Program to Add Two Integers in java

Java is a popular programming language that is widely used in the development of web applications, mobile applications, and other software applications. It is an object-oriented language that offers a wide range of features and functionalities. In this blog, we will discuss how to write a Java program to add two integers.

Adding two integers is a basic arithmetic operation that is used in many programming applications. To write a Java program to add two integers, you need to follow these steps:

Step 1: Declare the two integer variables that you want to add. You can name these variables whatever you want, but it is a good practice to give them meaningful names.

Step 2: Initialize the two integer variables with the values that you want to add. You can use user input or hardcode the values in the program.

Step 3: Add the two integers using the "+" operator and store the result in a variable.

Step 4: Print the result on the console using the "System.out.println()" method.

Here is the Java program to add two integers:

java

Copy code

import java.util.Scanner;

public class AddTwoIntegers {

   public static void main(String[] args) {     

      int num1, num2, sum;

      Scanner sc = new Scanner(System.in);    

      System.out.println("Enter the first integer:");

      num1 = sc.nextInt();     

      System.out.println("Enter the second integer:");

      num2 = sc.nextInt();   

      sum = num1 + num2;

      System.out.println("The sum of " + num1 + " and " + num2 + " is " + sum + ".");

   }

}

Let's take a closer look at the program. First, we import the Scanner class to read user input. Then, we declare three integer variables: num1, num2, and sum. We also create a Scanner object called sc to read user input from the console.

Next, we prompt the user to enter the first integer and read the input using the "nextInt()" method of the Scanner class. Similarly, we prompt the user to enter the second integer and read the input.

After that, we add the two integers using the "+" operator and store the result in the sum variable.

Finally, we print the result on the console using the "System.out.println()" method. We concatenate the variables using the "+" operator to form the output message.

To run this program, you can save it as "AddTwoIntegers.java" and compile it using the command "javac AddTwoIntegers.java". Then, you can run it using the command "java AddTwoIntegers".

In conclusion, writing a Java program to add two integers is a simple and straightforward task. By following the above steps, you can easily add two integers and print the result on the console.
