What are the 4 types of polymorphism?

Polymorphism is one of the OOPs feature that allows us to perform a single action in different ways . For example, lets say we have a class Animal that has a method sound() . Since this is a generic class so we can’t give it a implementation like: Roar, Meow, Oink etc. We had to give a generic message.

Ad-hoc, Inclusion, Parametric & Coercion Polymorphisms

In simple words, we can define polymorphism as the ability of a message to be displayed in more than one form . A real-life example of polymorphism, a person at the same time can have different characteristics. Like a man at the same time is a father, a husband, an employee.
