Question

Write a program the user must input two numbers then you print sum by calculating or adding the two numbers

Answer 1

Answer:

public class AddTwoNumbers {

  public static void main(String[] args) {

       

     int num1 = 5, num2 = 15, sum;

     sum = num1 + num2;

     System.out.println("Sum of these numbers: "+sum);

  }

}

We can also use scanner-

import java.util.Scanner;

public class AddTwoNumbers2 {

   public static void main(String[] args) {

       

       int num1, num2, sum;

       Scanner sc = new Scanner(System.in);

       System.out.println("Enter First Number: ");

       num1 = sc.nextInt();

       

       System.out.println("Enter Second Number: ");

       num2 = sc.nextInt();

       

       sc.close();

       sum = num1 + num2;

       System.out.println("Sum of these numbers: "+sum);

   }

}

Output:

Enter First Number:  

121

Enter Second Number:  

19

Sum of these numbers: 140
