JSeparator

1. The JSeparator class is a special component that acts as a separator on a JMenu.
2. JSeparator can be used anywhere you want to use a horizontal or vertical line to separate different areas of a screen.

The JSeparator class provides a horizontal or vertical dividing line or empty space

   <source lang="java">

import javax.swing.JFrame; import javax.swing.JSeparator; public class JSeparatorVERTICALHORI {

 public static void main(String[] a){
   JFrame frame = new JFrame();
   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

   frame.add(new JSeparator(JSeparator.VERTICAL));
   frame.setSize(300, 200);
   frame.setVisible(true);
 }
