The sort order is always ascending, where the Comparator defines which items are larger than others.

From the documentation for Collections.sort(List list, Comparator c):

Sorts the specified list according to the order induced by the specified comparator.

From the documentation for Comparator.compare(T,T):

Compares its two arguments for order. Returns a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.
