Abstract class: We no need to create the object for the
abstract class, abstract class must be sub classed.
Abstract class may contain its default implementation.
Interface: It is just like a check list. All the methods is
interface should be a public.It contain only the method
declaration. If one class implements the interface means,
that class should give the implementation for the all the
methods.
