Performing an action when an JMenuItem is clicked?

Question

So i have made a simple program with a basic menu at the top of the frame, Now i just need to put actions behind each JMenuItem. Im struggling to work the code out though, Here

Answer 1

Suggestion: Instead of adding a separate ActionListener, just use AbstractAction:

JMenuItem fileExit = new JMenuItem(new AbstractAction("Exit Program") {
    public void actionPerformed(ActionEvent ae) {
        JFrame hello = new JFrame("POPUP");
        hello.setSize(100,75);
        hello.setDefaultCloseOperation(hello.EXIT_ON_CLOSE);
        hello.setVisible(true);
    }
});

I'd also suggest, instead of setting EXIT_ON_CLOSE on the popup menu, you set it on the main frame of your application, and have the action simply call theMainFrame.dispose().
