public class JRadioButton

extends JToggleButton

implements Accessible

An implementation of a radio button -- an item that can be selected or deselected, and which displays its state to the user. Used with a ButtonGroup object to create a group of buttons in which only one button at a time can be selected. (Create a ButtonGroup object and use its add method to include the JRadioButton objects in the group.)

Note:
The ButtonGroup object is a logical grouping -- not a physical grouping. Tocreate a button panel, you should still create a JPanel or similar container-object and add a Border to it to set it off from surrounding components.

See How to Use Radio Buttons in The Java Tutorial for further documentation.

For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the JRadioButton 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 Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.
