Answer Posted / meraj khan
Abstract class:
Abstract class act as base class, not instantiable, no
implementaiotn in base class but allow implementaiotn in
derived class with overide method, method must be abstract.
specially used in inheritance.
Interface:
Interface class dont have constructor, destructor,
always public modifier set to true
no implementation
cant used multiple inheritance instead of this we use
multiple interface
