Object Oriented Programming - Inheritance

Expert: Marty Landman - 7/1/2009

Question
What is inheritance in detail with one fair example.

Answer
Pavan,

Inheritance is a way to provide reusability automatically and in a common sense way. For instance, there might be a class of members, with methods defined for

member.info
member.blog

Now if you define a subclass of member called premium_member then as a subclass of member, premium_member inherits all the member methods. Therefore you have info and blog methods automagically available for premium_member's.

Hope this is helpful.
