Java Calculator

Overview

This is a simple console-based calculator program written in Java. It performs basic arithmetic operations: addition, subtraction, multiplication, and division. The program takes user input for numbers and operations, displays the result, and allows repeated calculations until the user chooses to exit.

Features

• Addition, Subtraction, Multiplication, Division
• Handles division by zero with an error message
• User-friendly console prompts
• Continuous operation until the user exits

Requirements

• Java Development Kit (JDK) installed (version 8 or above recommended)
• Command-line interface to compile and run the program

How to Compile and Run

1. Open a terminal or command prompt.
2. Navigate to the directory containing 'calculator.java'.
3. Compile the program using: javac calculator.java
4. Run the program using: java calculator
5. Follow on-screen prompts to use the calculator.

Usage Instructions

• Enter two integer numbers when prompted.
• Choose an operation by entering the corresponding number (1 to 4).
• View the result displayed.
• When asked if you want to continue, enter '1' for yes or '2' to exit.

Code Structure

The main logic is contained within a 'while(true)' loop that:

• Prompts for inputs,
• Executes the chosen operation using a 'switch' statement,
• Displays results or error messages,
• Queries the user to continue or exit.

Notes

• The program uses the Scanner class for input and properly closes it upon exit.
• Only integer inputs are supported; input validation for non-integers is not implemented.
• Feel free to fork and improve the project.
