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

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);
  }

}
