JSeparator dashed style

Question

I am using a JSeparator in my java swing application. The normal implementation makes the separator normal line; but what I need is the separator should be dashed(like we create dashed border). Is there any way we can do that?

Thanks

You can use the following code snippet to create a dashed line.

import java.awt.Container;
import java.awt.Graphics;
import java.awt.GridLayout;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JSeparator;

public class SeparatorSample {
    public static void main(String args[]) {
        JFrame f = new JFrame("JSeparator Sample");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Container content = f.getContentPane();
        content.setLayout(new GridLayout(0, 1));
        JLabel above = new JLabel("Above Separator");
        content.add(above);
        JSeparator separator = new JSeparator() {
            private static final long serialVersionUID = 1L;

            public void paintComponent(Graphics g) {
                for (int x = 0; x < 300; x += 15)
                    g.drawLine(x, 0, x + 10, 0);
            }
        };
        content.add(separator);
        JLabel below = new JLabel("Below Separator");
        content.add(below);
        f.setSize(300, 100);
        f.setVisible(true);
    }
}
