IntroductionOverriding and overloading are the core concepts in Java programming. They are the ways to implement polymorphism in our Java programs. Polymorphism is one of the OOPS Concepts. Show
When the method signature (name and parameters) are the same in the superclass and the child class, it’s called overriding. When two or more methods in the same class have the same name but different parameters, it’s called overloading. Comparing overriding and overloading
Overriding and overloading exampleHere is an example of overloading and overriding in a Java program:

ConclusionIn this article, we covered overriding and overloading in Java. Overriding occurs when the method signature is the same in the superclass and the child class. Overloading occurs when two or more methods in the same class have the same name but different parameters. Is it possible for a subclass to define a method with the same name and parameters as a method defined by the superclass?A subclass must define all the methods from the superclass. It is possible for a subclass to define a method with the same name and parameters as a method defined by the superclass.
Can a subclass have a method with the same name?If your subclass defines a method with the same name and signature as a method in its superclass, the method in the subclass overrides the one in the superclass. Thus, the subclass does not inherit the method from its superclass.
Can a subclass have a method with the same name and the same signature as its superclass?You can write a new instance method in the subclass that has the same signature as the one in the superclass, thus overriding it. You can write a new static method in the subclass that has the same signature as the one in the superclass, thus hiding it.
Can a subclass have its own method?A subclass can do more than that; it can define a method that has exactly the same method signature (name and argument types) as a method in its superclass.
