Concepts Used

The HTML Chat Application utilizes the following programming concepts:

Object-Oriented Programming (OOP): The application is designed using OOP principles, with classes and objects representing various components.
Java Swing Components: The graphical user interface is constructed using various Swing components like JFrame, JPanel, JTextField, JButton, and more.
Multi-threading: The application implements multi-threading to handle both server-client connections and GUI updates simultaneously, ensuring smooth performance during real-time messaging.
Client-Server Architecture: The application follows a client-server model to facilitate communication between multiple users.
