About this project
This project is a classic Java networking exercise: a multi-threaded chat server built with java.net. ServerSocket accepts connections from multiple clients, each handled on its own thread, and broadcasts messages to all connected clients.
The client application (Swing-based) connects to the server over a socket, sends the user's messages, and listens on a background thread for incoming broadcast messages, updating the chat window in real time using SwingUtilities.invokeLater.
The project also supports private messaging (via a simple \"/msg username message\" command parsed on the server) and a list of currently online users, making it a solid demonstration of Java's core networking and concurrency APIs.
Detailed Project Description
Java Chat Application (Socket Programming) enables real-time message exchange between users with delivery status, using a persistent connection instead of page refreshes.
How It Works
1. A client connects to the server (or peer) and authenticates.
2. Messages are sent over a persistent channel (sockets, Bluetooth or a realtime database).
3. The server/peer relays each message to the recipient and stores history.
4. Presence, typing and delivery indicators keep the conversation live.
Technology Roles
- Java
- Sockets
- Multithreading
- Swing
Implementation Steps
1. Define requirements and draw the ER / class diagram and screen flow.
2. Set up the environment (JDK, Swing) and create the project skeleton.
3. Design the database schema / data model and seed it with sample data.
4. Implement the core modules with validation and role-based access where needed.
5. Build the user interface and connect it to the backend / data layer.
6. Test each module (unit + manual), fix edge cases and secure inputs (SQL injection, XSS, auth).
7. Prepare documentation, screenshots and a demo build.
Key Features
- Real-time delivery
- Chat history
- Presence indicators
- Group or one-to-one chat
Expected Output
On completion the student will have two or more users exchanging messages instantly.
Deliverables
- Complete source code with comments
- Database schema / data model and screen flow
- Project report with screenshots and results
- Demonstration-ready build

Delivery & Payment
Delivery takes a minimum of two weeks from the date your inquiry is confirmed.
Payment is in two parts:
• 50% advance to start the project
• Remaining 50% before delivery
Note:
• Documentation and PPT are not included by default
• If you need documentation/PPT, it can be arranged for extra time and cost
We'll confirm the exact timeline and cost with you after reviewing your requirements.
