Answer / jasbir singh
An abstract class is a class with at least one function
without definitions.
An Interface is a class which only contains function
declarations, all the functions are specifically and
separately defined later. And you can't create objects of
these classes.

Answer / poorna chandar rao
diffrence bettwen the abstract class and interfaces
abstract class is having abstarct methods and concrete
methods abstarct class as compulosry having subclass for the
implementation abstarct methods and abstarct does not
support multiple inheritence
because one subclass extend the abstract class their is no
scope for extends for another class because it is not
support for the multiple inheritence
ex 1: abstract class one
2 class two extends one extend three (not valid)
but interface having only method signature in the interface
their is concrete method and it supports the multiple
inhirtence because
ex: interface one
class two implements one extends three(valid)
onc class implemens the interface and extends to another
class that is support the multiple inhertince
