Создание новых объектов с другим классом

Question

Итак, я, наконец, закончил свое задание и тестировал его, создав объекты, используя правый клик «Новая учетная запись» и т. Д., Все это прекрасно работает, и из того, что я вижу, Суперклассы и подклассы все связаны правильно, однако моя работа протестирована с использованием тестового класса HW2, который при запуске должен создать несколько учетных записей и распечатать их данные на терминале. Однако на выходе отсутствуют загружаемые материалы по сравнению с тем, что должно быть похоже, в основном я хочу знать, почему тестовый скрипт не создает объекты правильно. Я написал много кода, но я считаю, что проблема заключается только в конструкторах.

Answer 1

Ваши методы toString не являются полными. Вы можете видеть, что набор тестов в основном создает экземпляр класса и печатает его. Учетная запись toString (и, возможно, PersonalAccount тоже) должна вернуть содержимое в правом окне, которое включает не просто имя.

Вместо return name.toString();, вы хотите что-то больше похоже на return name.toString() + "\n" + otherField.toString();
