WindowAdapter In Inner Class

Question

I\'m working on a Java school assignment, thought I had it all finished, but then went over the requirements one more time and realized I overlooked a specific requirement and n

Answer 1

looks like you got everything right!

Now what I assume your teacher means is: the handler should be an instance (not "object") of an inner class that extends the WindowAdapter class.

By doing the following:

new WindowAdapter() {

    // Use annotations, it's useful :)
    @Override
    public void windowCloses(WindowEvent e) {
        // ...
    }
}

... you're actually creating a new anonymous class that extends WindowAdapter. In this new definition, you override the WindowAdapter#windowCloses method, then you instantiate it in a new object that you pass as an argument to addWindowListener.

Apparently, your teacher expects you to actually define an inner class and create a new instance of it. I don't wanna just give you the code for this but you're god damn close, you'll figure it out in an instant!
