    I have a question about something that has puzzled me. I did this
    on my program because it was how I saw it done. I was wondering if
    someone could explain why it is done this way and if I would do this for
    all ActionEvents.

    I used the following code. What does the ".getSource()" do? Is that
    what registers when someone clicks the button? How would this format
    change if I was adding data entered into a text field? Any help is much
    appreciated!! :)


    public void actionPerformed(ActionEvent e)
    if (e.getSource() == b)
    if (click == 1)
    b.setText("I've been clicked!");
    b.setText("I've been clicked " + click + " times!");
