Answer Posted / avinash
In Real time,we use Abstract class when we want the
implemented functionality to be used . In Abstract class ,
there may contain Abstract methods or non abstract
methods(concrete methods).
When we dont want the functionality provided by the abstract
class then we are going to make use of Interface. we
directly implement the interface and provide functionalities
for the abstract methods.
