Help on moving of image across screen(java application,not applet)

Question

I've searched the entire internet and everything I've found is on java applets and I'm an alien to the differences between an applet and an application.
This is actually for a java game I'm creating using Eclipse's visual editor and I'm failing miserably.
What I'm trying to do is to find some java source code that enables me to start an image automatically moving across the screen that only stops when I click on it. I did find some applet codes but when I tried converting it to application code a load of errors popped out.
Thanks for the help if there's any! I'm getting desperate here because the game's due this friday and I'm stuck at this stage for who knows how long.

Answer 1

Here is one of the codes I found ,it's not mine but I'm trying to edit it into a java application instead of an applet...Sort of like: ' public class MovingLabels extends JFrame ' or some code that I can copy and paste into another java program.
* Swing version.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MovingLabels extends JApplet
implements ActionListener {
int frameNumber = -1;
Timer timer;
boolean frozen = false;
JLayeredPane layeredPane;
JLabel bgLabel, fgLabel;
int fgHeight, fgWidth;
int bgHeight, bgWidth;
static String fgFile = "wow.gif";
static String bgFile = "Spring.jpg";
//Invoked only when run as an applet.
public void init() {
Image bgImage = getImage(getCodeBase(), bgFile);
Image fgImage = getImage(getCodeBase(), fgFile);
buildUI(getContentPane(), bgImage, fgImage);
void buildUI(Container container, Image bgImage, Image fgImage) {
final ImageIcon bgIcon = new ImageIcon(bgImage);
final ImageIcon fgIcon = new ImageIcon(fgImage);
bgWidth = bgIcon.getIconWidth();
bgHeight = bgIcon.getIconHeight();
fgWidth = fgIcon.getIconWidth();
fgHeight = fgIcon.getIconHeight();
//Set up a timer that calls this object's action handler
timer = new Timer(100, this); //delay = 100 ms
timer.setInitialDelay(0);
timer.setCoalesce(true);
//Create a label to display the background image.
bgLabel = new JLabel(bgIcon);
bgLabel.setOpaque(true);
bgLabel.setBounds(0, 0, bgWidth, bgHeight);
//Create a label to display the foreground image.
fgLabel = new JLabel(fgIcon);
fgLabel.setBounds(-fgWidth, -fgHeight, fgWidth, fgHeight);
//Create the layered pane to hold the labels.
layeredPane = new JLayeredPane();
layeredPane.setPreferredSize(
new Dimension(bgWidth, bgHeight));
layeredPane.addMouseListener(new MouseAdapter() {
public void mousePressed(MouseEvent e) {
if (frozen) {
frozen = false;
startAnimation();
} else {
frozen = true;
stopAnimation();
layeredPane.add(bgLabel, new Integer(0)); //low layer
layeredPane.add(fgLabel, new Integer(1)); //high layer
container.add(layeredPane, BorderLayout.CENTER);
//Invoked by the applet browser only.
public void start() {
startAnimation();
//Invoked by the applet browser only.
public void stop() {
stopAnimation();
public synchronized void startAnimation() {
if (frozen) {
//Do nothing. The user has requested that we
//stop changing the image.
} else {
//Start animating!
if (!timer.isRunning()) {
timer.start();
public synchronized void stopAnimation() {
//Stop the animating thread.
if (timer.isRunning()) {
timer.stop();
public void actionPerformed(ActionEvent e) {
//Advance animation frame.
frameNumber++;
//Display it.
fgLabel.setLocation(
((frameNumber*5)
% (fgWidth + bgWidth))
- fgWidth,
(bgHeight - fgHeight)/2);
//Invoked only when run as an application.
public static void main(String[] args) {
Image bgImage = Toolkit.getDefaultToolkit().getImage(
MovingLabels.bgFile);
Image fgImage = Toolkit.getDefaultToolkit().getImage(
MovingLabels.fgFile);
final MovingLabels movingLabels = new MovingLabels();
JFrame f = new JFrame("MovingLabels");
f.addWindowListener(new WindowAdapter() {
public void windowIconified(WindowEvent e) {
movingLabels.stopAnimation();
public void windowDeiconified(WindowEvent e) {
movingLabels.startAnimation();
public void windowClosing(WindowEvent e) {
System.exit(0);
movingLabels.buildUI(f.getContentPane(), bgImage, fgImage);
f.setSize(500, 125);
f.setVisible(true);
movingLabels.startAnimation();
}
