Method Overloading is a feature that allows a class to have more than one method having the same name, if their argument lists are different. It is similar to constructor overloading in Java, that allows a class to have more than one constructor having different argument lists.

Today we are learning How method overloading is implement in java.

 import java.util.Scanner;

 public class function_overloading { //method number 1
    public static  int calc(int a){
        a=10;
        System.out.println(a);
        return  a;
    }

    public  static  int calc(int x,int y){ //method number 2
        System.out.println("Enter the value of x");
        Scanner sc=new Scanner(System.in);
        byte n1=sc.nextByte();
        System.out.println("Enter the value of y");
        byte n2=sc.nextByte();

        return n1+n2;

    }
    public  static  void calc(){   //method number 3
        String [] name=new String[5];
        name[0]="Ram";
        name[1]="Shyam";
        name[2]="Hari";
        name[3]="Sita";
        name[4]="Gita";
        byte j=0 ;//array index start with zero  to print all number on the array you should start the loop   form zero
        while(j<name.length){
            System.out.println(name[j]);
            j++;
        }

    }

    public static void main(String[] args) {

        calc(10); //calling method number 1
        //calc(10,20);//calling method number 2
        //to print the value of method number 2
        System.out.println(calc(10,20));
        calc();//calling method number 3
