{
    final void m1() 
    {
        System.out.println("This is a final method.");
    }
}

If you are coding smth for yourself, or a GUI application, for example, you'll probably never need to make your methods final. But, if you are making a library, and making some core functionality that you don't want to be changed by other programmers who will use it, you can use final keyword.
