public class JCheckBox
extends JToggleButton   
implements Accessible   

An implementation of a check box -- an item that can be selected or deselected, and which displays its state to the user. By convention, any number of check boxes in a group can be selected. See How to Use Buttons, Check Boxes, and Radio Buttons in The Java Tutorial for examples and information on using check boxes.

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 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 .
