public class JRadioButtonMenuItem
extends JMenuItem
implements Accessible

This class represents JRadioButtonMenuItem. Its behaviour is very similar to JRadioButton. Just like JRadioButton, user can check and uncheck this menu item by clicking on it. JRadioButtonMenuItem uses ToggleButtonModel to keep track of its selection. If the JRadioButtonMenuItem is included in the button group, then only one JRadioButtonMenuItem can be selected at one time.
