This repository contains a straightforward Java-based chat application using the TCP protocol, consisting of a server and a client.

The server is responsible for handling incoming client connections and facilitating communication between clients. It allows clients to send messages, change their nicknames, and gracefully quit the chat. The server is a multithreaded application, capable of handling multiple client connections simultaneously.

Follow these steps to run the server:

1. Compile the Server.java file.
2. Run the compiled Server class.

The server will start listening on port 9999 for incoming client connections.

The client is a command-line application that connects to the server, enabling users to send and receive messages in a chat room. Clients can also change their nicknames and quit the chat gracefully.

Follow these steps to run the client:

1. Compile the Client.java file.
2. Run the compiled Client class.

The client will connect to the server running on 127.0.0.1 (localhost) on port 9999 by default. You can change the server address in the Client class if needed.

• When a client connects, they will be prompted to enter a nickname.
• Clients can send messages to the chat by typing their messages and pressing Enter.
• To change their nickname, clients can use the "/nick" command followed by the desired nickname (e.g., "/nick NewNickname").
• To quit the chat, clients can use the "/quit" command.

• Multithreaded server that can handle multiple client connections simultaneously.
• Ability for clients to change their nicknames to distinguish themselves in the chat.
• Graceful handling of client disconnections.

• Clients may need to press Enter after sending a message to see new messages from other users due to buffering.

This is a basic chat application using the TCP architecture and can be further improved and extended. You can contribute to this project by:

• Enhancing its features.
• Improving its user interface.
• Fixing any known issues.

We welcome your contributions to make this chat room more robust and user-friendly. Please check the issues section for any existing tasks or propose your enhancements.
