Polymorphism is considered one of the important features of Object-Oriented Programming. Polymorphism allows us to perform a single action in different ways. In other words, polymorphism allows you to define one interface and have multiple implementations. The word “poly” means many and “morphs” means forms, So it means many forms.
Types of polymorphism
In Java polymorphism is mainly divided into two types:
Compile-time Polymorphism
Runtime Polymorphism
Compile-time polymorphism
It is also known as static polymorphism. This type of polymorphism is achieved by function overloading or operator overloading.
Note: But Java doesn’t support the Operator Overloading.
Method Overloading
When there are multiple functions with the same name but different parameters then these functions are said to be overloaded. Functions can be overloaded by change in the number of arguments or/and a change in the type of arguments.
