JAVA：骰子游戲，確保打印的是正確的

Question

我有我的編程課程的作業。我只有一個我無法弄清楚的問題。

我的指示如下：編寫一個程序，模擬玩家擲骰子100次後贏得的頻率。如果玩家擲出一個7或11，他們贏了

我的問題如下：我的程序顯示我比我應該贏得更多的時間。我只希望我的程序能夠打印出用戶贏得的消息，如果他們有七到十一個，但沒有發生。任何人都可以就我可能需要做的事情給我一些建議嗎？

以下是我的代碼。非常感謝您的幫助。

我覺得你不需要下面的條件，如果你的代碼。

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

事實上，所有你需要在你的代碼是以下條件。

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; } 

這裏是你的功能應該是如何工作的：

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; 
    } 
}
