Overloading is the compile time polymorphism and overriding is the runtime polymorphism. Method overloading and overriding in other words polymorphism in java is neither a very difficult concept and nor it s one of very unknown topics yet i am bringing this topic here in this post because at the same time it is very easy to make mistakes when such concepts are tested in java interviews using multiple code examples. Let us discuss some of the major key differences between overloading vs overriding.

This can be of either overloading or overriding. Creating a method in the derived class with the same signature as a method in the base class is called as method overriding. Similar to method overloading we also have some mandatory and optional rules we need to follow to override a method.

Creating more than one method or function having same name but different signatures or the parameters in the same class is called method overloading. Method overriding is a run time polymorphism. Polymorphism is a major concept in object oriented programming.

Going to an interview we can not afford to not know the difference. In method overloading methods can have the same or different access specifiers modifiers in the method name whereas in method overriding method of base case overridden method must have restricted access specifier than the method of a parent class. While it is used to grant the specific implementation of the method which is already provided by its parent class or super class.

Method overriding method overriding means defining a method in the child class which is already defined in the parent class with same method signature i e same name arguments and return type after java 5 you can also use a covariant type as return type. The real object type in the run time not the reference variable s type determines which overridden method is used at runtime in contrast reference type determines which overloaded method will be used at compile time. Key differences between overloading and overriding.

Here are some important facts about overriding and overloading. As you will see in the example below method overloading gives us the ability to have multiple methods with the same name and same or different return type.
