Невозможно понять, как заставить игру остановиться, когда игрок набирает 5 очков.

Question

У меня есть игра, которая имитирует двух игроков, переворачивающих монету и угадывающих голов или хвостов. Игра должна останавливаться, когда первый игрок получает 5 очков. Я пробовал какое-то заявление, но он не останавливается до тех пор, пока оба не превысят 5. Новые для программирования и могут использовать свежий набор глаз с большим количеством знаний, чем я. Спасибо всем за любую помощь. (Посмотреть на код, начиная с // играть в игру.)

Answer 1

Изменить

while (player1.getPoints() <= maxPoints || player2.getPoints() <= maxPoints) 

в

while (player1.getPoints() <= maxPoints && player2.getPoints() <= maxPoints) 

Answer 2

в то время как цикл:

while (player1.getPoints() <= maxPoints || player2.getPoints() <= maxPoints) 

следует вместо be:

while (player1.getPoints() <= maxPoints && player2.getPoints() <= maxPoints) 

Причина в том, что || означает, что цикл while не будет выходить, если только BOTH не больше 5, а не один. Изменение этого параметра на && означает, что цикл выполняется только в том случае, если оба значения истинны.
