    Default Make a clickable moving image?

    I have an image moving across the screen and I would like to make it clickable. Everything I have tried does not work.

    I have tried adding an ActionListener, MouseListener, using an ImageIcon and JButton instead of Image.

    How can I make the moving image clickable?

    Java Code:
    import java.awt.*;
    import javax.swing.*;
    import java.awt.event.*;
    public class Main extends JFrame implements ActionListener{
        int xPos = -50;
        int yPos = 300;
        Image bob;
        Image bobImage;
        Graphics bobGraphics;
        public Main() {
            try {
              bob = Toolkit.getDefaultToolkit().getImage("spongeRun.png");
            catch(Exception e) {}
        public void update(Graphics g) {
        public void paint(Graphics g) {
            int width  = getWidth();
            int height = getHeight();
            if (bobImage == null) {
                bobImage    = createImage(width, height);
                bobGraphics = bobImage.getGraphics();
            bobGraphics.clearRect(0, 0, width + 1, height + 1);
            bobGraphics.drawImage(bob, xPos, yPos, this);
            g.drawImage(bobImage, 0, 0, this);
        void moveImage() {
            for ( int i = 0 ; i < 500 ; i++ ){
                xPos +=2;
                try { Thread.sleep(5); }
                catch (InterruptedException e) { System.err.println("poop!"); }
        public void actionPerformed(ActionEvent e){
        public static void main(String[] args) {
            Main me = new Main();

    I would do things very differently. For one, I try to avoid painting directly in the JFrame but rather in the paintComponent method of a JPanel or JComponent. In your situation since you want a clickable graphic, I'd do it differently still by creating an ImageIcon from the Image, placing it in a JLabel, adding a MouseListener to the JLabel, adding the JLabel to a container (JPanel) that uses null layout, taking care to set its bounds, and then moving the JLabel in a Swing timer. I'd avoid using a Thread.sleep(...) in a Swing application, and I'd not use the update method for Swing graphics (that's for AWT programs). YMMV.
