Java MouseMotionListener

I am writing a program that displays a number of random rectangles on screen as a screensaver. When I open the program it runs fine but I have set the screen to not display the JFrame. This leaves the obvious problem that ther's no way to stop the program running. I want to implement a mouse listener to close the screen when i move the mouse. However I've tried a few times but can't figure out where to call the methods. I have two classes, my screensaver class and a screensaver test class which contains the main method to run my program.

any help will be much appreciated as I am very new to java.

Code:

---

import java.awt.Color;
import java.awt.Graphics;
import java.util.Random;
import javax.swing.JPanel;
import javax.swing.Timer;
import java.awt.Graphics2D;
import java.awt.RenderingHints;
import java.awt.Font;
import java.text.DateFormat;
import java.util.Date;
import java.util.*;
import java.text.*;


public class Screensaver extends JPanel{

private Random rand = new Random();

public void paintComponent( Graphics g ){

super.paintComponent( g );
int x1, y1, x2, y2;

Date now = new Date();
DateFormat mediumDf = DateFormat.getDateInstance(DateFormat.MEDIUM);
String s = mediumDf.format(now);


for( int i = 0; i < 15; i++ )
{
x1 = rand.nextInt( 1366 );
x2 = rand.nextInt( 1366 );
y1 = rand.nextInt( 768 );
y2 = rand.nextInt( 768 );

g.setColor( new Color( rand.nextInt( 256 ),
rand.nextInt( 256 ), rand.nextInt( 256 ) ) );
g.drawRect( x1, y1, x2, y2 );



Graphics2D g3 = (Graphics2D)g;
Font font2 = new Font("Serif", Font.PLAIN, 64);
g2.setFont(font2);
g2.drawString("Date:" + s, 20, 700);

}

repaint(); // repaint component
try { Thread.sleep(500); } catch( InterruptedException e) {}
}

}

import java.awt.Color;
import java.awt.Dimension;
import java.awt.Toolkit;
import javax.swing.JFrame;
import java.awt.event.MouseListener;
import java.awt.event.MouseMotionListener;
import java.awt.event.MouseEvent;

public class ScreensaverTest implements MouseMotionListener
{
// execute application
public static void main( String[] args )
{
// create frame for ScreensaverJPanel
MouseMotionListener e = new MouseMotionListener();
JFrame frame =
new JFrame();
frame.setUndecorated( true );
frame.setVisible( true ); // display frame
frame.setExtendedState( JFrame.MAXIMIZED_BOTH );

Screensaver screensaver =
new Screensaver();
screensaver.setBackground( Color.BLACK );
frame.add( screensaver ); // add panel to frame
// set frame size
}

} // end main
// end class Screensaver

Sorry, the screensaver test class shouldn't implement mouselistener. i was uploading the working code.

import java.awt.Color;
import java.awt.Dimension;
import java.awt.Toolkit;
import javax.swing.JFrame;
import java.awt.event.MouseListener;
import java.awt.event.MouseMotionListener;
import java.awt.event.MouseEvent;

public class ScreensaverTest implements MouseMotionListener
{
// execute application
public static void main( String[] args )
{
// create frame for ScreensaverJPanel
MouseMotionListener e = new MouseMotionListener();
JFrame frame =
new JFrame();
frame.setUndecorated( true );
frame.setVisible( true ); // display frame
frame.setExtendedState( JFrame.MAXIMIZED_BOTH );

Screensaver screensaver =
new Screensaver();
screensaver.setBackground( Color.BLACK );
frame.add( screensaver ); // add panel to frame
// set frame size
}

} // end main
// end class Screensaver

once again sorry, forgot to edit it.

Code:

import java.awt.Color;
 import java.awt.Dimension;
 import java.awt.Toolkit;
 import javax.swing.JFrame;

 {
 // execute application

 new JFrame();
 frame.setUndecorated( true );
 frame.setVisible( true ); // display frame
 frame.setExtendedState( JFrame.MAXIMIZED_BOTH );
 
Screensaver screensaver =
 new Screensaver();
 screensaver.setBackground( Color.BLACK );
 frame.add( screensaver ); // add panel to frame
 // set frame size
 }
 
} // end main
 // end class Screensaver

I have set the screen to not display the JFrame

If the JFrame is not displayed, what is shown?
If there is nothing visible, can the program receive any GUI type events?

What are the three versions of ScreensaverTest for? Which one is to be used for testing?

How do you compile and execute the program?

Please make a single program the compiles, executes and show the problem. Your posted code does not compile.

Also be sure to use proper indentation. Do NOT have all the statements start in the first column. Indent the statements to reflect the logic/nesting levels.
