Polymorphism

-- Concept of exhibiting different behaviours in different situations by a method is known as polymorphism.

There are 2 types of polymorphism.
1.Method or static polymorphism
2.Object or dynamic polymorphism

Static polymorphism :

              --  Here the same method will give different result based on the arguments that we are passing so this is known as method polymorphism.
              -- which method has to be executed will be decided by the compiler during the compilation is known as static polymorphism.
              --  We can achieve the method polymorphism using method overloading.
             -- compiler it self will decide which method has to be executed first is known as“StaticPolymarphism”

 Method overloading or method overwriting:-
                                       --Concept of defining a method with same name and with different signatures is known as method overloading.


Dynamic Polymorphism :

              -- Same method will give different result based on the object acting upon it.(object polymorphism)
              -- In this case which method has to be executed will be decided by the jvm during runtime(dynamic)
              -- We can achieve dynamic polymorphism by using method overriddenig.

Method overriding :
              -- Concept of defining the same method with same signature inside the subclass.
