PROBLEMS With my FOR LOOP , PLEASE HELP!!!

Question

Hello,
I have the following event action button method. It has a loop itterates 10 times. I have an imagePanel of a map with an image of a car over the map. The car image moves with the method moveCar();
MY PROBLEM: even though i have my moveCar() method inside the for loop, it doesnt move the car on the map until the loop is finished executing and the car image just jumps over. Can somebody pleae tell me why it does this and how to fix it?????????? thanks so much       public ActionListener startActionListener() {
         ActionListener listener = new ActionListener() {
         public void actionPerformed(ActionEvent event) {
         for (int i=0; i<10; i++) {
                         imagePanel.moveCar();
                    try {
                         Thread.sleep(1000); //waits approx. 1 second
                    } catch (InterruptedException e) {
                         System.exit(0);
           return listener;
     }thanks!

Well, the easiest way is like this:
public ActionListener startActionListener()
     ActionListener listener = new ActionListener()
          public void actionPerformed(ActionEvent event)
               new Thread(new Runnable()
                    public void run()
                         for (int i=0; i<10; i++)
                              imagePanel.moveCar();
                              imagePanel.repaint();
                         try
                              Thread.sleep(1000); //waits approx. 1 second
                         catch (InterruptedException e)
                              //System.exit(0);
               }).start();
          return listener;
}I simply converted your loop to run asynchronously and added a call to repaint after the move. You would be better off to use a Swing Timer instead, but I will leave that to you.
