Java Program for the Sum of two numbers

//Addition of two numbers
 
 public class AddTwoNumbers 
 {

   public static void main(String[] args) 
   {
        
     int num1 = 20, num2 = 30, sum;
     sum = num1 + num2; //adding two numbers

     //Display result
     System.out.println("Sum of num1 and num2: "+sum);
   }
}

Output:

Sum of num1 and num2: 50

Java Program for the Sum of two numbers using Scanner

The Scanner class is used to get the inputs from the users in Java programming. We need to import a scanner class at the beginning.

import java.util.Scanner;
public class AddTwoNumbers
{
  public static void main(String[] args)
  {
    int num1, num2, sum;
    Scanner sc = new Scanner(System.in);

    //Taking Inputs from Users
    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:
10
Enter Second Number:
5
Sum of these numbers: 15
