended bundles. For example, if only
152.1713 + * <code>"java.class"</code> is returned by the <code>getFormats</code>
152.1714 + * method for the first call to <code>ResourceBundle.getBundle</code>
152.1715 + * and only <code>"java.properties"</code> for the second call, then the
152.1716 + * second call will return the class-based one that has been cached
152.1717 + * during the first call.
152.1718 + *
152.1719 + * <p>A <code>ResourceBundle.Control</code> instance must be thread-safe
152.1720 + * if it's simultaneously used by multiple threads.
152.1721 + * <code>ResourceBundle.getBundle</code> does not synchronize to call
152.1722 + * the <code>ResourceBundle.Control</code> methods. The default
152.1723 + * implementations of the methods are thread-safe.
152.1724 + *
152.1725 + * <p>Applications can specify <code>ResourceBundle.Control</code>
152.1726 + * instances returned by the <code>getControl</code> factory methods or
152.1727 + * created from a subclass of <code>ResourceBundle.Control</code> to
152.1728 + * customize the bundle loading process. The following are examples of
152.1729 + * changing the default bundle loading process.
152.1730 + *
152.1731 + * <p><b>Example 1</b>
152.1732 + *
152.1733 + * <p>The following code lets <code>ResourceBundle.getBundle</code> look

152.1743 + * </pre>
152.1744 + *
152.1745 + * Given the resource bundles in the <a
152.1746 + * href="./ResourceBundle.html#default_behavior_example">example</a> in
152.1747 + * the <code>ResourceBundle.getBundle</code> description, this
152.1748 + * <code>ResourceBundle.getBundle</code> call loads
152.1749 + * <code>MyResources_fr_CH.properties</code> whose parent is
152.1750 + * <code>MyResources_fr.properties</code> whose parent is
152.1751 + * <code>MyResources.properties</code>. (<code>MyResources_fr_CH.properties</code>

152.2061 + * <code>Locale</code>s by omitting the variant subtags one by one, then
152.2062 + * insert them after every occurence of <code> Locale</code>s with the
152.2063 + * full variant value in the original list. For example, if the

152.2065 + *
152.2066 + * <ul>

152.2077 + *
152.2078 + * <li>Special cases for Chinese. When an input <code>Locale</code> has the
152.2079 + * language "zh" (Chinese) and an empty script value, either "Hans" (Simplified) or
152.2080 + * "Hant" (Traditional) might be supplied, depending on the country.
152.2081 + * When the country is "CN" (China) or "SG" (Singapore), "Hans" is supplied.
152.2082 + * When the country is "HK" (Hong Kong SAR China), "MO" (Macau SAR China),
152.2083 + * or "TW" (Taiwan), "Hant" is supplied. For all other countries or when the country
152.2084 + * is empty, no script is supplied. For example, for <code>Locale("zh", "CN")
152.2085 + * </code>, the candidate list will be:
152.2086 + * <ul>
152.2087 + * <li> [<em>L</em>("zh"), <em>S</em>("Hans"), <em>C</em>("CN")]
152.2088 + * <li> [<em>L</em>("zh"), <em>S</em>("Hans")]
152.2089 + * <li> [<em>L</em>("zh"), <em>C</em>("CN")]
152.2090 + * <li> [<em>L</em>("zh")]
152.2091 + * <li> <code>Locale.ROOT</code>
152.2092 + * </ul>
152.2093 + *
152.2094 + * For <code>Locale("zh", "TW")</code>, the candidate list will be:
152.2095 + * <ul>
152.2096 + * <li> [<em>L</em>("zh"), <em>S</em>("Hant"), <em>C</em>("TW")]
152.2097 + * <li> [<em>L</em>("zh"), <em>S</em>("Hant")]
152.2098 + * <li> [<em>L</em>("zh"), <em>C</em>("TW")]
152.2099 + * <li> [<em>L</em>("zh")]
152.2100 + * <li> <code>Locale.ROOT</code>
152.2101 + * </ul>
152.2102 + *
152.2103 + * <li>Special cases for Norwegian. Both <code>Locale("no", "NO",
152.2104 + * "NY")</code> and <code>Locale("nn", "NO")</code> represent Norwegian
152.2105 + * Nynorsk. When a locale's language is "nn", the standard candidate
152.2106 + * list is generated up to [<em>L</em>("nn")], and then the following
152.2107 + * candidates are added:
152.2108 + *
152.2109 + * <ul><li> [<em>L</em>("no"), <em>C</em>("NO"), <em>V</em>("NY")]
152.2110 + * <li> [<em>L</em>("no"), <em>C</em>("NO")]
152.2111 + * <li> [<em>L</em>("no")]
152.2112 + * <li> <code>Locale.ROOT</code>
152.2113 + * </ul>
152.2114 + *
152.2115 + * If the locale is exactly <code>Locale("no", "NO", "NY")</code>, it is first
152.2116 + * converted to <code>Locale("nn", "NO")</code> and then the above procedure is
152.2117 + * followed.
152.2118 + *
152.2119 + * <p>Also, Java treats the language "no" as a synonym of Norwegian
152.2120 + * Bokmål "nb". Except for the single case <code>Locale("no",
152.2121 + * "NO", "NY")</code> (handled above), when an input <code>Locale</code>
152.2122 + * has language "no" or "nb", candidate <code>Locale</code>s with
152.2123 + * language code "no" and "nb" are interleaved, first using the
152.2124 + * requested language, then using its synonym. For example,
152.2125 + * <code>Locale("nb", "NO", "POSIX")</code> generates the following
152.2126 + * candidate list:
152.2127 + *
152.2128 + * <ul>
152.2129 + * <li> [<em>L</em>("nb"), <em>C</em>("NO"), <em>V</em>("POSIX")]
152.2130 + * <li> [<em>L</em>("no"), <em>C</em>("NO"), <em>V</em>("POSIX")]
152.2131 + * <li> [<em>L</em>("nb"), <em>C</em>("NO")]
152.2132 + * <li> [<em>L</em>("no"), <em>C</em>("NO")]
152.2133 + * <li> [<em>L</em>("nb")]
152.2134 + * <li> [<em>L</em>("no")]
152.2135 + * <li> <code>Locale.ROOT</code>
152.2136 + * </ul>
152.2137 + *
152.2138 + * <code>Locale("no", "NO", "POSIX")</code> would generate the same list
152.2139 + * except that locales with "no" would appear before the corresponding
152.2140 + * locales with "nb".</li>
152.2141 + *
152.2142 + * </li>
152.2143 + * </ol>
152.2144 + *
152.2145 + * <p>The default implementation uses an {@link ArrayList} that
152.2146 + * overriding implementations may modify before returning it to the
152.2147 + * caller. However, a subclass must not modify it after it has
152.2148 + * been returned by <code>getCandidateLocales</code>.
152.2149 + *
152.2150 + * <p>For example, if the given <code>baseName</code> is "Messages"
152.2151 + * and the given <code>locale</code> is
152.2152 + * <code>Locale("ja", "", "XX")</code>, then a
152.2153 + * <code>List</code> of <code>Locale</code>s:

