What is Polymorphism

=>Polymorphism is one of the principle of object oriented programming. "Poly" means many and "morph" means forms hence the name polymorphism.

=>Polymorphism also refered to as one name many forms or having one name with multiple functionality.

=>Use same method name with different signature or same signature but in different class.So depending on a data type it processes objects differently and an ability to redefine methods for a derived classes.
