❓ Что такое сервлет?

Сервлет — это Java-класс, который обрабатывает HTTP-запросы и формирует HTTP-ответы в веб-приложениях. Он работает на стороне сервера в контейнере сервлетов (например, Tomcat), реализуя интерфейс javax.servlet.Servlet (чаще — через абстрактный класс HttpServlet).

Основная задача сервлета — выступать в роли контроллера в архитектуре MVC: принимать запросы от клиента, обрабатывать данные (либо делегировать бизнес-логике), и передавать результат обратно клиенту (обычно через HTML или JSON).
