34 * Instances of the class {@code Class} represent classes and
35 * interfaces in a running Java application. An enum is a kind of
36 * class and an annotation is a kind of interface. Every array also
37 * belongs to a class that is reflected as a {@code Class} object
38 * that is shared by all arrays with the same element type and number
39 * of dimensions. The primitive Java types ({@code boolean},
40 * {@code byte}, {@code char}, {@code short},
41 * {@code int}, {@code long}, {@code float}, and
42 * {@code double}), and the keyword {@code void} are also
43 * represented as {@code Class} objects.
45 * <p> {@code Class} has no public constructor. Instead {@code Class}
46 * objects are constructed automatically by the Java Virtual Machine as classes
47 * are loaded and by calls to the {@code defineClass} method in the class
50 * <p> The following example uses a {@code Class} object to print the
51 * class name of an object:
53 * <p> <blockquote><pre>
54 * void printClassName(Object obj) {
55 * System.out.println("The class of " + obj +
56 * " is " + obj.getClass().getName());
60 * <p> It is also possible to get the {@code Class} object for a named
61 * type (or for void) using a class literal. See Section 15.8.2 of
62 * <cite>The Java™ Language Specification</cite>.
66 * {@code System.out.println("The name of class Foo is: "+Foo.class.getName());}
69 * @param <T> the type of the class modeled by this {@code Class}
70 * object. For example, the type of {@code String.class} is {@code
71 * Class<String>}. Use {@code Class<?>} if the class being modeled is
