修改和改进java代码

Question

到目前为止，我编写的代码如下所示，但是我对它有一些问题: 1)它多次运行程序，2)数字似乎不是很随机，它似乎从相同的数字中挑选出相同的数字，我需要值1显示为Ace，值11显示为Jack，值12显示在Queen，13显示为King

我已经看过我的代码好几次了，我不知道它为什么要做第1点，我不知道是我做的，还是第2点的问题，我知道我需要一个if状态来做第3，但不太确定把它放在哪里。

这个程序的思想是让玩家在电脑上逐行绘制7张卡片(不需要包括套餐)，然后输出每张卡，其中1张为ace，11张为jack，12张为皇后，13张为king。

非常感谢你的帮助

您可以创建一个cardPlayers和cardComputers数组。例如，尝试下面的方法

 int numPlayers = 14;
 int [] cardPlayer = new int[numPlayers];
 int [] cardComputer = new int[numPlayers];

 for (int i = 0; i < numPlayers; i++) {         
            System.out.println("Player Card " + i + ": " + cardPlayer[i]);
            cardComputer[i] = rn.nextInt(7) + 1;
            System.out.println("Computer Card " + "i" + cardComputer[i]);
            System.out.println("");
}

这将提高代码的可读性，减少代码行数。
