Java. Adapter Pattern in Game Server
Адаптер - это шаблон структурного проектирования, который позволяет объектам с несовместимыми интерфейсами взаимодействовать друг с другом.
Так же известен как “Обертка”.
Проблема
Чтобы продемонстрировать этот шаблон, я буду использовать упрощенный пример игровой механики, в которой есть интерфейс IEnemy, но один из врагов отличается от других и не имеет реализации метода атаки. Вместо этого этот конкретный враг (SpecialEnemy) накладывает заклинания .

Что должен знать Java Software Engineer
Есть много разных понятий для человека, который занимается программированием: кодер, разработчик, программист и т.д. Мне же больше по душе такое понятие, как инженер-программист или software engineer, т.к. данное понятие охватывает наибольшее количество тем и направлений, необходимых для разработки. Это лично моё виденье.
Так чем же принципиально software engineer отличается от остальных регалий? Ответ достаточно прост и очевиден - набором знаний о технологиях и большим кругозором в сфере, которой он себя посветил. Кроме того, сталкиваясь с какой-либо проблемой или задачей, он уже понимает какой подход нужен для её решения, или знает, что надо "подтянуть", чтобы быть компетентным в данном вопросе.
Т.к. на данный момент мой основной язык программирования Java, то и рассматривать данный вопрос я буду со стороны Java. Однако общая концепция хорошо ложится на другие языки с небольшой корректировкой "под себя".
Цель статьи привести - познакомить читателя с предлагаемым мною набором знаний. Ниже я привожу набор направлений и технологий, которыми должен обладать с теоретической и практической точки зрения software engineer.
