如何排序2d链表数组

I have got a 2d list array to which I am adding characters in a loop like below. I need to be able to sort in lexiographical order each sub container of of the 2d array. Unfortunately, Collections.sort(list) does not work in this case.

我有一个2d列表数组，我在下面的循环中添加字符。我需要能够按照lexiographical顺序对2d数组的每个子容器进行排序。不幸的是，Collections.sort（list）在这种情况下不起作用。

  List<Character>[][] list = new LinkedList[n][n];


  for (int j = 0; j < n; ++j)
  {
     for (int m = 0; m < 1; m++)
     {
                // Here is the problem
        list[j][m].add(new Character('b'));

        // sort the array and continue
    }
  }

If you want to compare a list of a lists, I suggest you to use the ColumnComparator class:
