队列不循环，并提前终止？

Question

我正在尝试创建一个增强的猪游戏，用户可以在其中滚动用户输入的骰子数量。如果掷出的所有骰子都是一，那么您将失去您的银行积分，如果其中之一是一，您将没有积分，您的银行是安全的。否则，您可以将滚动的积分存入银行。我正在尝试遍历队列，以便每个玩家轮到他们，但它只是循环队列中的同一个人，询问玩家想要掷多少个骰子，然后得到结果并终止。我在这里做错了什么？

这也是当前的控制台输出：

您的循环控制遍历队列中的每个玩家。

for (Player e : myQueue) {

但在整个循环体中，您只引用队列中的第一个玩家，myQueue.peek()。例如：

System.out.println("How many dice would you like to roll " 
   + myQueue.peek().getPlayerName() + " ?");

peek() 方法返回队列中的第一个玩家，但您试图影响玩家e。您可以通过在整个循环体中使用e 而不是myQueue.peek() 来解决此问题。
