Chat Java Application

Overview

The Chat Java Application is a robust and scalable chat application developed using Java. This application allows multiple users to engage in real-time chat sessions. It is designed with a focus on simplicity and efficiency, providing essential chat functionalities through a clean and intuitive interface.

Note: This project was completed in 2019 when I was still an amateur developer and unawared about GitHub at that moment

Project Goals

• Real-Time Communication: Enable real-time messaging between multiple users.
• Scalability: Ensure the application can handle multiple concurrent users seamlessly.
• Security: Implement secure communication protocols to protect user data.
• User-Friendly Interface: Provide an intuitive and easy-to-use interface for users.
• Listening to Music: Allow users to listen to music while chatting.

Key Features

• User Authentication: Secure login and registration system for users.
• Real-Time Messaging: Send and receive messages instantly.
• Group Chats: Support for creating and managing group chat sessions.
• Private Messaging: Option for users to have private conversations.
• File Sharing: Allow users to share files within chat sessions.
• Notifications: Real-time notifications for new messages and user activities.
• Music Integration: Enable users to listen to music within the chat application.

🛠 Technologies Used

Backend

• Java: The core programming language used for developing the application.
• Socket Programming: For enabling real-time communication between the server and clients.
• Multithreading: To handle multiple client connections concurrently.
• MySQL: For storing user data and chat history.

Frontend

• Java FX: For building the graphical user interface.

Project Structure

• src/: Contains the source code of the application.
  • client/: Client-side application code.
  • server/: Server-side application code.
• assets/: Contains any images or static files used in the application.
• README.md: The main documentation file for the project.

Project Achievements
