but every time i click the exit in
the frame.. it won't exit.. :(
PLS help me to add some codes in exit...

You need to add an actionlistener to your button. At the moment it is doing nothing when you click the button because you haven't programmed it to do anything.

Because you didn't attach any event (listener) to the button click event.

Code:

---

button .addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(ActionEvent e) {
                System.exit(0);
            }
        });

If you click the red cross button at the top right of the JFrame the application exits. If you press your JButton nothing happens, no matter if you label it "Exit" or "Quit" or whatever. Read about ActionListeners.

kind regards,

Jos

edit: darn, much too slow again ;-)

Then see the above reference tutorials (and actually read them don't just cut-n-paste code) so that you know how to use what it is you cut-n-pasted from that post, which you obviously don't know how, yet.

Just without copy and past what I've post, you must look at it first of all and find what it's really means and how it should used.
