❓ Чем отличается агрегация от композиции?

Композиция и агрегация — это разновидности отношений «часть-целое» в объектно-ориентированном программировании.

🔹 Композиция — жесткая связь. Если уничтожается целый объект, то уничтожаются и его части.
Пример: Двигатель — это часть автомобиля. Если удалить машину, двигатель тоже исчезнет.

Пример: Университет и студенты. Университет может закрыться, но студенты продолжат существовать.

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.”