152.2158 + * </pre>
152.2159 + * is returned. And if the resource bundles for the "ja" and

152.2380 + * ignored for loading class-based resource bundles in this default
152.2381 + * implementation.</li>

153.49 +/**
153.50 + * <code>SimpleTimeZone</code> is a concrete subclass of <code>TimeZone</code>
153.51 + * that represents a time zone for use with a Gregorian calendar.
153.52 + * The class holds an offset from GMT, called <em>raw offset</em>, and start
153.53 + * and end rules for a daylight saving time schedule. Since it only holds
153.54 + * single values for each, it cannot handle historical changes in the offset
153.55 + * from GMT and the daylight saving schedule, except that the {@link
153.56 + * #setStartYear setStartYear} method can specify the year when the daylight
153.57 + * saving time schedule starts in effect.
153.58 + * <p>
153.59 + * To construct a <code>SimpleTimeZone</code> with a daylight saving time
153.60 + * schedule, the schedule can be described with a set of rules,
153.61 + * <em>start-rule</em> and <em>end-rule</em>. A day when daylight saving time
153.62 + * starts or ends is specified by a combination of <em>month</em>,
153.63 + * <em>day-of-month</em>, and <em>day-of-week</em> values. The <em>month</em>
153.64 + * value is represented by a Calendar {@link Calendar#MONTH MONTH} field
153.65 + * value, such as {@link Calendar#MARCH}. The <em>day-of-week</em> value is
153.66 + * represented by a Calendar {@link Calendar#DAY_OF_WEEK DAY_OF_WEEK} value,
153.67 + * such as {@link Calendar#SUNDAY SUNDAY}. The meanings of value combinations
153.68 + * are as follows.
153.69 + *
153.70 + * <ul>
153.71 + * <li><b>Exact day of month</b><br>
153.72 + * To specify an exact day of month, set the <em>month</em> and
153.73 + * <em>day-of-month</em> to an exact value, and <em>day-of-week</em> to zero. For
153.74 + * example, to specify March 1, set the <em>month</em> to {@link Calendar#MARCH
153.75 + * MARCH}, <em>day-of-month</em> to 1, and <em>day-of-week</em> to 0.</li>
153.76 + *
153.77 + * <li><b>Day of week on or after day of month</b><br>
153.78 + * To specify a day of week on or after an exact day of month, set the
153.79 + * <em>month</em> to an exact month value, <em>day-of-month</em> to the day on
153.80 + * or after which the rule is applied, and <em>day-of-week</em> to a negative {@link
153.81 + * Calendar#DAY_OF_WEEK DAY_OF_WEEK} field value. For example, to specify the
153.82 + * second Sunday of April, set <em>month</em> to {@link Calendar#APRIL APRIL},
153.83 + * <em>day-of-month</em> to 8, and <em>day-of-week</em> to <code>-</code>{@link
153.84 + * Calendar#SUNDAY SUNDAY}.</li>
153.85 + *
153.86 + * <li><b>Day of week on or before day of month</b><br>
153.87 + * To specify a day of the week on or before an exact day of the month, set
153.88 + * <em>day-of-month</em> and <em>day-of-week</em> to a negative value. For
153.89 + * example, to specify the last Wednesday on or before the 21st of March, set
153.90 + * <em>month</em> to {@link Calendar#MARCH MARCH}, <em>day-of-month</em> is -21
153.91 + * and <em>day-of-week</em> is <code>-</code>{@link Calendar#WEDNESDAY WEDNESDAY}. </li>
153.92 + *
153.93 + * <li><b>Last day-of-week of month</b><br>
153.94 + * To specify, the last day-of-week of the month, set <em>day-of-week</em> to a
153.95 + * {@link Calendar#DAY_OF_WEEK DAY_OF_WEEK} value and <em>day-of-month</em> to
153.96 + * -1. For example, to specify the last Sunday of October, set <em>month</em>
153.97 + * to {@link Calendar#OCTOBER OCTOBER}, <em>day-of-week</em> to {@link
153.98 + * Calendar#SUNDAY SUNDAY} and <em>day-of-month</em> to -1. </li>
153.99 + *
153.100 + * </ul>
153.101 + * The time of the day at which daylight saving time starts or ends is
153.102 + * specified by a millisecond value within the day. There are three kinds of
153.103 + * <em>mode</em>s to specify the time: {@link #WALL_TIME}, {@link
153.104 + * #STANDARD_TIME} and {@link #UTC_TIME}. For example, if daylight
153.105 + * saving time ends
153.106 + * at 2:00 am in the wall clock time, it can be specified by 7200000
153.107 + * milliseconds in the {@link #WALL_TIME} mode. In this case, the wall clock time
153.108 + * for an <em>end-rule</em> means the same thing as the daylight time.
153.109 + * <p>
153.110 + * The following are examples of parameters for constructing time zone objects.
153.111 + * <pre><code>

153.1301 + // INTERNAL REPRESENTATION
153.1302 + // This is the format SimpleTimeZone objects take after construction or
153.1303 + // streaming in is complete. Rules are represented directly, using an
153.1304 + // unencoded format. We will discuss the start rule only below; the end
153.1305 + // rule is analogous.
153.1306 + // startMode Takes on enumerated values DAY_OF_MONTH,
153.1307 + // DOW_IN_MONTH, DOW_AFTER_DOM, or DOW_BEFORE_DOM.
153.1308 + // startDay The day of the month, or for DOW_IN_MONTH mode, a

153.1310 + // +2 for second, -1 for last, etc.
153.1311 + // startDayOfWeek The day of the week. Ignored for DAY_OF_MONTH.
153.1312 + //
153.1313 + // ENCODED REPRESENTATION
153.1314 + // This is the format accepted by the constructor and by setStartRule()
153.1315 + // and setEndRule(). It uses various combinations of positive, negative,
153.1316 + // and zero values to encode the different rules. This representation
153.1317 + // allows us to specify all the different rule flavors without altering
153.1318 + // the API.
153.1319 + // MODE startMonth startDay startDayOfWeek

