Java tutorial for beginners || Method Overriding in Java || Runtime Polymorphism in Java ||

The word “poly” means many and “morphs” means forms, so Polymorphism means many forms.
In Simple terms executing same method in more than one form. For example, a “print” message would produce very different results, depending on the object it is sent to. This property of objects that, different objects can respond to same message in different ways is called Polymorphism

Types of Polymorphism

In Java Polymorphism is of two types

1. Compile-time Polymorphism
2. Runtime Polymorphism


In Java Method Overriding is a feature that allows a subclass/child class/derived class to provide a specific implementation of a method that is already provided by one of its super classes or parent classes.

The method implementation in the subclass overrides the method implementation in the superclass only when we follow below rules

1. Method name should be same in Parent and Child class.

2. Must have same arguments in Parent and Child class (Arguments depends on datatype, datatype count, datatype order)

3. Must have same return type as the method in the parent class.

4. Methods declared as final cannot be overridden.
