❓ Что такое Reflection?

Reflection — это механизм, позволяющий исследовать и модифицировать поведение классов, методов, полей и конструкторов во время выполнения. Используется через API из пакета java.lang.reflect.

Позволяет:

— Узнавать структуру классов во время выполнения (Class<?>, Method, Field, Constructor);
— Вызывать методы, читать/записывать поля, даже если они private;
— Создавать экземпляры классов без new.

NEWS: Telegram supports Facetime video calls NOW!

The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.

How Does Bitcoin Mining Work?

Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. It’s a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. “This is how new coins are created” and new transactions are added to the blockchain, says Okoro.
