❓ Что такое наследование в Java?

Наследование — это механизм ООП, позволяющий создавать новый класс на основе уже существующего. Новый класс (подкласс) получает все свойства и методы родительского класса (суперкласса), что обеспечивает повторное использование кода и упрощает поддержку.

Наследование реализуется с помощью ключевого слова extends. Подкласс может расширять или переопределять поведение суперкласса, а также добавлять новые поля и методы. Важно помнить, что в Java класс может наследоваться только от одного суперкласса.

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.

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.
