/**
* 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 <code>JMenuItem</code>
* contained in a <code>JPopupMenu</code> performs exactly that function.
* <p>
* Menu items can be configured, and to some degree controlled, by
* <code><a href="Action.html">Action</a></code>s. Using an
* <code>Action</code> with a menu item has many benefits beyond directly
* configuring a menu item. Refer to <a href="Action.html#buttonActions">
* Swing Components Supporting <code>Action</code></a> for more
* details, and you can find more information in <a
* href="https://docs.oracle.com/javase/tutorial/uiswing/misc/action.html">How
* to Use Actions</a>, a section in <em>The Java Tutorial</em>.
* <p>
* For further documentation and for examples, see
* <a
href="https://docs.oracle.com/javase/tutorial/uiswing/components/menu.html">How to Use Menus</a>
* in <em>The Java Tutorial.</em>

* <strong>Warning:</strong>
* Serialized objects of this class will not be compatible with

* the same version of Swing. As of 1.4, support for long term storage
