Abstract Class encapsulates shared(common) behavior and
define place holder for all subclasses
- Define shared behavior
- Can have implementation code
- Can not be instantiated
- A class can be inherited from single abstract
class—Unless language supports Multiple inheritance.
- Provide both abstract and concrete menthods
- Strict IS-A relationship.
Interface: If there is no shared behavior –each subclass
must implement all method defines in a base class this is
called as Interface
- Defines Behavior. It is a cntract and its subclass
must implement it.
- Can not be instantiated
- A class can implemet mutiple interfaces
- Provide only abstract methods
- Not a strict IS-A relationship
