Moving Button timer

[kritikal]

Hey guys, been at this project for a week trying to get a Jbutton to move on a timer, and changing color when you click on it.

I have been unsuccessful, after doing some tedious research.

if anyone can give any hints, or assistance, will be much appreciated

thanks,
krit

Try this code:

import java.awt.Color;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.util.Random;
import java.util.Timer;
import java.util.TimerTask;
import javax.swing.JButton;
import javax.swing.JFrame;

public class MyFrame extends JFrame {

    private JButton myButton;

    public MyFrame() {
        /*
         * Initialize frame
         */
        super("Test");
        this.setSize(800, 600);
        this.setLayout(null);
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        /*
         * Initialize button
         */
        myButton = new JButton("Click");
        myButton.setLocation(10, 10);
        myButton.setSize(100, 20);

        /*
         * Schedule a job at a fixed rate
         */
        Timer t = new Timer();
        final Random r = new Random();
        t.scheduleAtFixedRate(new TimerTask() {

            // Change button location randomly
            public void run() {
                myButton.setLocation(r.nextInt(getWidth()), r.nextInt(getHeight()));
            }
        }, 0, 1000);

        myButton.addMouseListener(new MouseListener() {

            // On button click
            // Change background color
            public void mousePressed(MouseEvent e) {
                myButton.setBackground(new Color(r.nextInt(255), r.nextInt(255), r.nextInt(255)));
            }

            public void mouseClicked(MouseEvent e) {
            }

            public void mouseReleased(MouseEvent e) {
            }

            public void mouseEntered(MouseEvent e) {
            }

            public void mouseExited(MouseEvent e) {
            }
        });

        this.add(myButton);
    }

    public static void main(String[] args) {
        MyFrame frame = new MyFrame();
        frame.setVisible(true);
    }
}
