+/**
+ * An implementation of a radio button menu item.
+ * A <code>JRadioButtonMenuItem</code> is
+ * a menu item that is part of a group of menu items in which only one
+ * item in the group can be selected. The selected item displays its
+ * selected state. Selecting it causes any other selected item to
+ * switch to the unselected state.
+ * To control the selected state of a group of radio button menu items,
+ * use a <code>ButtonGroup</code> object.
+ * <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="http://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 examples see
+ * <a
+ href="http://docs.oracle.com/javase/tutorial/uiswing/components/menu.html">How to Use Menus</a>,
+ * a section in <em>The Java Tutorial.</em>
+ * <p>
+ * <strong>Warning:</strong> Swing is not thread safe. For more
+ * information see <a
+ * href="package-summary.html#threading">Swing's Threading
+ * Policy</a>.
+ * <p>
+ * <strong>Warning:</strong>
+ * 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 JavaBeans™
+ * has been added to the <code>java.beans</code> package.
+ * Please see {@link java.beans.XMLEncoder}.
