Я не могу найти решение для своего кода, я получаю «ожидаемый класс, интерфейс или перечисление» при попытке скомпилировать мой код.
Я пытался выяснить, как решить проблемуно я, к сожалению, не смог этого сделать, так как кажется, что у меня ничего не работает ... также, если есть какие-то ошибки, которые могут привести к тому, что он не будет работать после исправления этой части, пожалуйста, дайте мне знать, что я могу изменить!
