Method Overloading in Java Programming

Method overloading is a form of static polymorphism. In method overloading, we can define multiple methods with the same name but different parameters. See the following example program.

Example

public class Tester {
　　　public static void main(String args[]) {
　　　　　　Tester tester = new Tester();
　　　　　　System.out.println(tester.add(1,　2));
　　　　　　System.out.println(tester.add(1,　2,3));
　　　}
　　　public int add(int a, int b) {
　　　　　　return a　+　b;
　　　}
　　　public int add(int a, int b, int c) {
　　　　　　return a　+　b　+　c;
　　　}
}

Output result

3
6

In this case, we use a methodadd()This method can use two or three parameters and perform operations accordingly. This is called method overloading or static polymorphism.
