Java – How to add a JOptionPane for Yes and No options

actionlistenerjavajoptionpaneswing

So, I've read the Java API, but still can't seem to make heads or tails about how to do this. And believe me I have tried. I want an ActionListener to cause a message box with the text 'Do you really want to exit?', with options yes and no which exits the program or not depending on the selected button.

Here's what I have for the ActionListener before I started to break it with the message box:

exitItem.addActionListener(
                new ActionListener() {
                    public void actionPerformed(ActionEvent arg0) {
                        window.dispose();
                    }
                }
                );

How can I suitably change it to meet my requirements?

I think you want to do something like this inside your ActionListener:

int selectedOption = JOptionPane.showConfirmDialog(null, 
                                  "Do you wanna close the window?", 
                                  "Choose", 
                                  JOptionPane.YES_NO_OPTION); 
if (selectedOption == JOptionPane.YES_OPTION) {
    window.dispose();
}
