Simple Chat Application

This is a simple chat application built using Java. It consists of a client and a server that allow multiple users to communicate in real-time. The server handles incoming connections and broadcasts messages to all connected clients, while the client provides a user-friendly interface for sending and receiving messages.

Features

• Real-time messaging: Send and receive messages instantly.

• Multiple clients: The server supports multiple clients simultaneously.

• Simple GUI: The client has an easy-to-use graphical interface.

• Java NIO: Uses Java's Non-blocking I/O (NIO) for efficient communication.

Project Structure

• SimpleChatClient.java: The client-side application. It connects to the server and provides a GUI for sending and receiving messages.

• SimpleChatServer.java: The server-side application. It accepts client connections and broadcasts messages to all connected clients.
