Overloading in Java with simple example

Overloading in Java 

In Java, If two or more methods in a class have the same method name but different parameters, the methods are defined as different methods even though it has the same method name. 

simple example code

class Calculator {
    int a, b, c;
 
    public void setCal(int a, int b){
        this.a = a;
        this.b = b;
    }
    //same method name with different parameters
    public void setCal(int a, int b, int c){
        this.a = a;
        this.b = b;
        this.c = c;
    }
   
    public void sum() {
        System.out.println(this.a + this.b + this.c);
    }
    
    public void avg() {
        System.out.println((this.a + this.b + this.c) /3);
    }
}
 
public class CalculatorConstructorDemo5 {
    public static void main(String[] args) {
        Calculator cal = new Calculator();
        cal.setCal(10,30);
        cal.sum();
        cal.avg();
        cal.setCal(10,30,15);
        cal.sum();
        cal.avg();
    }
}