154.50 +/**
154.51 + * <code>TimeZone</code> represents a time zone offset, and also figures out daylight
154.52 + * savings.
154.53 + *
154.54 + * <p>
154.55 + * Typically, you get a <code>TimeZone</code> using <code>getDefault</code>
154.56 + * which creates a <code>TimeZone</code> based on the time zone where the program
154.57 + * is running. For example, for a program running in Japan, <code>getDefault</code>
154.58 + * creates a <code>TimeZone</code> object based on Japanese Standard Time.
154.59 + *
154.60 + * <p>
154.61 + * You can also get a <code>TimeZone</code> using <code>getTimeZone</code>
154.62 + * along with a time zone ID. For instance, the time zone ID for the
154.63 + * U.S. Pacific Time zone is "America/Los_Angeles". So, you can get a
154.64 + * U.S. Pacific Time <code>TimeZone</code> object with:
154.65 + * <blockquote><pre>
154.66 + * TimeZone tz = TimeZone.getTimeZone("America/Los_Angeles");
154.67 + * </pre></blockquote>
154.68 + * You can use the <code>getAvailableIDs</code> method to iterate through
154.69 + * all the supported time zone IDs. You can then choose a
154.70 + * supported ID to get a <code>TimeZone</code>.
154.71 + * If the time zone you want is not represented by one of the
154.72 + * supported IDs, then a custom time zone ID can be specified to
154.73 + * produce a TimeZone. The syntax of a custom time zone ID is:
154.74 + *
154.75 + * <blockquote><pre>
154.76 + * <a name="CustomID"><i>CustomID:</i></a>
154.77 + * <code>GMT</code> <i>Sign</i> <i>Hours</i> <code>:</code> <i>Minutes</i>
154.78 + * <code>GMT</code> <i>Sign</i> <i>Hours</i> <i>Minutes</i>
154.79 + * <code>GMT</code> <i>Sign</i> <i>Hours</i>
154.80 + * <i>Sign:</i> one of
154.81 + * <code>+ -</code>
154.82 + * <i>Hours:</i>
154.83 + * <i>Digit</i>
154.84 + * <i>Digit</i> <i>Digit</i>
154.85 + * <i>Minutes:</i>
154.86 + * <i>Digit</i> <i>Digit</i>
154.87 + * <i>Digit:</i> one of
154.88 + * <code>0 1 2 3 4 5 6 7 8 9</code>
154.89 + * </pre></blockquote>
154.90 + *
154.91 + * <i>Hours</i> must be between 0 to 23 and <i>Minutes</i> must be
154.92 + * between 00 to 59. For example, "GMT+10" and "GMT+0010" mean ten
154.93 + * hours and ten minutes ahead of GMT, respectively.
154.94 + * <p>
154.95 + * The format is locale independent and digits must be taken from the
154.96 + * Basic Latin block of the Unicode standard. No daylight saving time
154.97 + * transition schedule can be specified with a custom time zone ID. If
154.98 + * the specified string doesn't match the syntax, <code>"GMT"</code>
154.99 + * is used.
154.100 + * <p>
154.101 + * When creating a <code>TimeZone</code>, the specified custom time
154.102 + * zone ID is normalized in the following syntax:
154.103 + * <blockquote><pre>
154.104 + * <a name="NormalizedCustomID"><i>NormalizedCustomID:</i></a>
154.105 + * <code>GMT</code> <i>Sign</i> <i>TwoDigitHours</i> <code>:</code> <i>Minutes</i>
154.106 + * <i>Sign:</i> one of
154.107 + * <code>+ -</code>
154.108 + * <i>TwoDigitHours:</i>
154.109 + * <i>Digit</i> <i>Digit</i>
154.110 + * <i>Minutes:</i>
154.111 + * <i>Digit</i> <i>Digit</i>
154.112 + * <i>Digit:</i> one of
154.113 + * <code>0 1 2 3 4 5 6 7 8 9</code>
154.114 + * </pre></blockquote>
154.115 + * For example, TimeZone.getTimeZone("GMT-8").getID() returns "GMT-08:00".
154.116 + *
154.117 + * <h4>Three-letter time zone IDs</h4>
154.118 + *
154.119 + * For compatibility with JDK 1.1.x, some other three-letter time zone IDs
154.120 + * (such as "PST", "CTT", "AST") are also supported. However, <strong>their
154.121 + * use is deprecated</strong> because the same abbreviation is often used
154.122 + * for multiple time zones (for example, "CST" could be U.S. "Central Standard
154.123 + * Time" and "China Standard Time"), and the Java platform can then only

155.34 +/**
155.35 + * A facility for threads to schedule tasks for future execution in a
155.36 + * background thread. Tasks may be scheduled for one-time execution, or for
155.37 + * repeated execution at regular intervals.
155.38 + *
155.39 + * <p>Corresponding to each <tt>Timer</tt> object is a single background
155.40 + * thread that is used to execute all of the timer's tasks, sequentially.
155.41 + * Timer tasks should complete quickly. If a timer task takes excessive time
155.42 + * to complete, it "hogs" the timer's task execution thread. This can, in
155.43 + * turn, delay the execution of subsequent tasks, which may "bunch up" and
155.44 + * execute in rapid succession when (and if) the offending task finally
155.45 + * completes.
155.46 + *
155.47 + * <p>After the last live reference to a <tt>Timer</tt> object goes away
155.48 + * <i>and</i> all outstanding tasks have completed execution, the timer's task
155.49 + * execution thread terminates gracefully (and becomes subject to garbage
155.50 + * collection). However, this can take arbitrarily long to occur. By
155.51 + * default, the task execution thread does not run as a <i>daemon thread</i>,
155.52 + * so it is capable of keeping an application from terminating. If a caller
155.53 + * wants to terminate a timer's task execution thread rapidly, the caller
155.54 + * should invoke the timer's <tt>cancel</tt> method.
155.55 + *
155.56 + * <p>If the timer's task execution thread terminates unexpectedly, for
155.57 + * example, because its <tt>stop</tt> method is invoked, any further
155.58 + * attempt to schedule a task on the timer will result in an
155.59 + * <tt>IllegalStateException</tt>, as if the timer's <tt>cancel</tt>
155.60 + * method had been invoked.
155.61 + *
155.62 + * <p>This class is thread-safe: multiple threads can share a single
155.63 + * <tt>Timer</tt> object without the need for external synchronization.
155.64 + *
155.65 + * <p>This class does <i>not</i> offer real-time guarantees: it schedules
155.66 + * tasks using the <tt>Object.wait(long)</tt> method.
155.67 + *
155.68 + * <p>Java 5.0 introduced the {@code java.util.concurrent} package and
155.69 + * one of the concurrency utilities therein is the {@link
155.70 + * java.util.concurrent.ScheduledThreadPoolExecutor
155.71 + * ScheduledThreadPoolExecutor} which is a thread pool for repeatedly
155.72 + * executing tasks at a given rate or delay. It is effectively a more
155.73 + * versatile replacement for the {@code Timer}/{@code TimerTask}
155.74 + * combination, as it allows multiple service threads, accepts various
155.75 + * time units, and doesn't require subclassing {@code TimerTask} (just
155.76 + * implement {@code Runnable}). Configuring {@code
155.77 + * ScheduledThreadPoolExecutor} with one thread makes it equivalent to
155.78 + * {@code Timer}.
155.79 + *
155.80 + * <p>Implementation note: This class scales to large numbers of concurrently
155.81 + * scheduled tasks (thousands should present no problem). Internally,
155.82 + * it uses a binary heap to represent its task queue, so the cost to schedule
155.83 + * a task is O(log n), where n is the number of concurrently scheduled tasks.
155.84 + *
155.85 + * <p>Implementation note: All constructors start a timer thread.

