Let’s see a simple program to add two numbers:

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);
   }
}

Output:

Sum of these numbers: 20

Let’s see another example in which we get the values from user.

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: 
110
Enter Second Number: 
19
Sum of these numbers: 229
