Вопрос с собеседования

Чем @Component, @Service и @Repository отличаются друг от друга?

Ответ: Все три аннотации создают Spring-бин, но:
▶️ @Component – универсальная аннотация для любых бинов
▶️ @Service – указывает, что класс содержит бизнес-логику
▶️ @Repository – используется для DAO-слоя, добавляет обработку SQL-исключений

What is Secret Chats of Telegram

Secret Chats are one of the service’s additional security features; it allows messages to be sent with client-to-client encryption. This setup means that, unlike regular messages, these secret messages can only be accessed from the device’s that initiated and accepted the chat. Additionally, Telegram notes that secret chats leave no trace on the company’s services and offer a self-destruct timer.

That strategy is the acquisition of a value-priced company by a growth company. Using the growth company's higher-priced stock for the acquisition can produce outsized revenue and earnings growth. Even better is the use of cash, particularly in a growth period when financial aggressiveness is accepted and even positively viewed.he key public rationale behind this strategy is synergy - the 1+1=3 view. In many cases, synergy does occur and is valuable. However, in other cases, particularly as the strategy gains popularity, it doesn't. Joining two different organizations, workforces and cultures is a challenge. Simply putting two separate organizations together necessarily creates disruptions and conflicts that can undermine both operations.
