Add Two Numbers in Java - The Coding Shala

Home >> Java Programs >> Add Two Numbers

 In this post, we will learn how to add two numbers in Java. Here we will write a Java program to add two numbers using Scanner(user input) and without the scanner.

Add Two Number in Java

First, we will add two numbers without using a Scanner or without taking any user inputs.

Java Program: 
public class AddTwoNumbers {
    public static void main(String[] args) {
        int num1 = 10;
        int num2 = 35;
        int sum;
        sum = num1 + num2;
        System.out.println("sum of " + num1 + " and " + num2 +
                            " is: " + sum);
    }
}

Output: 
sum of 10 and 35 is: 45

Add Two Numbers using Scanner

In this Java program will take two user inputs and then print their sum.

Java Program: 
import java.util.Scanner;

public class AddTwoNumbers {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter first number");
        int num1 = sc.nextInt();
        System.out.println("Enter second number");
        int num2 = sc.nextInt();
        int sum = num1 + num2;
        System.out.println("sum of " + num1 + " and " + num2 +
                            " is: " + sum);
    }
}

Output: 
Enter first number
22
Enter second number
89
sum of 22 and 89 is: 111
