❓ 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.
