Paint in Java!

Hi,

I have a small problem in RE-draw any image!

I mean when I replace any image with other

the screen goes white for a sec then the other image appears.

thanks,..

Moin Moin,

i hope i'm not too late.

Look at this...

public class PetePanel extends JPanel implements Runnable
{
	MediaTracker tracker;
	Image[] petePics = new Image[6];
	Image back;

	public PetePanel()
	{
		setBackground(Color.black);
		String[] peteScr = {"right1.gif", "right2.gif", "right3.gif",
									  "stop.gif" , "blink.gif", "wave.gif"};

		Toolkit kit = Toolkit.getDefaultToolkit();

		tracker = new MediaTracker(this);
		for (int i = 0; i < petePics.length; i++)
		{
			petePics[i] = kit.getImage(peteScr[i]);
			tracker.addImage(petePics[i], i+1);
		}
		back = kit.getImage("backdrop.gif");
		tracker.addImage(back, 0);
	}

	public void paintComponent(Graphics comp)
	{
		Graphics2D comp2D = (Graphics2D) comp;
		if(back != null)
			comp2D.drawImage(back, 0, 0, this);
		comp2D.setColor(Color.black);
		comp2D.fillRect(0, 30, 450, 30);
		if(petePics[current] != null)
			comp2D.drawImage(petePics[current], x, y, this);
	}
   .
   .
   .
}

in the main or run function call at first
		try
		{
			tracker.waitForAll();
		}
		catch (InterruptedException ign) {}

Thats it.

I have used :

repaint(X,Y,W,H);

to re-draw the images
