import java.awt.Graphics;
import java.awt.Image;
import javax.swing.JApplet;
public class Animate extends JApplet implements Runnable {
    Thread runner;
    boolean notDone;
    int x, y;
    public void init(){
        notDone = true;
        x = 10;
        y = 20;
        setSize(500,100);
        startRunning();
    public void run(){
        while(notDone){
            if(x < 400){
                x++; repaint();
                try {
                    Thread.sleep(500); // control the speed
                } catch (InterruptedException ex) {
                    ex.printStackTrace();
            } else {
                x = 10;
    public void startRunning(){
        runner = new Thread(this);
        runner.start();
    public void paint(Graphics g){
        animate(g);
    public void repaint(){
        try{
            Image img = this.createImage(getSize().width , getSize().height);
            Graphics g = img.getGraphics();
            g.setColor(this.getBackground());
            g.fillRect(0, 0, getSize().width, getSize().height);
            g.setColor(this.getForeground());
            paint(g);
            this.getGraphics().drawImage(img, 0, 0, null);
        }catch(NullPointerException e){}
    public void animate(Graphics g){
        g.drawString("Help me -->", x, y);
