41 * The {@code Desktop} class allows a Java application to launch
42 * associated applications registered on the native desktop to handle
43 * a {@link java.net.URI} or a file.
44 *
45 * <p> Supported operations include:
46 * <ul>
47 * <li>launching the user-default browser to show a specified
48 * URI;</li>
49 * <li>launching the user-default mail client with an optional
50 * {@code mailto} URI;</li>
51 * <li>launching a registered application to open, edit or print a
52 * specified file.</li>
53 * </ul>
54 *
55 * <p> This class provides methods corresponding to these
56 * operations. The methods look for the associated application
57 * registered on the current platform, and launch it to handle a URI
58 * or file. If there is no associated application or the associated
59 * application fails to be launched, an exception is thrown.
60 *
61 * <p> An application is registered to a URI or file type; for
62 * example, the {@code "sxi"} file extension is typically registered
63 * to StarOffice. The mechanism of registering, accessing, and
64 * launching the associated application is platform-dependent.
65 *
66 * <p> Each operation is an action type represented by the {@link
67 * Desktop.Action} class.
68 *
69 * <p> Note: when some action is invoked and the associated
70 * application is executed, it will be executed on the same system as
71 * the one on which the Java application was launched.
