Servlets

Servlets are a technology used in web development to build dynamic websites. Think of them as server-side programs that run on a web server to handle requests from users, like clicking a link or submitting a form. When a user interacts with a website, the servlet processes the input, interacts with databases or other resources if needed, and generates a customized response, usually in the form of an HTML page. This allows websites to provide personalized, real-time content and functionalities without needing to refresh or reload static pages. Servlets are central to creating robust, scalable web applications in Java.
