User Registration and Login Web Application

WebApplication.mp4

This is a Java-based web application that allows users to register, log in, and view their details through a clean and intuitive interface. It uses Java Servlets, JSP, JDBC, and MySQL for backend operations, with HTML, CSS, and Bootstrap for frontend design. This project demonstrates a practical, full-stack implementation of user authentication and session management.
