自定义一个List排序规则，然后对另一个List按照该规则排序

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

public static void main(String[] args) {      String[] regulation = {"诸葛亮","鲁班","貂蝉","吕布"};      final List<String> regulationOrder = Arrays.asList(regulation);      String[] ordered = {"貂蝉","诸葛亮","吕布","貂蝉","鲁班","诸葛亮","貂蝉","鲁班","诸葛亮"};      List<String> orderedList = Arrays.asList(ordered);      Collections.sort(orderedList, new Comparator<String>()      {          @Override          public int compare(String o1, String o2)          {              int io1 = regulationOrder.indexOf(o1);              int io2 = regulationOrder.indexOf(o2);              return io1 - io2;          }      });      System.out.println(orderedList);  }
