//這裏的順序，是我自己定義的一個List<String>
String[] regulation = {"諸葛亮","魯班","貂蟬","呂布"};
final List<String> regulationOrder = Arrays.asList(regulation);
String[] ordered = {"貂蟬","諸葛亮","呂布","貂蟬","魯班","諸葛亮","貂蟬","魯班","諸葛亮"};
List<String> orderedList = Arrays.asList(ordered);
Collections.sort(orderedList, 
 
new Comparator<String>()
{
    public int compare(String o1, String o2)
    {
        int io1 = regulationOrder.indexOf(o1);
        int io2 = regulationOrder.indexOf(o2);
        return io1 - io2;
    }
});
System.out.println(orderedList);

Collections自定義List排序規則，進行自定義排序
