Message pop up when program ends

Is there any way to have a JOptionPane.showMessageDialog pop up when you end the program? I am wanting to display a log of users who have logged into my program during that specific run. I have the code completed for displaying the message, just am not sure as to how to get it to display when the program ends.

Thanks

Solution

  • You can either add a listener to whatever event closes the application. You can use a WindowListener to detect when people click the X. Tutorial here: http://docs.oracle.com/javase/tutorial/uiswing/events/windowlistener.html

    Or you can look into shutdown hooks.
