When should we use abtract class and Interface Class?Give an Example..

Answer / pallavi

Use an abstract class when you want to inherit only from the parent
Use an interface when you want to inherit from multiple sources
If the behaviour of base class is default behaviour of all the sub classes the use abstract. If it is not default behaviour for all the classes use interface.
Interface - CAN-DO relationship
abstract class - IS-A relationship
