С моим кодом у меня возникают проблемы с добавлением цикла в конец, чтобы код начинался заново

Question

С моим кодом мне нужен цикл, который запускает код заново.Они говорят «встроить вашу программу в цикл с последним оператором / условием выхода в виде строки, равной no», но я до сих пор не понимаю, где ее поместить и какой цикл использовать.

Answer 1

Хотя ответ, заданный Sand выше, является полностью правильным, учитывая количество используемых вами условий, которые не являются прямыми булевыми значениями, в конечном итоге будет быстрее и эффективнее использовать случай переключения, а также сохранятьвам нужно немного печатать на современных компьютерах, это не должно быть проблемой, но тем не менее

небольшое примечание на тот случай, если вы хорошо знакомы с переключателями, вкратце, они похожи на длинныецепочка условных выражений, но как только одна задача выполнена, она не продолжает искать ее по всем значениям в виде последовательности операторов if, имеющих значение, как только что-то работает, она завершается вместо проверки каждого условия и для случаев, в которых нетBoolean считается быстрее читать дальше здесь

Answer 2

Вы можете использовать цикл while, как показано ниже, и когда пользователь вводит 2, прервите его

import java.util.*;

            int a = kbReader.nextInt();
            if (a == 1) {

            }
            if (a == 2) {
