event listeners

[hga77]

I have a calculator class. I need this class to use both KeyListener and ActionListener.

At present, I only have the ActionListener like this:

public class Calculator extends Applet implements ActionListener 

But how can I use the KeyListener too?

just add it on, you can implement as many interfaces as you like (only use the "implement" keyword once though).

public class Calculator extends Applet implements ActionListener, KeyListener
