Answer 1

Your program:

import java.util.Scanner;

class test

{

   public static void main(String[] args)

   {

       Scanner sc = new Scanner(System.in);

       System.out.println("Enter first number: ");

       double n1 = sc.nextDouble();

       System.out.println("Enter second number: ");

       double n2 = sc.nextDouble();

       long n3 = (long)n1+(long)n2;

       System.out.println("The sum of the numbers: "+n3);

   }

}
