    event listeners

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

    At present, I only have the ActionListener like this:

    PHP Code:
    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).
    Code:
    public class Calculator extends Applet implements ActionListener, KeyListener
