2. Sum of two numbers using Scanner :-

# The scanner allows us to capture the user input so that we can get the values of both the numbers from user. The program then calculates the sum and displays it.

	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:
	200
	Enter Second Number:
	300
	Sum of these numbers: 500
