# Chat Application

## Overview

This repository contains two chat applications: `ChatAppTCP` and `ChatAppUDP`. Both applications allow multiple users to communicate in real-time via a graphical user interface (GUI). 

- **ChatAppTCP**: Uses the TCP protocol to ensure reliable communication.

- **ChatAppUDP**: Uses the UDP protocol for faster, but less reliable communication.

## Features

- User registration and login.

- Real-time messaging.

- Display of connected users.

- User-friendly GUI.

- Server-side logging and control panel for the TCP application.

## Requirements

- Java SE Development Kit (JDK) 8 or higher.

- Network connection.

## Usage

### ChatAppTCP

The TCP-based chat application provides a reliable messaging service, ensuring messages are delivered in the correct order and without loss.

#### Server

1. First, run `ServerMain.java`.

2. Start the server using the "Start Server" button in the GUI.

3. Monitor connected users and server status.

4. Optionally, stop the server using the "Stop Server" button.

#### Client

1. Run `ClientMain.java`.

2. Enter your username in the prompted dialog.

3. The client connects to the server at `localhost` on port `8000`.

4. Use the GUI to send messages and see the list of connected users.

#### Directory Structure

- `Client.java`: Manages the client's connection, sending and receiving messages.

- `ClientGUI.java`: Provides the client's GUI.

- `ClientMain.java`: Entry point for the client application.

- `Server.java`: Manages client connections and broadcasts messages.

- `ServerGUI.java`: Provides the server's GUI.

- `ServerListener.java`: Handles communication with individual clients.

- `ServerMain.java`: Entry point for the server application.

- `User.java`: Represents a user and maintains a list of connected users.

### ChatAppUDP

The UDP-based chat application provides a faster messaging service, but without the guarantees of message order and delivery.

#### Client

1. Run `Main.java` file to start up the client.

2. Enter your username in the prompted dialog.

3. The client connects to the server using multicast address `234.235.236.237` on port 8000.

4. Use the GUI to send messages and see the list of connected users.

#### Directory Structure

- `GUI.java`: Provides the client's GUI.

- `Main.java`: Entry point for the client application.

- `NetworkReceiver.java`: Handles receiving messages from the server using UDP.

- `NetworkSender.java`: Handles sending messages to the server using UDP.

- `User.java`: Represents a user and maintains a list of connected users.

## Notes

- Ensure the server is running before starting the clients.

- The TCP application is configured to connect to `localhost` on port `8000`. Modify the source code if a different address or port is required. The UDP application is using multicast for external communication.

- Both TCP and UDP applications use the same `User.java` class for representing users.
