WHY IMPLEMENTATION INHERITANCE IS BAD.

There are two types of Inheritance.

§ Implementation inheritance: Implementation inheritance allows a super class and a subclass to share identical code for the same method.

§ Interface Inheritance: inheritance wherein one or more classes share a set of messages.

Multiple Inheritance

Both Car and Boat classes inherit from vehicle supper class. Here Car and Boat are child classes.
