Method Overloading in Java with Examples

In Object-Oriented Programming language, it comes with a lot of features. That is why most developers opt for object-oriented programming languages. These languages give great support to the developers. Methods are one feature offered by object-oriented programming language to the developers. Methods mean a feature that describes the object. Java language the famous object-oriented programming language also offers this feature called method. In Java also Methods are used to describe the behavior of an object. These are a collection of statements. These collections are a group which together to operate. It is possible to create methods of the same name in Java. But it has to be in different argument lists with various definitions.

Method Overloading in Java

In Java, Method overloading is possible. It is one of the unique features which is provided exclusively by Java. If a class in Java has a different number of methods, these all are of the same name but these have different parameters. Programmers can use them to perform different types of functions. This is called Method overloading. If one operation needs to be performed by a developer, which carries the same name, the readability of the method in the program increases.

If the user needs to multiply some numbers, for instance, two numbers, he can write as multi (int, int) with two parameters, or can multiply three numbers with multi(int, int, int) with three parameters, and so on. By using the method of overloading the developer can complete the task easily and efficiently. In a program, if the objects are required to perform a similar task but there are different parameters, method overloading is applied. When an object is called by a method in java, it matches up with the method name first, and next, it decides the number of parameters and types of parameters which helps in deciding what are the definitions to execute. Method overloading can be done in different ways in Java. The three main types of method overloading in Java are:

Based on number of Parameters
Based on data type of Parameter
Based on series of data types in Parameters

If the whole method overloading process depends on the number of parameters that are placed within the deviations of the method is the process based on the number of parameters. In the process of the data type of parameter, it will take place inside the parameter, with the arrangement of data type. In the sequence of data types in parameters, method overloading depends on the ordering of data types parameters that are within the method.

Benefits of Method Overloading

Method overloading gives huge benefits to the users. As it is a unique feature of the Java programming language, it offers easy and smooth working of projects by developers. Let us look at some of the benefits offered by Method overloading to the developers.

It helps in increasing the readability of the program
Provides flexibility to the Programmers
Programmers can call the same method for different data types
It makes the code looks clean
Reduces execution time
Binding can be done in compilation time
It minimizes the complexity of the code
The codes can be used again
Frees memory

Method Overloading in Java Examples

Method overloading example if changing number of arguments.

Class Adder{

Static int add (int a,int b) {return a+b};

Static int add (inta , int b, int c) {return a+b+c};

Method overloading example in type promotion

classOverloadingCalculation1{

Void sum(int a, long b){System.out.printIna+b;}

Void sum (int a,int b,int c){System.put.printIna+b+c;}

Function Overloading in Java

If the functions have the same name and different numbers, function overloading will be done in Java. It is used for reducing the difficulty of the project and to increase efficiency. If more functions are involved in a program, function overloading helps to distinguish among each other based on their respective individual personality. Overloaded functions are related to static polymorphism.

Conclusion

Method overloading or Function overloading is an overloading function which exclusively offered by java to its programmers. It helps in reducing the complexity of the program and also gives the ability to improve efficiency.
