I am trying to create a quiz program but each time I move to the new question I create a brand new frame each time. Is there any way that I can destroy the previous frame without having to start all over again.
Thanks..........code below.

import java.awt.event.*;

i wrote a quiz once. i stored the questions and answers in a file. it is an applet that talks with a servlet, but the code might help you.
