🧮 Simple Calculator Program in Java​

In this tutorial, we’ll build a simple calculator program in Java using basic arithmetic operations. This is a great exercise for beginners who want to practice reading user input and performing simple calculations.

We’ll be using IntelliJ IDEA Community Edition — it’s free to use and easy to get started with. You can search and download it via Google. 🔍

Let’s begin by importing the required library to take input from the console:

import java.util.Scanner;

Place this import at the top of your Java class file. Then, we’ll start writing the program inside the main method.

Here is the full code:

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
       
        Scanner s = new Scanner(System.in);
       
        System.out.print("Enter the first number: ");
        int firstNumber = s.nextInt();
       
        System.out.print("Enter the second number: ");
        int secondNumber = s.nextInt();
       
        System.out.println("Sum: " + (firstNumber + secondNumber));
        System.out.println("Difference: " + (firstNumber - secondNumber));
        System.out.println("Product: " + (firstNumber * secondNumber));
        System.out.println("Quotient: " + (firstNumber / secondNumber));
       
        System.out.println("Calculation complete!");
    }
}

✅ What This Program Does:​

• Takes two integers from the user.
• Performs addition, subtraction, multiplication, and division.
• Displays the result of each operation.

This program is a great way to practice console input, working with variables, and using basic operators in Java.

Happy coding! ☕