157.46 +/**
157.47 + * A hash table supporting full concurrency of retrievals and adjustable
157.48 + * expected concurrency for updates. This class obeys the same functional
157.49 + * specification as {@link java.util.Hashtable}, and includes versions of
157.50 + * methods corresponding to each method of
157.51 + * <tt>Hashtable</tt>. However, even though all operations are thread-safe,
157.52 + * retrieval operations do <em>not</em> entail locking, and there is
157.53 + * <em>not</em> any support for locking the entire table in a way that prevents
157.54 + * all access. This class is fully interoperable with <tt>Hashtable</tt> in
157.55 + * programs that rely on its thread safety but not on its synchronization
157.56 + * details.
157.57 + *
157.58 + * <p>
157.59 + * Retrieval operations (including <tt>get</tt>) generally do not block, so may
157.60 + * overlap with update operations (including
157.61 + * <tt>put</tt> and <tt>remove</tt>). Retrievals reflect the results of the most
157.62 + * recently <em>completed</em> update operations holding upon their onset. For
157.63 + * aggregate operations such as <tt>putAll</tt>
157.64 + * and <tt>clear</tt>, concurrent retrievals may reflect insertion or removal of
157.65 + * only some entries. Similarly, Iterators and Enumerations return elements
157.66 + * reflecting the state of the hash table at some point at or since the creation
157.67 + * of the iterator/enumeration. They do <em>not</em> throw
157.68 + * {@link ConcurrentModificationException}. However, iterators are designed to
157.69 + * be used by only one thread at a time.
157.70 + *
157.71 + * <p>
157.72 + * The allowed concurrency among update operations is guided by the optional
157.73 + * <tt>concurrencyLevel</tt> constructor argument (default <tt>16</tt>), which
157.74 + * is used as a hint for internal sizing. The table is internally partitioned to
157.75 + * try to permit the indicated number of concurrent updates without contention.
157.76 + * Because placement in hash tables is essentially random, the actual
157.77 + * concurrency will vary. Ideally, you should choose a value to accommodate as
157.78 + * many threads as will ever concurrently modify the table. Using a
157.79 + * significantly higher value than you need can waste space and time, and a
157.80 + * significantly lower value can lead to thread contention. But overestimates
157.81 + * and underestimates within an order of magnitude do not usually have much
157.82 + * noticeable impact. A value of one is appropriate when it is known that only
157.83 + * one thread will modify and all others will only read. Also, resizing this or
157.84 + * any other kind of hash table is a relatively slow operation, so, when
157.85 + * possible, it is a good idea to provide estimates of expected table sizes in
157.86 + * constructors.
157.87 + *
157.88 + * <p>
157.89 + * This class and its views and iterators implement all of the
157.90 + * <em>optional</em> methods of the {@link Map} and {@link Iterator} interfaces.
157.91 + *
157.92 + * <p>
157.93 + * Like {@link Hashtable} but unlike {@link HashMap}, this class does
157.94 + * <em>not</em> allow <tt>null</tt> to be used as a key or value.

