💬 Client-Server Chat Application

A real-time chat application built using Java Socket Programming, Multithreading, and Java Swing. The project demonstrates client-server communication, concurrent connection handling, and interactive desktop-based messaging.

---

📖 About The Project

The Client-Server Chat Application is a desktop-based messaging system developed using Java Socket Programming, Java Swing, and Multithreading.

The application establishes communication between a server and client over TCP sockets, allowing users to exchange messages in real time. The server is responsible for managing incoming client connections, while the client provides an intuitive graphical interface for sending and receiving messages.

This project demonstrates the practical implementation of networking concepts, concurrent programming, event-driven GUI development, and object-oriented programming using Java.
