Большое количество сплошного кода в одном методе очень затрудняет читаемость кода. Лучше разбивать код на логические блоки и выносить в отдельные методы или классы. Например, можно вынести весь код в циклах while(true), который отвечает за ввод количества гостей/ввод продуктов, в отдельные методы inputGuests, inputProducts. |
