I want to design a JSlider to zoom in or out polygons.What I expected is the old drawing would be replaced the new drawing. Actually I use repaint() method, however I found the screen was mess up. The new and old pictures coexisted when I fired the event.
What is the reason it could be? I am sorry my code is too complex to make it as an example.

guess: you're not using getValueIsAdjusting(), but guesses rarely solve problems, so here's a basic program - add your code to reproduce the problem, then post back so we can see what you're doing.
