Вопрос с собеседования

Чем отличается класс от интерфейса в Java?

Ответ: Класс может содержать состояние (поля), реализацию методов и конструкторы. Интерфейс описывает только поведение — методы без реализации (за исключением default/static). Класс можно расширить один, а интерфейсов реализовать много.

Telegram Gives Up On Crypto Blockchain Project

Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”