166.39 +/**
166.40 + * A small toolkit of classes that support lock-free thread-safe
166.41 + * programming on single variables. In essence, the classes in this
166.42 + * package extend the notion of {@code volatile} values, fields, and
166.43 + * array elements to those that also provide an atomic conditional update
166.44 + * operation of the form:
166.45 + *
166.46 + * <pre>
166.47 + * boolean compareAndSet(expectedValue, updateValue);
166.48 + * </pre>
166.49 + *
166.50 + * <p>This method (which varies in argument types across different
166.51 + * classes) atomically sets a variable to the {@code updateValue} if it
166.52 + * currently holds the {@code expectedValue}, reporting {@code true} on
166.53 + * success. The classes in this package also contain methods to get and
166.54 + * unconditionally set values, as well as a weaker conditional atomic
166.55 + * update operation {@code weakCompareAndSet} described below.
166.56 + *
166.57 + * <p>The specifications of these methods enable implementations to
166.58 + * employ efficient machine-level atomic instructions that are available
166.59 + * on contemporary processors. However on some platforms, support may
166.60 + * entail some form of internal locking. Thus the methods are not
166.61 + * strictly guaranteed to be non-blocking --
166.62 + * a thread may block transiently before performing the operation.
166.63 + *
166.64 + * <p>Instances of classes
166.65 + * {@link java.util.concurrent.atomic.AtomicBoolean},
166.66 + * {@link java.util.concurrent.atomic.AtomicInteger},
166.67 + * {@link java.util.concurrent.atomic.AtomicLong}, and
166.68 + * {@link java.util.concurrent.atomic.AtomicReference}
166.69 + * each provide access and updates to a single variable of the
166.70 + * corresponding type. Each class also provides appropriate utility
166.71 + * methods for that type. For example, classes {@code AtomicLong} and
166.72 + * {@code AtomicInteger} provide atomic increment methods. One
166.73 + * application is to generate sequence numbers, as in:
166.74 + *
166.75 + * <pre>
166.76 + * class Sequencer {
166.77 + * private final AtomicLong sequenceNumber
166.78 + * = new AtomicLong(0);
166.79 + * public long next() {
166.80 + * return sequenceNumber.getAndIncrement();
166.81 + * }
166.82 + * }
166.83 + * </pre>
166.84 + *
166.85 + * <p>The memory effects for accesses and updates of atomics generally
166.86 + * follow the rules for volatiles, as stated in section 17.4 of
166.87 + * <cite>The Java™ Language Specification</cite>.
166.88 + *
166.89 + * <ul>
166.90 + *
166.91 + * <li> {@code get} has the memory effects of reading a
166.92 + * {@code volatile} variable.
166.93 + *
166.94 + * <li> {@code set} has the memory effects of writing (assigning) a
166.95 + * {@code volatile} variable.
166.96 + *
166.97 + * <li> {@code lazySet} has the memory effects of writing (assigning)
166.98 + * a {@code volatile} variable except that it permits reorderings with
166.99 + * subsequent (but not previous) memory actions that do not themselves
166.100 + * impose reordering constraints with ordinary non-{@code volatile}
166.101 + * writes. Among other usage contexts, {@code lazySet} may apply when
166.102 + * nulling out, for the sake of garbage collection, a reference that is
166.103 + * never accessed again.
166.104 + *
166.105 + * <li>{@code weakCompareAndSet} atomically reads and conditionally
166.106 + * writes a variable but does <em>not</em>
166.107 + * create any happens-before orderings, so provides no guarantees
166.108 + * with respect to previous or subsequent reads and writes of any
166.109 + * variables other than the target of the {@code weakCompareAndSet}.
166.110 + *
166.111 + * <li> {@code compareAndSet}
166.112 + * and all other read-and-update operations such as {@code getAndIncrement}
166.113 + * have the memory effects of both reading and
166.114 + * writing {@code volatile} variables.
166.115 + * </ul>
166.116 + *
166.117 + * <p>In addition to classes representing single values, this package
166.118 + * contains <em>Updater</em> classes that can be used to obtain
166.119 + * {@code compareAndSet} operations on any selected {@code volatile}
166.120 + * field of any selected class.
166.121 + *
166.122 + * {@link java.util.concurrent.atomic.AtomicReferenceFieldUpdater},
166.123 + * {@link java.util.concurrent.atomic.AtomicIntegerFieldUpdater}, and
166.124 + * {@link java.util.concurrent.atomic.AtomicLongFieldUpdater} are
166.125 + * reflection-based utilities that provide access to the associated
166.126 + * field types. These are mainly of use in atomic data structures in
166.127 + * which several {@code volatile} fields of the same node (for
166.128 + * example, the links of a tree node) are independently subject to
166.129 + * atomic updates. These classes enable greater flexibility in how
166.130 + * and when to use atomic updates, at the expense of more awkward
166.131 + * reflection-based setup, less convenient usage, and weaker
166.132 + * guarantees.
166.133 + *
166.134 + * <p>The
166.135 + * {@link java.util.concurrent.atomic.AtomicIntegerArray},
166.136 + * {@link java.util.concurrent.atomic.AtomicLongArray}, and
166.137 + * {@link java.util.concurrent.atomic.AtomicReferenceArray} classes
166.138 + * further extend atomic operation support to arrays of these types.
166.139 + * These classes are also notable in providing {@code volatile} access
166.140 + * semantics for their array elements, which is not supported for
166.141 + * ordinary arrays.
166.142 + *
166.143 + * <a name="Spurious">
166.144 + * <p>The atomic classes also support method {@code weakCompareAndSet},
166.145 + * which has limited applicability. On some platforms, the weak version
166.146 + * may be more efficient than {@code compareAndSet} in the normal case,
166.147 + * but differs in that any given invocation of the
166.148 + * {@code weakCompareAndSet} method may return {@code false}
166.149 + * <em>spuriously</em> (that is, for no apparent reason)</a>. A
166.150 + * {@code false} return means only that the operation may be retried if
166.151 + * desired, relying on the guarantee that repeated invocation when the
166.152 + * variable holds {@code expectedValue} and no other thread is also
166.153 + * attempting to set the variable will eventually succeed. (Such
166.154 + * spurious failures may for example be due to memory contention effects
166.155 + * that are unrelated to whether the expected and current values are
166.156 + * equal.) Additionally {@code weakCompareAndSet} does not provide
166.157 + * ordering guarantees that are usually needed for synchronization
166.158 + * control. However, the method may be useful for updating counters and
166.159 + * statistics when such updates are unrelated to the other
166.160 + * happens-before orderings of a program. When a thread sees an update
166.161 + * to an atomic variable caused by a {@code weakCompareAndSet}, it does
166.162 + * not necessarily see updates to any <em>other</em> variables that
166.163 + * occurred before the {@code weakCompareAndSet}. This may be
166.164 + * acceptable when, for example, updating performance statistics, but
166.165 + * rarely otherwise.
166.166 + *
166.167 + * <p>The {@link java.util.concurrent.atomic.AtomicMarkableReference}
166.168 + * class associates a single boolean with a reference. For example, this
166.169 + * bit might be used inside a data structure to mean that the object
166.170 + * being referenced has logically been deleted.
166.171 + *
166.172 + * The {@link java.util.concurrent.atomic.AtomicStampedReference}
166.173 + * class associates an integer value with a reference. This may be
166.174 + * used for example, to represent version numbers corresponding to
166.175 + * series of updates.
166.176 + *
166.177 + * <p>Atomic classes are designed primarily as building blocks for
166.178 + * implementing non-blocking data structures and related infrastructure
166.179 + * classes. The {@code compareAndSet} method is not a general
166.180 + * replacement for locking. It applies only when critical updates for an
166.181 + * object are confined to a <em>single</em> variable.
166.182 + *
166.183 + * <p>Atomic classes are not general purpose replacements for
166.184 + * {@code java.lang.Integer} and related classes. They do <em>not</em>
166.185 + * define methods such as {@code hashCode} and
166.186 + * {@code compareTo}. (Because atomic variables are expected to be
166.187 + * mutated, they are poor choices for hash table keys.) Additionally,
166.188 + * classes are provided only for those types that are commonly useful in
166.189 + * intended applications. For example, there is no atomic class for
166.190 + * representing {@code byte}. In those infrequent cases where you would
166.191 + * like to do so, you can use an {@code AtomicInteger} to hold
166.192 + * {@code byte} values, and cast appropriately.
166.193 + *
166.194 + * You can also hold floats using
166.195 + * {@link java.lang.Float#floatToIntBits} and
166.196 + * {@link java.lang.Float#intBitsToFloat} conversions, and doubles using
166.197 + * {@link java.lang.Double#doubleToLongBits} and
166.198 + * {@link java.lang.Double#longBitsToDouble} conversions.

