A Java Servlet-based web application that dynamically generates random quizzes from a PostgreSQL database. The project is deployed on an Apache Tomcat server, demonstrating the integration of core Java EE components, JDBC for database operations, and a simple yet functional frontend to provide an interactive quiz experience.
This application allows users to take a randomly generated quiz consisting of multiple-choice questions. The backend logic is written using Java Servlets, which interact with a PostgreSQL database using JDBC to fetch and render questions dynamically. It's hosted on an Apache Tomcat server and is designed to be lightweight, fast, and modular for easy extension.
