You have to use jframe and then

JFrame AFrame = new JFrame("Frame with components");
AFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

But if you insist on Frame, add a listener:

AFrame.addWindowListener(new WindowAdapter() {
    public void windowClosing(WindowEvent e) {
        System.exit(0);
    }
});
