>>What is meant by Supper Class.
Nabil,

I am sure you have gotten the joke by now :-), the words super and supper are very similar. Supper is one word in English that refers to the evening meal.

In answer to your actual question, what is meant by super class, superclass is the actual terminology that is used in object oriented design to refer to the parent class of another class. If I create a class named MyClass and then I create a class that is subclassed from Myclass named Myclass2, then MyClass is the superclass for MyClass2, it is possible that MyClass2 may also be the superclass of MyClass3.

Microsoft uses the term ParentClass for the same thing. ParentClass and SuperClass are interchangable terms.
