Question: The real time environment , when do we go for abstract class and when do we go for interfaces , can any one please revert back in this regard?

Answer: Interface is the one which can be implemented by many number of methods in different classes as it requires, so there may be a chance that u may have some functionality which wil be need for many methods , in that case u u use interface to declare

Abstract class is the one which can implement more than one of this kind of interfaces but only the conditon is that all of its methods sud be implemented in the subclasses
