Chatting App - Java-Based Secure Multi-User Chat Application

Project Overview

"Chit Chat" is an advanced, Java-based multi-user chat application designed to deliver a secure and efficient online communication experience. Built using a client-server architecture, the application combines Java Swing for its graphical user interface, JDBC for robust database interactions, and socket programming for real-time communication. This project emphasizes security, performance, and user experience, making it ideal for educational purposes and small to medium-sized enterprises looking for reliable communication tools.

Features

• Real-Time Communication: Multi-threaded server that handles multiple users simultaneously for dynamic and instantaneous messaging.
• Security: Implements MD5 hashing for password encryption to secure user data.
• Database Efficiency: Utilizes JDBC with a CommonDAO interface for optimized database interactions and reduced memory usage.
• SQL Injection Prevention: Employs PreparedStatement in the UserDAO class to enhance security.
• User-Friendly GUI: Developed with Java Swing, providing an interactive and intuitive interface.
• Design Patterns: Uses Singleton for effective configuration management and scalability.
• Robust Logging: Detailed logging mechanisms to help track activities and debug issues.
• Dynamic Configuration: Supports external configuration files for easy adaptability to different environments without recompilation.
