5 Difference Between Method overloading And Method Overriding

Method overloading and method overriding is used when more than one method in a class have same name with different parameters it is known as overloading. And when name and parameters are same in sub or superclass is known as overriding. Both of these terms used in the programming languages. Both of these methods of overloading and method of overriding is very important in same or duplicate cases in the programming.

Both of these terms are used in the difference duplicate or same case. In this article we will discuss about their definition and main differences between method overriding and method overriding.

Method overriding vs method overriding

Sr.no	Method Overloading	Method Overriding
1	For method overloading class must have same name but different parameters.	in method overriding class should have same name and parameters.
2	Method overloading is mainly used to increase readability of the program.	overriding is used for the specific implementation for program.
3	Overloading is used within the class.	overriding is used between two classes which have inhabitance relationship.
4	Overloading is a example of compile time polymorphism.	Overriding is a example of run time Polymorphism.
5	Overloading is add or extend more to method’s behavior.	Overriding is complete change the behavior of method.

Method overloading

when more than one method in a class have same name with different parameters it is known as overloading. Method overloading is also known as compile time polymorphism and functional overloading. There are many languages which supports this method overloading feature these languages are C++, C#, Java and D

Method overriding

when name and parameters are same in subclass, child class or superclass is known as overriding. Method overriding is also known as the Run time Polymorphism and Functional overriding. This method allows a sub or superclass to provide its own implementation. The allowed implementation overrides the definition of assigned method in the base class.

Main difference between Method overloading and method overriding

1. For method overloading class must have same name but different parameters. While in method overriding class should have same name and parameters.
2. Method overloading is mainly used to increase readability of the program. While overriding is used for the specific implementation for program
3. Overloading is used within the class. While overriding is used between two classes which have inhabitance relationship.
4. Overloading is a example of compile time polymorphism. And overriding is a example of run time Polymorphism.
5. Overloading is adding or extend more to method’s behavior. while overriding is complete change the behavior of method.

Conclusion

Method overloading and method overriding two terms which are used in the object programming. Both these terms are used to enhance the reusability and readability of the program. Method overloading and method overriding is very important in the programming of the objects and the programs. To understand this this is very important to understand interface and class.
