Java Chat Application

A simple client-server chat application using Java socket programming. Multiple clients can connect to the server, and messages are broadcast in real-time.

Features

• Multi-client support with separate threads for each client.
• Broadcast messaging to all clients except the sender.
• Automatic client disconnection handling.

How It Works

1. Server

• Listens for client connection requests on a specific port.
• Creates a new thread for each client connection using the ClientHandler class.

2. ClientHandler

• Manages communication between the server and each client.
• Broadcasts messages from one client to all other clients.
• Handles client disconnection and resource cleanup.

3. Client

• Sends and receives messages.
• Each client runs on its own thread, with messages broadcast to all connected clients.
• Sending messages is handled by the main thread of the client object.
• listening to messages is handled by a new separate thread.

Code Structure

• Server.java: Initializes ServerSocket, accepts connections, and manages threads.
• ClientHandler.java: Handles client communication and broadcasting messages.
• Client.java: Sends messages and listens for incoming messages.

Setup

1. Clone the repository:

   git clone https://github.com/Muhammed-Amer/GroupChat.git
   cd GroupChat/src

2. Compile the server and client:

   javac Server.java
   javac Client.java

3. Start the server:

   java Server

4. In another terminal, run the client: you can make a terminal to each client.

   java Client
