1)If we r having 2 classes, both classes need a method with
same business logic(definition). Then we can go for an
abstract class. In this abstract class we can define the
method with functionality. And the two classes will extend
this abstract class.
2)In other case if two different classes wants two different
functionalities with same method name , then we go for an
interface with abstract declaration of method.And the two
classes will implement the interface and override the method
with different business logic
