30. Overriding static method    coderanch.com

I may be way off (since I'm only a beginner) but the first thing that jumped at me from your code is the fact that you made the doStuff() method from your subclass protected which as far as I know limits it's scope of visibility compared to the same method from your superclass.

Kaj- thanks for you reply. I think I was a bit unclear in my first post.

Is there a common work-around to achieve this ? Yes, use objects (instances) and abstract methods, if you use (pure) Java.

39. Why we cannot override a method marked as static ?    forums.oracle.com
