Question

我的节目适合两个玩家。每个玩家每次掷骰子三次，在那里他们可以保持每次滚动的数字。如果他们从第一次滚动中保留一个号码，他们可以继续滚动两次，直到他们选择保留该号码。两个骰子加在一起，总和最高的玩家获胜。我有一个玩家类（负责保持骰子值），掷骰子和确定总和的pairOfdice类以及主游戏。当我运行程序时，我从diceGame类中收到这些错误。我想知道这些错误意味着什么。我的代码尚未完成。

getHoldA（）不能应用于（int）
getHoldB（）无法应用于（int）

Answer 1

您正在尝试使用getter（不带参数）来设置值。自然，Java不知道如何处理这个问题。

  player.getHoldA(dice.getDiceA());

应该是

  player.setHoldA(dice.getDiceA());

Answer 2

您的方法getHoldA和getHoldB不接受任何参数，但您使用值player.getHoldA(dice.getDiceA());调用它们也许您打算调用setter？

Java Objects类和方法编程有问题
