Java program to demonstrate example of method overloading.
Consider your method as a Donkey, and we are overloading our method, that is we are giving same method different tasks to do based on parameter, and then we say that the method is over loaded. Need Of Method Overloading: Firstly let us discuss how Method overloading comes into picture and makes our task much easier.
Example of Method overloading with type promotion. Java supports automatic type promotion, like int to long or float to double etc. In this example we are doing same and calling a function that takes one integer and second long type argument. At the time of calling we passed integer values and Java treated second argument as long type.
Method Overloading: When multiple methods in the same class with same name, having different functions or types of parameters, it is known as Method Overloading. When an overloaded method is invoked, it is the responsibility of the compiler to select the appropriate overloaded method based on the number of argument(s) passed and if the numbers of argument(s) are same then depending upon the.
Java Constructor Overloading Examples. Like method overloading we can overload constructors also. Along with default constructor, we can have constructors with parameters. The no of parameters can be same, and it can have different datatypes. Below example gives sample code for constructors overloading. Java Constructor Overloading Sample Code.

A Java method is a collection of statements that are grouped together to perform an operation. When you call the System.out.println() method, for example, the system actually executes several statements in order to display a message on the console. Now you will learn how to create your own methods with or without return values, invoke a method with or without parameters, and apply method.
Method Overloading is creating a method with the same name as an existing method in a class.Hence in simple words, method overloading allows us to have multiple versions of a method within a class. Why method overloading is used? Method overloading is mainly used in a situation when we want to create multiple specialized versions of a method in a class, with each version having the same name.
