You are tasked with developing a simple online chat application using Java. The application should allow multiple users to connect to a central server, send messages, and receive messages from other users.

Requirements:

$1.$ Server Implementation:

a$.$ Create a server class,$$ChatServer$,$ using socket programming to manage connections from multiple clients.

b$.$ The server should be able to handle incoming connections, assign a unique user ID to each connected client, and maintain a list of connected users.

$2.$ Client Implementation:

a$.$ Implement a client class,$$ChatClient$,$ that connects to the server using sockets.

b$.$ Each client should be able to send messages to the server, which will broadcast the messages to all connected clients.

c$.$ Clients should also be able to receive messages from other users.

$3.$ User Interface:

a$.$ Include a simple text$-$based for the client to facilitate message input and display.

Guidelines

$$ Submit well$-$commented Java source code.

$$ Screenshot of the Text base User interface.

$$ Include a README file explaining how to run your chat application and providing details about your implementation.

Grading Criteria

$$ Server Implementation: Implementation of socket programming concepts, user management, connection handling.

$$ Client Implementation: Implementation of socket connection, messaging sending, Message broadcasting

$$ User Interface: Creation of a user interface which is usable.

$$ Logic and Computation$$

$$ Program Flow and Structure$$

$$ Output.

$$ Code style and readability.
