public class JCheckBox
extends JToggleButton
implements Accessible
An implementation of a CheckBox -- an item that can be selected or deselected, and which displays its state to the user. In a group of checkboxes, multiple checkboxes can be selected. See How to Use CheckBoxes in The Java Tutorial for further documentation.

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.
