public class JSeparator
extends JComponent   
implements SwingConstants   , Accessible   

JSeparator provides a general purpose component for implementing divider lines - most commonly used as a divider between menu items that breaks them up into logical groupings. Instead of using JSeparator directly, you can use the JMenu or JPopupMenu addSeparator method to create and add a separator. JSeparators may also be used elsewhere in a GUI wherever a visual divider is useful.

For more information and examples see How to Use Menus, a section in The Java Tutorial.

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 .
