Answer Posted / muthusenthil
Abstract(patially implemented) class can be used as a
common base class for an application it has all property of
class except it cannot be instantiated.it provide default
behavior.
interface is mearly a specification,nothing implemented for
any standalone project which can be changed at will its
more design flexible and it can be utilized to model
multipleinheritance.
