import java.awt.*;

import javax.swing.*;

public class MouseTest
{
public static void main(String[] args)
{
MouseFrame frame=new MouseFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.show();
}

class MouseFrame extends JFrame
{
public MouseFrame()
{
setTitle("MouseTest");

MousePanel panel=new MousePanel();
Container contentPane=getContentPane();

public static final int DEFAULT_HEIGHT = 200;

}

class MousePanel extends JPanel {
