Calcy - Personal Calculator

Calcy is a simple and intuitive calculator application built using Java. This project showcases the implementation of a basic calculator with a graphical user interface (GUI) that allows users to perform arithmetic operations such as addition, subtraction, multiplication, and division.

Features ✨

• Simple GUI: Easy-to-use interface with buttons for digits and arithmetic operations.
• Basic Arithmetic Operations: Supports addition, subtraction, multiplication, and division.
• Clear Function: Ability to clear the input field.
• Keyboard Input Support: Allows users to use the keyboard for input and operations.

Prerequisites 📋

• Java Development Kit (JDK) installed
• A Java-compatible IDE (e.g., IntelliJ IDEA, Eclipse) or a simple text editor
• Basic understanding of Java programming

Installation and Setup 🚀

Steps 🛠️

1. Clone the Repository:

   git clone https://github.com/Mustafabharmal/Calculator-Java.git
   cd Calculator-Java

2. Compile the Java Files: Open a terminal in the project directory and run the following command to compile the Java files:

   javac CalcView.java

3. Run the Application: After successful compilation, run the application using:

   java CalcView

Project Structure 📁

• CalcController.java: Handles the business logic and user interactions.
• CalcView.java: Defines the GUI layout and initializes the components.

Usage Instructions 📝

Graphical User Interface 🖥️

1. Start the Calculator:

   • Run the CalcView class to launch the calculator GUI.

2. Perform Calculations:

   • Click on the digit buttons to enter numbers.
   • Use the arithmetic operation buttons (+, -, x, /) to perform calculations.
   • Press the = button to display the result.
   • Use the CLS button to clear the input field.

3. Keyboard Input:

   • You can also use the keyboard to input numbers and operations.
   • Press Enter to display the result.

Code Overview 🔍

CalcController.java

The CalcController class implements ActionListener and KeyListener interfaces to handle button clicks and keyboard inputs. It performs the arithmetic operations and updates the display accordingly.

CalcView.java

The CalcView class extends Frame and sets up the GUI components, including buttons and text fields. It initializes the controller and sets up the layout and event listeners.

Conclusion 🎉

Calcy provides a simple and interactive way to perform basic arithmetic operations using a graphical calculator interface. It demonstrates the use of Java for creating GUI applications and handling user interactions through event listeners.

Happy Calculating! 💻🚀
