java.lang.Object java.awt.Component java.awt.Container javax.swing.JComponent javax.swing.AbstractButton javax.swing.JMenuItem javax.swing.JRadioButtonMenuItem
An implementation of a radio button menu item. A JRadioButtonMenuItem 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 ButtonGroup object.
For further documentation and examples see
How to Use Menus
, a section in The Java Tutorial.
For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the

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 TM has been added to the java.beans package. Please see XMLEncoder .
