Polymorphism

Polymorphism means taking many forms, where ‘poly’ means many and ‘morph’ means forms. It is the ability to allows us to perform a single action in different ways. Polymorphism in Java is of two types: 

• Compile time polymorphism( or Static Polymorphism)
• Run time polymorphism (or Dynamic Polymorphism)

We can perform polymorphism in java by :

1. Method overloading (Compile time polymorphism)
2. Method overriding (Runtime polymorphism)