170.32 +/**
170.33 + * An engine that performs match operations on a {@link java.lang.CharSequence
170.34 + * </code>character sequence<code>} by interpreting a {@link Pattern}.
170.35 + *
170.36 + * <p> A matcher is created from a pattern by invoking the pattern's {@link
170.37 + * Pattern#matcher matcher} method. Once created, a matcher can be used to
170.38 + * perform three different kinds of match operations:
170.39 + *
170.40 + * <ul>
170.41 + *
170.42 + * <li><p> The {@link #matches matches} method attempts to match the entire
170.43 + * input sequence against the pattern. </p></li>
170.44 + *
170.45 + * <li><p> The {@link #lookingAt lookingAt} method attempts to match the
170.46 + * input sequence, starting at the beginning, against the pattern. </p></li>
170.47 + *
170.48 + * <li><p> The {@link #find find} method scans the input sequence looking for
170.49 + * the next subsequence that matches the pattern. </p></li>
170.50 + *
170.51 + * </ul>
170.52 + *
170.53 + * <p> Each of these methods returns a boolean indicating success or failure.
170.54 + * More information about a successful match can be obtained by querying the
170.55 + * state of the matcher.
170.56 + *
170.57 + * <p> A matcher finds matches in a subset of its input called the
170.58 + * <i>region</i>. By default, the region contains all of the matcher's input.
170.59 + * The region can be modified via the{@link #region region} method and queried
170.60 + * via the {@link #regionStart regionStart} and {@link #regionEnd regionEnd}
170.61 + * methods. The way that the region boundaries interact with some pattern
170.62 + * constructs can be changed. See {@link #useAnchoringBounds
170.63 + * useAnchoringBounds} and {@link #useTransparentBounds useTransparentBounds}
170.64 + * for more details.
170.65 + *
170.66 + * <p> This class also defines methods for replacing matched subsequences with
170.67 + * new strings whose contents can, if desired, be computed from the match
170.68 + * result. The {@link #appendReplacement appendReplacement} and {@link
170.69 + * #appendTail appendTail} methods can be used in tandem in order to collect
170.70 + * the result into an existing string buffer, or the more convenient {@link
170.71 + * #replaceAll replaceAll} method can be used to create a string in which every
170.72 + * matching subsequence in the input sequence is replaced.
170.73 + *
170.74 + * <p> The explicit state of a matcher includes the start and end indices of
170.75 + * the most recent successful match. It also includes the start and end
170.76 + * indices of the input subsequence captured by each <a
170.77 + * href="Pattern.html#cg">capturing group</a> in the pattern as well as a total
170.78 + * count of such subsequences. As a convenience, methods are also provided for
170.79 + * returning these captured subsequences in string form.
170.80 + *
170.81 + * <p> The explicit state of a matcher is initially undefined; attempting to
170.82 + * query any part of it before a successful match will cause an {@link
170.83 + * IllegalStateException} to be thrown. The explicit state of a matcher is
170.84 + * recomputed by every match operation.
170.85 + *
170.86 + * <p> The implicit state of a matcher includes the input character sequence as
170.87 + * well as the <i>append position</i>, which is initially zero and is updated
170.88 + * by the {@link #appendReplacement appendReplacement} method.
170.89 + *
170.90 + * <p> A matcher may be reset explicitly by invoking its {@link #reset()}
170.91 + * method or, if a new input sequence is desired, its {@link
170.92 + * #reset(java.lang.CharSequence) reset(CharSequence)} method. Resetting a
170.93 + * matcher discards its explicit state information and sets the append position
170.94 + * to zero.
170.95 + *

170.97 + * threads. </p>

170.697 + * respectively. For <tt>$</tt><i>g</i><tt></tt>,

171.39 + * A compiled representation of a regular expression.
171.40 + *
171.41 + * <p> A regular expression, specified as a string, must first be compiled into
171.42 + * an instance of this class. The resulting pattern can then be used to create
171.43 + * a {@link Matcher} object that can match arbitrary {@link
171.44 + * java.lang.CharSequence </code>character sequences<code>} against the regular
171.45 + * expression. All of the state involved in performing a match resides in the
171.46 + * matcher, so many matchers can share the same pattern.
171.47 + *
171.48 + * <p> A typical invocation sequence is thus
171.49 + *
171.50 + * <blockquote><pre>
171.51 + * Pattern p = Pattern.{@link #compile compile}("a*b");
171.52 + * Matcher m = p.{@link #matcher matcher}("aaaaab");
171.53 + * boolean b = m.{@link Matcher#matches matches}();</pre></blockquote>
171.54 + *
171.55 + * <p> A {@link #matches matches} method is defined by this class as a
171.56 + * convenience for when a regular expression is used just once. This method
171.57 + * compiles an expression and matches an input sequence against it in a single
171.58 + * invocation. The statement
171.59 + *
171.60 + * <blockquote><pre>
171.61 + * boolean b = Pattern.matches("a*b", "aaaaab");</pre></blockquote>
171.62 + *
171.63 + * is equivalent to the three statements above, though for repeated matches it
171.64 + * is less efficient since it does not allow the compiled pattern to be reused.
171.65 + *
171.66 + * <p> Instances of this class are immutable and are safe for use by multiple
171.67 + * concurrent threads. Instances of the {@link Matcher} class are not safe for
171.68 + * such use.

171.359 + * <h4> Backslashes, escapes, and quoting </h4>
171.360 + *
171.361 + * <p> The backslash character (<tt>'\'</tt>) serves to introduce escaped
171.362 + * constructs, as defined in the table above, as well as to quote characters
171.363 + * that otherwise would be interpreted as unescaped constructs. Thus the
171.364 + * expression <tt>\\</tt> matches a single backslash and <tt>\{</tt> matches a
171.365 + * left brace.
171.366 + *
171.367 + * <p> It is an error to use a backslash prior to any alphabetic character that
171.368 + * does not denote an escaped construct; these are reserved for future
171.369 + * extensions to the regular-expression language. A backslash may be used
171.370 + * prior to a non-alphabetic character regardless of whether that character is
171.371 + * part of an unescaped construct.
171.372 + *
171.373 + * <p> Backslashes within string literals in Java source code are interpreted
171.374 + * as required by
171.375 + * <cite>The Java™ Language Specification</cite>
171.376 + * as either Unicode escapes (section 3.3) or other character escapes (section 3.10.6)
171.377 + * It is therefore necessary to double backslashes in string
171.378 + * literals that represent regular expressions to protect them from
171.379 + * interpretation by the Java bytecode compiler. The string literal
171.380 + * <tt>"\b"</tt>, for example, matches a single backspace character when
171.381 + * interpreted as a regular expression, while <tt>"\\b"</tt> matches a
171.382 + * word boundary. The string literal <tt>"\(hello\)"</tt> is illegal
171.383 + * and leads to a compile-time error; in order to match the string
171.384 + * <tt>(hello)</tt> the string literal <tt>"\\(hello\\)"</tt>
171.385 + * must be used.

171.389 + *
171.390 + * <p> Character classes may appear within other character classes, and
171.391 + * may be composed by the union operator (implicit) and the intersection
171.392 + * operator (<tt>&&</tt>).
171.393 + * The union operator denotes a class that contains every character that is
171.394 + * in at least one of its operand classes. The intersection operator

171.396 + * operand classes.
171.397 + *
171.398 + * <p> The precedence of character-class operators is as follows, from
171.399 + * highest to lowest:

171.435 + * <li> A newline (line feed) character (<tt>'\n'</tt>),

171.438 + * character (<tt>"\r\n"</tt>),
171.439 + *
171.440 + * <li> A standalone carriage-return character (<tt>'\r'</tt>),
171.441 + *
171.442 + * <li> A next-line character (<tt>'\u0085'</tt>),
171.443 + *

171.449 + * <p>If {@link #UNIX_LINES} mode is activated, then the only line terminators

171.453 + * terminator unless the {@link #DOTALL} flag is specified.

