Java Program to add two numbers using Scanner

Logic : int c = int a + int b

In this Java Program, we use the Scanner class to get the numbers from the user.  

Step 1 : Create 3 variables named as num1, num2 and sum. 

Step 2 : Insert Scanner Class for taking the input from the user.  

Step 3 : Use System.out.println method to take input of first number from the user.

Step 4 : Store the user's input in variable num1

Step 5 : Use System.out.println method to take input of second number from the user.

Step 6 : Store the user's input in variable num2

Step 7 : Close the Scanner.

Step 8 : Perform the addition of the two numbers entered by the user with the help of  "+" operator and store the result in the variable named as sum.

Step 9 : Display the result by using the System.out.println method. 

Program :

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
