Answer / ajay roy
Abstract Class is the one which contains atleast one
abstract method and other method may not be essentially
abstract. However, interface always have only method
signature in it. We can not have methods with
implementation in interface unlice abstract class.
When designer wants to use common property of a system then
he should go with abstract method. Because in abstract
method he can have implementation of common properties
along with signature of other method which can be
implemented as per need.
