❓ Что такое сервлеты?

Сервлеты — это Java-классы, которые обрабатывают HTTP-запросы и формируют HTTP-ответы на стороне сервера. Они работают внутри сервлет-контейнера (например, Tomcat), расширяя функциональность веб-сервера. Обычно используются для создания динамического контента, например, генерации HTML на лету или обработки форм.

Сервлет реализует интерфейс javax.servlet.Servlet (чаще через HttpServlet) и переопределяет методы вроде doGet(), doPost(). Их жизненный цикл включает три ключевых этапа: инициализация (init() ), обработка запроса (service()/doX() ), уничтожение (destroy() ).

The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
