📐 Geometry Drawer 📏

An interactive geometric shape drawing and calculation application developed with Java Swing.

Geometry Drawer is a desktop application that allows users to draw basic geometric shapes like circles, squares, and triangles, and instantly calculate their area and perimeter. With its user-friendly graphical interface, it's an ideal tool for visualizing geometric concepts and performing quick calculations.

✨ Features

• Interactive Drawing: Users can draw shapes directly on the canvas using the mouse.
• Instant Calculations: The area and perimeter of each drawn shape are automatically calculated and displayed.
• Variety of Shapes: Ability to draw circles, squares, and triangles.
• User-Friendly Interface: An intuitive and clean interface designed with Java Swing.

🚀 Setup and Running

Setting up and running this project on your local machine is quite straightforward.

Prerequisites

• Java Development Kit (JDK) 8 or newer: Required to compile and run the project.

Steps

1. Clone the Repository: First, download the project's source code to your computer. Open your terminal (Mac/Linux) or Command Prompt/PowerShell (Windows) and run the following command:

   git clone https://github.com/ItsMerad/Geometry-Drawer.git

2. Navigate to the Project Folder: Change your current directory to the main project folder you just cloned:

   cd Geometry-Drawer

3. Compile the Source Code: You need to compile the .java source files to create .class files. We'll compile all Java files located in the src/Geometry_Drawer/ directory:

   javac -d out src/Geometry_Drawer/*.java

4. Run the Application: After compilation is complete, you can run the application via its main class. The main class for this application is likely Geometry_Drawer.GeometryDrawer.

   java -cp out Geometry_Drawer.GeometryDrawer

   • -cp out: Specifies that compiled .class files are in the out directory.
   • Geometry_Drawer.GeometryDrawer: The fully qualified name of your main class (including its package).

🛠️ Development Environment

This project was primarily developed using the following tools:

• Java
• Java Swing (for the graphical user interface)
• Git (for version control)
• Visual Studio Code (as the primary development environment)

📚 Learnings

Developing the Geometry Drawer application was an insightful journey that solidified my understanding of several key programming concepts and best practices:

• Mastering Java Swing: Gained practical experience in designing and implementing interactive graphical user interfaces (GUIs) using Swing components, including event handling for user interactions like drawing on a canvas.
• Object-Oriented Design (OOD) in Practice: Applied OOD principles to model geometric shapes (Circle, Square, Triangle) as distinct objects, inheriting from a common Shape interface or abstract class to manage their properties and behaviors (e.g., calculating area and perimeter).
• Understanding Compilation and Execution: Reinforce my knowledge of the Java compilation process (javac) and how to execute Java applications from the command line, including managing class paths.
• Version Control Workflow: Further practiced essential Git commands such as add, commit, and push, deepening my understanding of version control for tracking project evolution.
