Answer / harikrishna
you never get a chance to choose a method from abstract
class,because if you are writing a abstract class you
have to provide implementation to all the methods in
subclass otherwise you should declare that subclass as
Abstractclass.

Answer / madhav
Interface is preferable to Abstract class as when ever in
instance is created for subclasses of this,constructors
will be called hirarchially consuming some time for each
constructor call..

Answer / ashoka
Better to choose Abstract class. Because it contains not
only the abstract methods but also implemented methods but
in interfaces only unimplemented methods will be there and
all final variables will be there.
