public class JMenuItem
extends AbstractButton
implements Accessible, MenuElement

An implementation of an item in a menu. A menu item is essentially a button sitting in a list. When the user selects the "button", the action associated with the menu item is performed. A JMenuItem contained in a JPopupMenu performs exactly that function.

For further documentation and for examples, see How to Use Menus in The Java Tutorial. For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the JMenuItem key assignments.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.
