如何在2D数组中捕获重复的字符串值并替换它

Question

我创建了一个程序，根据用户输入的掷骰子次数掷两次骰子。每两个滚动都被存储为x和y值，并插入到二维数组中相应的位置。然而，我不能想出一个正确的方法来抓住当骰子滚动重复。

数组如下:

String [][] arr =  {
{"0,0","0,0","0,0","0,0","0,0","0,0"},
{"0,0","0,0","0,0","0,0","0,0","0,0"},
{"0,0","0,0","0,0","0,0","0,0","0,0"},
{"0,0","0,0","0,0","0,0","0,0","0,0"},
{"0,0","0,0","0,0","0,0","0,0","0,0"},
{"0,0","0,0","0,0","0,0","0,0","0,0"}
};

如果骰子输出为:"4 "4和5"4 ">

则数组将显示为:

二维阵列输出

将这些数字插入2D数组的当前代码如下:

public static String[][] updateArray(String[][] arr, int userInput) {
for (int rolls = 0; rolls < userInput; rolls++) {
int roll1 = rollDice(); // x
int roll2 = rollDice(); // y
String rolled = roll1 + "," + roll2;
System.out.println("The dice rolled: " + roll1 + " and " + roll2);
int xIndex = roll1 - 1;
int yIndex = roll2 - 1;
arr[yIndex][xIndex] = rolled; // first value is y second is x
}
return arr;
}

应该发生的是，程序应该发现有一个重复的数字，并且只滚动这两个特定的数字，以得到一个没有重复的数组。

我已经尝试了许多复杂的方法，但仍然不适合我。我相信有一个更简单的解决办法。如果您需要进一步的说明，请告诉我。
