Ability of an object to take
Many forms. Any object in java that passes IS-A test is polymorphic and since all objects extends Object class hence all object are polymorphic.

To implement polymorphism in java we have 2 ways :
Static can be implemented by overloading
Dynamic can be implemented by Overriding

If child class has same method (with same signature) as defined in parent class is overriding
A process in which a call to overridden method is resolved at runtime rather than compile time.

Methods having same names but different Parameters is method overloading. Eg
Add(a,b) and Add(a,b,c)
Both methods add all arguments
