This Java program adds two integers given in the program and displays the result on the screen.
To understand the topic, you need to have a basic understanding of two basic topics in Java.
Java Program for the Sum of two numbers
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | //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.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | 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