171.455 + * <p> By default, the regular expressions <tt>^</tt> and <tt>$</tt> ignore

171.529 + * Such escape sequences are also implemented directly by the regular-expression

171.714 + *
171.715 + * <p> Notable differences from Perl: </p>
171.716 + *
171.717 + * <ul>
171.718 + *
171.719 + * <li><p> In Perl, <tt>\1</tt> through <tt>\9</tt> are always interpreted
171.720 + * as back references; a backslash-escaped number greater than <tt>9</tt> is
171.721 + * treated as a back reference if at least that many subexpressions exist,
171.722 + * otherwise it is interpreted, if possible, as an octal escape. In this
171.723 + * class octal escapes must always begin with a zero. In this class,
171.724 + * <tt>\1</tt> through <tt>\9</tt> are always interpreted as back
171.725 + * references, and a larger number is accepted as a back reference if at
171.726 + * least that many subexpressions exist at that point in the regular
171.727 + * expression, otherwise the parser will drop digits until the number is
171.728 + * smaller or equal to the existing number of groups or it is one digit.
171.729 + * </p></li>
171.730 + *
171.731 + * <li><p> Perl uses the <tt>g</tt> flag to request a match that resumes
171.732 + * where the last match left off. This functionality is provided implicitly
171.733 + * by the {@link Matcher} class: Repeated invocations of the {@link
171.734 + * Matcher#find find} method will resume where the last match left off,
171.735 + * unless the matcher is reset. </p></li>
171.736 + *
171.737 + * <li><p> In Perl, embedded flags at the top level of an expression affect
171.738 + * the whole expression. In this class, embedded flags always take effect
171.739 + * at the point at which they appear, whether they are at the top level or
171.740 + * within a group; in the latter case, flags are restored at the end of the
171.741 + * group just as in Perl. </p></li>
171.742 + *
171.743 + * </ul>
171.744 + *

