Все, кажется, работает нормально, за исключением, когда я печатаю с использовать спасатель, после выбора 1, он пропустит этот вопрос, как я хочу, чтобы он, но он также дает мне индекс из связанной ошибки, и он говорит, что это на линии 150, я так запутался в этом, все остальные работают нормально.
Пожалуйста, помогите мне, спасибо
Можете ли вы опубликовать stacktrace и указать место, где возникает исключение? – Marv
Вы должны указать _where_, исключение происходит. Никто не хочет просматривать старую домашнюю свадьбу на 250 строк. – August
Что такое линия 150? Очень много кода для просмотра. –
