Answer Posted / gopi
abstract class means--it has atmost one abstract
method.remaining might be abstract or not.
interface means ---it has almostall abstract methods.u have
only the method specification.
In real time if u want to share the some common features in
the abstract class u have to extends the abstract class.
so, u need not wrote the body to the all the methods.
if u implement interface u should write body to the all
the methods.
