How do I simplify MouseListener so that I don't have all these unused methods?

Question

Below I have the following code, so that when someone clicks on the \"Close\", the window will close. Below that is another exit button on the same menu bar, simply for redundan

Answer 1

Use a MouseAdapter and override the methods that you want.

closeFile.addMouseListener(new MouseAdapter() {
        public void mouseClicked(MouseEvent arg0) {
            System.exit(0);
        }
    });
