How to Remove Flashing in an Applet

Most of the Java books talk about double buffering for removing the flashing. It solves the problem to some extent but not 100% perfect in case of flashing. I am giving the following tricks to solve the flashing problem in animation :

1) Use Media Tracker for downloading the images.
2) Use double buffering.
3) Change the default background color of the applet to the color of you Canvas by using setBackground(Color of the Canvas) in the init method of the applet.
4) In an animation if you are updating only part of a area use repaint(x1,y2,x2,y2) instead of repaint().
