04. What is polymorphism in programming?

Polymorphism is the capability of a method to do different things based on the object that it is acting upon. In other words, polymorphism allows you define one interface and have multiple implementations. I know it sounds confusing. Don’t worry we will discuss this in detail.

 1.   It is a  feature that allows one interface to be used for a general class of  actions.

 2.   An operation may exhibit different behavior in different instances.

 3.    The behavior depends on the types of data used in the operation.

 4.    It plays an important role in allowing objects having different internal structures to share the same external interface.

 5.    Polymorphism is extensively used in implementing inheritance.

Following concepts demonstrate different types of polymorphism in java.

1) Method Overloading
2) Method Overriding
