Question

我的编程课程作业。我只有一个我无法弄清楚的问题。

我的说明如下：编写一个程序，模拟玩家掷骰子100次后获胜的频率。如果玩家掷出7或11，他们就赢了

我的问题如下：我的节目显示我赢的次数比我应该多。我只希望我的程序打印出用户赢得的消息，如果他们有七个或十一个，但是没有发生。有人可以就我可能需要做些什么给我一些建议吗？

以下是我的代码。非常感谢您的帮助。

我认为您不需要在代码中使用if条件。

if (sumOfDies == point) { System.out.println(sumOfDies + " You Won! Congratulations! You Won! Congratulations!"); return true; }

实际上你需要在你的代码中满足条件。

if (sumOfDies == 7 || sumOfDies == 11) { System.out.println(sumOfDies + " You Won! Congratulations! You Won! Congratulations! "); return true; }
 else  { System.out.println(sumOfDies + " Congratulations! You Lost! "); return false; }

这是你的功能应该如何工作：

    public static boolean craps(Random rand) {
      int firstDice = rand.nextInt(6)+1;
      int secondDice = rand.nextInt(6+1); 
      int sumOfDies = firstDice + secondDice; 
      System.out.print("[" + firstDice + "," + secondDice + "]"); 
      if (sumOfDies == 7 || sumOfDies == 11) { 
            System.out.println(sumOfDies + " You Won! Congratulations! You Won! Congratulations! ");
            return true;
      } else {
            System.out.println(sumOfDies + " Congratulations! You Lost! "); 
            return false; 
     }
}