175.57 +/**
175.58 + * {@code Proxy} provides static methods for creating dynamic proxy
175.59 + * classes and instances, and it is also the superclass of all
175.60 + * dynamic proxy classes created by those methods.
175.61 + *
175.62 + * <p>To create a proxy for some interface {@code Foo}:
175.63 + * <pre>
175.64 + * InvocationHandler handler = new MyInvocationHandler(...);
175.65 + * Class proxyClass = Proxy.getProxyClass(
175.66 + * Foo.class.getClassLoader(), new Class[] { Foo.class });
175.67 + * Foo f = (Foo) proxyClass.
175.68 + * getConstructor(new Class[] { InvocationHandler.class }).
175.69 + * newInstance(new Object[] { handler });
175.70 + * </pre>
175.71 + * or more simply:
175.72 + * <pre>
175.73 + * Foo f = (Foo) Proxy.newProxyInstance(Foo.class.getClassLoader(),
175.74 + * new Class[] { Foo.class },
175.75 + * handler);
175.76 + * </pre>
175.77 + *
175.78 + * <p>A <i>dynamic proxy class</i> (simply referred to as a <i>proxy
175.79 + * class</i> below) is a class that implements a list of interfaces
175.80 + * specified at runtime when the class is created, with behavior as
175.81 + * described below.
175.82 + *
175.83 + * A <i>proxy interface</i> is such an interface that is implemented
175.84 + * by a proxy class.
175.85 + *
175.86 + * A <i>proxy instance</i> is an instance of a proxy class.
175.87 + *
175.88 + * Each proxy instance has an associated <i>invocation handler</i>
175.89 + * object, which implements the interface {@link InvocationHandler}.
175.90 + * A method invocation on a proxy instance through one of its proxy
175.91 + * interfaces will be dispatched to the {@link InvocationHandler#invoke
175.92 + * invoke} method of the instance's invocation handler, passing the proxy
175.93 + * instance, a {@code java.lang.reflect.Method} object identifying
175.94 + * the method that was invoked, and an array of type {@code Object}
175.95 + * containing the arguments. The invocation handler processes the
175.96 + * encoded method invocation as appropriate and the result that it
175.97 + * returns will be returned as the result of the method invocation on
175.98 + * the proxy instance.
175.99 + *
175.100 + * <p>A proxy class has the following properties:
175.101 + *
175.102 + * <ul>
175.103 + * <li>Proxy classes are public, final, and not abstract.
175.104 + *
175.105 + * <li>The unqualified name of a proxy class is unspecified. The space
175.106 + * of class names that begin with the string {@code "$Proxy"}
175.107 + * should be, however, reserved for proxy classes.
175.108 + *
175.109 + * <li>A proxy class extends {@code java.lang.reflect.Proxy}.
175.110 + *
175.111 + * <li>A proxy class implements exactly the interfaces specified at its
175.112 + * creation, in the same order.
175.113 + *
175.114 + * <li>If a proxy class implements a non-public interface, then it will
175.115 + * be defined in the same package as that interface. Otherwise, the
175.116 + * package of a proxy class is also unspecified. Note that package
175.117 + * sealing will not prevent a proxy class from being successfully defined
175.118 + * in a particular package at runtime, and neither will classes already
175.119 + * defined by the same class loader and the same package with particular
175.120 + * signers.
175.121 + *
175.122 + * <li>Since a proxy class implements all of the interfaces specified at
175.123 + * its creation, invoking {@code getInterfaces} on its
175.124 + * {@code Class} object will return an array containing the same
175.125 + * list of interfaces (in the order specified at its creation), invoking
175.126 + * {@code getMethods} on its {@code Class} object will return
175.127 + * an array of {@code Method} objects that include all of the
175.128 + * methods in those interfaces, and invoking {@code getMethod} will
175.129 + * find methods in the proxy interfaces as would be expected.
175.130 + *
175.131 + * <li>The {@link Proxy#isProxyClass Proxy.isProxyClass} method will
175.132 + * return true if it is passed a proxy class-- a class returned by
175.133 + * {@code Proxy.getProxyClass} or the class of an object returned by
175.134 + * {@code Proxy.newProxyInstance}-- and false otherwise.
175.135 + *
175.136 + * <li>The {@code java.security.ProtectionDomain} of a proxy class
175.137 + * is the same as that of system classes loaded by the bootstrap class
175.138 + * loader, such as {@code java.lang.Object}, because the code for a
175.139 + * proxy class is generated by trusted system code. This protection
175.140 + * domain will typically be granted
175.141 + * {@code java.security.AllPermission}.
175.142 + *
175.143 + * <li>Each proxy class has one public constructor that takes one argument,
175.144 + * an implementation of the interface {@link InvocationHandler}, to set
175.145 + * the invocation handler for a proxy instance. Rather than having to use
175.146 + * the reflection API to access the public constructor, a proxy instance
175.147 + * can be also be created by calling the {@link Proxy#newProxyInstance
175.148 + * Proxy.newProxyInstance} method, which combines the actions of calling
175.149 + * {@link Proxy#getProxyClass Proxy.getProxyClass} with invoking the
175.150 + * constructor with an invocation handler.
175.151 + * </ul>
175.152 + *
175.153 + * <p>A proxy instance has the following properties:
175.154 + *
175.155 + * <ul>
175.156 + * <li>Given a proxy instance {@code proxy} and one of the
175.157 + * interfaces implemented by its proxy class {@code Foo}, the
175.158 + * following expression will return true:
175.159 + * <pre>
175.160 + * {@code proxy instanceof Foo}
175.161 + * </pre>
175.162 + * and the following cast operation will succeed (rather than throwing
175.163 + * a {@code ClassCastException}):
175.164 + * <pre>
175.165 + * {@code (Foo) proxy}
175.166 + * </pre>
175.167 + *
175.168 + * <li>Each proxy instance has an associated invocation handler, the one
175.169 + * that was passed to its constructor. The static
175.170 + * {@link Proxy#getInvocationHandler Proxy.getInvocationHandler} method
175.171 + * will return the invocation handler associated with the proxy instance
175.172 + * passed as its argument.
175.173 + *
175.174 + * <li>An interface method invocation on a proxy instance will be
175.175 + * encoded and dispatched to the invocation handler's {@link
175.176 + * InvocationHandler#invoke invoke} method as described in the
175.177 + * documentation for that method.
175.178 + *
175.179 + * <li>An invocation of the {@code hashCode},
175.180 + * {@code equals}, or {@code toString} methods declared in
175.181 + * {@code java.lang.Object} on a proxy instance will be encoded and
175.182 + * dispatched to the invocation handler's {@code invoke} method in
175.183 + * the same manner as interface method invocations are encoded and
175.184 + * dispatched, as described above. The declaring class of the
175.185 + * {@code Method} object passed to {@code invoke} will be
175.186 + * {@code java.lang.Object}. Other public methods of a proxy
175.187 + * instance inherited from {@code java.lang.Object} are not
175.188 + * overridden by a proxy class, so invocations of those methods behave
175.189 + * like they do for instances of {@code java.lang.Object}.
175.190 + * </ul>
175.191 + *
175.192 + * <h3>Methods Duplicated in Multiple Proxy Interfaces</h3>
175.193 + *
175.194 + * <p>When two or more interfaces of a proxy class contain a method with
175.195 + * the same name and parameter signature, the order of the proxy class's
175.196 + * interfaces becomes significant. When such a <i>duplicate method</i>
175.197 + * is invoked on a proxy instance, the {@code Method} object passed
175.198 + * to the invocation handler will not necessarily be the one whose
175.199 + * declaring class is assignable from the reference type of the interface
175.200 + * that the proxy's method was invoked through. This limitation exists
175.201 + * because the corresponding method implementation in the generated proxy
175.202 + * class cannot determine which interface it was invoked through.
175.203 + * Therefore, when a duplicate method is invoked on a proxy instance,
175.204 + * the {@code Method} object for the method in the foremost interface
175.205 + * that contains the method (either directly or inherited through a
175.206 + * superinterface) in the proxy class's list of interfaces is passed to
175.207 + * the invocation handler's {@code invoke} method, regardless of the
175.208 + * reference type through which the method invocation occurred.
175.209 + *
175.210 + * <p>If a proxy interface contains a method with the same name and
175.211 + * parameter signature as the {@code hashCode}, {@code equals},
175.212 + * or {@code toString} methods of {@code java.lang.Object},
175.213 + * when such a method is invoked on a proxy instance, the
175.214 + * {@code Method} object passed to the invocation handler will have
175.215 + * {@code java.lang.Object} as its declaring class. In other words,
175.216 + * the public, non-final methods of {@code java.lang.Object}
175.217 + * logically precede all of the proxy interfaces for the determination of
175.218 + * which {@code Method} object to pass to the invocation handler.
175.219 + *
175.220 + * <p>Note also that when a duplicate method is dispatched to an
175.221 + * invocation handler, the {@code invoke} method may only throw
175.222 + * checked exception types that are assignable to one of the exception
175.223 + * types in the {@code throws} clause of the method in <i>all</i> of
175.224 + * the proxy interfaces that it can be invoked through. If the
175.225 + * {@code invoke} method throws a checked exception that is not
175.226 + * assignable to any of the exception types declared by the method in one
175.227 + * of the proxy interfaces that it can be invoked through, then an
175.228 + * unchecked {@code UndeclaredThrowableException} will be thrown by
175.229 + * the invocation on the proxy instance. This restriction means that not
175.230 + * all of the exception types returned by invoking
175.231 + * {@code getExceptionTypes} on the {@code Method} object
175.232 + * passed to the {@code invoke} method can necessarily be thrown
175.233 + * successfully by the {@code invoke} method.

175.297 + *
175.298 + * <p>There are several restrictions on the parameters that may be

175.300 + *
175.301 + * <ul>
175.302 + * <li>All of the {@code Class} objects in the

175.304 + * classes or primitive types.
175.305 + *
175.306 + * <li>No two elements in the {@code interfaces} array may
175.307 + * refer to identical {@code Class} objects.
175.308 + *
175.309 + * <li>All of the interface types must be visible by name through the
175.310 + * specified class loader. In other words, for class loader
175.311 + * {@code cl} and every interface {@code i}, the following
175.312 + * expression must be true:
175.313 + * <pre>
175.314 + * Class.forName(i.getName(), false, cl) == i
175.315 + * </pre>
175.316 + *
175.317 + * <li>All non-public interfaces must be in the same package;
175.318 + * otherwise, it would not be possible for the proxy class to
175.319 + * implement all of the interfaces, regardless of what package it is
175.320 + * defined in.
175.321 + *
175.322 + * <li>For any set of member methods of the specified interfaces
175.323 + * that have the same signature:
175.324 + * <ul>
175.325 + * <li>If the return type of any of the methods is a primitive
175.326 + * type or void, then all of the methods must have that same
175.327 + * return type.
175.328 + * <li>Otherwise, one of the methods must have a return type that
175.329 + * is assignable to all of the return types of the rest of the
175.330 + * methods.
175.331 + * </ul>
175.332 + *
175.333 + * <li>The resulting proxy class must not exceed any limits imposed
175.334 + * on classes by the virtual machine. For example, the VM may limit
175.335 + * the number of interfaces that a class may implement to 65535; in
175.336 + * that case, the size of the {@code interfaces} array must not
175.337 + * exceed 65535.
