Basic JButton and ActionListener Problem 1

Thanks for reading (more of a personal question than a professional one)

I have just starting to use java and wanted to start writing a simple "Who wants to be a millionaire" java game.

Using the few texbooks that I have i've managed to write a small part of the program, but I can't seem to get the button to return the correct value (getanswer) elsewhere in the program. The program compiles fine, but doesn't actually do anything.

Any ideas would be very helpful

Well, I'm not really experienced using applets, and have no idea why it won't work in appletviewer.

There was a large reason why nothing was being displayed though - there was no JFrame to display the contents of the Container object. So I've added that, and by running the class as a standalone class, some stuff now pops up. So type "java -cp . allornothing" and you'll see something ...

Code: 
import java.applet.Applet;

public class allornothing extends JApplet implements ActionListener {

Thanks Prosper

I've changed the program a little bit more using your code for the ActionListener. The problem i'm haveing now is trying to figure out how to get the running total for the score working

If anyone has any thoughts
