OnExit Event For a Swing Application?

Question

I\'m developing a simple application to manage the operational part of a business using Swing, but I need that when the application exits, it performs this:

Answer 1

Runtime.getRuntime().addShutdownHook(new Thread()
{
    @Override
    public void run()
    {
        updateZonas();
        db.close();
    }
});

This works for any Java application(Swing/AWT/Console)
