数组排序多维数组以匹配第二个数组

Question

我有一个包含学生姓名的单一贬义数组和一个包含学生分数的二维数组，我可以很好地对名称进行排序，但我无法让分数匹配（因为它们必须保持相同的顺序）。这是我尝试的代码：

static String[] studentNamesArray = new String[10];
static int[][] studentMarksArray = new int[10][3];

  static void sortAlphabetical() { 
    String tempName;
    int intSwap;
    boolean flag = false;
    while (flag==false) {
      flag = true;
      for (int i = 0; i < 9; i++) {
        if (studentNamesArray[i].compareTo(studentNamesArray[i + 1])>0) {
          tempName = studentNamesArray[i];
          studentNamesArray[i] = studentNamesArray[i + 1];
          studentNamesArray[i + 1] = tempName;

          for(int y=0;y<2;y++){
          intSwap = studentMarksArray[i][0];
          studentMarksArray[i][y] = studentMarksArray[i+1][y+1];
          studentMarksArray[i+1][y+1] = intSwap;
          }
          flag = false;
        }
      }
    }
  }

您只需要像为名称所做的那样交换标记数组：

static void sortAlphabetical() { 
        String tempName;
        int [] intSwap; //<-- note I changed this as an int[] array
        boolean flag = false;
        while (flag==false) {
          flag = true;
          for (int i = 0; i < studentNamesArray.length-1; i++) { //<-- note I changed this to length - 1 to avoid IndexOutOfBoundsException
            if (studentNamesArray[i].compareTo(studentNamesArray[i + 1])>0) {
              tempName = studentNamesArray[i];
              studentNamesArray[i] = studentNamesArray[i + 1];
              studentNamesArray[i + 1] = tempName;

              intSwap = studentMarksArray[i];
              studentMarksArray[i] = studentMarksArray[i+1];
              studentMarksArray[i+1]= intSwap;
              flag = false;
            }
          }
        }
      }

    static String[] studentNamesArray = new String[3];
    static int[][] studentMarksArray = new int[3][3];

    public static void main (String[] args) throws java.lang.Exception {
        studentNamesArray[0] = "Mark";
        studentNamesArray[1] = "Anna";
        studentNamesArray[2] = "Arnold";

        studentMarksArray[0] = new int[]{1,2,3};
        studentMarksArray[1] = new int[]{4,5,6};
        studentMarksArray[2] = new int[]{0,0,0};

        sortAlphabetical();
        System.out.println(Arrays.toString(studentNamesArray));
        System.out.println(Arrays.deepToString(studentMarksArray));

    }

输出：

[Anna, Arnold, Mark]
[[4, 5, 6], [0, 0, 0], [1, 2, 3]]
