/**
|
jaroslav@1258
|
33 |
* A <code>PrintStream</code> adds functionality to another output stream,
|
jaroslav@1258
|
34 |
* namely the ability to print representations of various data values
|
jaroslav@1258
|
35 |
* conveniently. Two other features are provided as well. Unlike other output
|
jaroslav@1258
|
36 |
* streams, a <code>PrintStream</code> never throws an
|
jaroslav@1258
|
37 |
* <code>IOException</code>; instead, exceptional situations merely set an
|
jaroslav@1258
|
38 |
* internal flag that can be tested via the <code>checkError</code> method.
|
jaroslav@1258
|
39 |
* Optionally, a <code>PrintStream</code> can be created so as to flush
|
jaroslav@1258
|
40 |
* automatically; this means that the <code>flush</code> method is
|
jaroslav@1258
|
41 |
* automatically invoked after a byte array is written, one of the
|
jaroslav@1258
|
42 |
* <code>println</code> methods is invoked, or a newline character or byte
|
jaroslav@1258
|
43 |
* (<code>'\n'</code>) is written.
|
jaroslav@1258
|
44 |
*
|
jaroslav@1258
|
45 |
* <p> All characters printed by a <code>PrintStream</code> are converted into
|
jaroslav@1258
|
46 |
* bytes using the platform's default character encoding. The <code>{@link
|
jaroslav@1258
|
47 |
* PrintWriter}</code> class should be used in situations that require writing
|
jaroslav@1258
|
48 |
* characters rather than bytes.
