❓ 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() ).

Should I buy bitcoin?

“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.

The STAR Market, as is implied by the name, is heavily geared toward smaller innovative tech companies, in particular those engaged in strategically important fields, such as biopharmaceuticals, 5G technology, semiconductors, and new energy. The STAR Market currently has 340 listed securities. The STAR Market is seen as important for China’s high-tech and emerging industries, providing a space for smaller companies to raise capital in China. This is especially significant for technology companies that may be viewed with suspicion on overseas stock exchanges.
