ActionListener/Action Performed

Question

Ok so, ive got my GUI to display using multiple layouts thanx to all of your help!!!! Thanx so much....Now to make the GUI do stuff. My question is, in all of my other classes, i have already written fucntions that will be tied to buttons (ie, add user[writes to db], delete user, etc), but my question lies with how do i properly implement actionListener and ActionPerformed.
Ive been looking at this tutorial:
http://java.sun.com/docs/books/tutorial/uiswing/events/actionlistener.html
public class Beeper ...  implements ActionListener {
    //where initialization occurs:
        button.addActionListener(this);
    public void actionPerformed(ActionEvent e) {
     Toolkit.getDefaultToolkit().beep();
}my question is, since i have four buttons, am i supposed to have a seperate actionPerformed() version for each button? Or Can i write one huge actionPerformed() that tells java what to do with all of my buttons (in tieing the buttons to my functions)...? Any help is greatly appreciated.

Not sure what you mean. The source is the component that fired the ActionEvent that has been sent to the listener. If a button gets clicked, the button is the source.
If, on a button click, you want to know what is in a text area, use myTextArea.getText().
For example, the text area contains a name, but the action you want to perform is based on wether you click the "DeleteName" or "AddName" button. Get source tells you which button is clicked. Then, you get the text and call the appropriate function. That is why you have an if/else construct in the actionPerformed() method.
