Polymorhism: is a feature of OOPl that at run time depending upon the type of object the appropriate method is called.Inheritance: is a feature of OOPL that represents the "is a" relationship between different objects(classes). Say in real life a manager is a employee. So in OOPL manger class is inherited from the employee class. Encapsulation: is a feature of OOPL that is used to hide the information.

Polymorphism is the major pillar of OOPs and Java. There are two types of polymorphism static time polymorphism & dynamic type of polymorphism.

Static time polymorphism is called as" method overloading" & dynamic type of polymorphism is called as "method overriding".

When method call is resolved at compile time it is called as static time polymorphism & when method call is resolved at run time it is called as dynamic type of polymorphism.

In short polymorphism is the feature in which at run time depending upon the object appropriate method is called. This is all about polymorphism.

We can't create the object directly for the abstract classes,we can create object indirectly when we are inheriting that is called as polymorphism.

ex: abstract class man
   {

   }

   class women extends man
   {
   man m=new women;

   }
