Polymorphism meaning "one name many forms", which is also referred to as the third pillar of object-oriented programming. "Poly" means many and "morph" means forms. Polymorphism provides the ability to a class to have multiple implementations with the same name.

Types of Polymorphism
Polymorphism can be static or dynamic. In static polymorphism, the response to a function is determined at the compile time. In dynamic polymorphism, it is decided at run-time.
Static Polymorphism
Static polymorphism is also known as Early Binding. We can achieve this by Method overloading. In overloading, the method / function has a same name but different signatures (types and/or the number of arguments and/or order of arguments). It is also known as Compile Time Polymorphism because the decision of which method is to be called is made at compile time.
