Question

(This is for Java)

I have to write a code that takes three numbers entered from the keyboard and adds the three numbers.  
But for this, I need to use the sum() method

Answer 1

SOURCE CODE IN JAVA:

import java.util.Scanner;
public class Main {
  public static void main(String[] args)
    {
        Scanner in = new Scanner(System.in);

        System.out.print("Input first number: ");
        int x = in.nextInt();
        System.out.print("Input second number: ");
        int y = in.nextInt();
        System.out.print("Input third number: ");
        int z = in.nextInt();

        int ans = Integer.sum(Integer.sum(x,y),z);
        System.out.println("Sum of three numbers is : " + ans);
    }
}
