Я довольно новичок в java, и мы действительно не рассмотрели методы, но это было необходимо для проекта. Я пытаюсь разместить целые две петли do-while в методе, который я могу вызвать в пределах public void run(). Может ли кто-нибудь помочь мне узнать, как я могу это сделать? Я пытаюсь поместить этот вложенный цикл с внутренними и внешними do-while петель внутри своего собственного метода, возможно, в своем классе такжеJava do-while цикл внутри метода в своем собственном классе
Вот полный код:
раздел, где цикл начинается в do Я пытаюсь поместить его в своем собственном методе и как я могу это сделать?

@aioobe это именно то, что я пытаюсь выполнить, но не знаю, как я мог бы сделать метод для цикла. Он не распознает код, когда я просто создаю для него свой собственный класс. – Dmitriy
