First, a bit of business: you may not have read our naming policy on the way in. It requires that you use a full, real (sounding) first and last name for your display name. Initials aren't enough. You can change your display name here. Thanks!
Now, as to your question: what you have is a method returning void with the same name as a class. That's not a constructor -- constructors don't have a return type, and you also can't call them directly. You can only call them using "new" or "super". In your OverRide class, that is a constructor.
