推荐答案

到目前为止，最好的方法是重新考虑设计并将所有三个相关数据放入为此目的而设计的类的实例中，然后对一个ArrayList进行排序.

By far the best way to do this would be to rethink the design and put all three pieces of related data into instances of class designed for this purpose, then just sort the one ArrayList.

其他任何方法都可能涉及设置一些Map来保存String之间的关系，然后在对第一个列表进行排序后(困难的混乱)手动移动列表，或者编写自己的排序算法从而将后两个列表与第一个一起移动(可能更容易，但更糟的是混乱).

Any other method would involve either setting up some Maps to hold the relationships between the Strings, and then manually moving the lists around after sorting the first one (a difficult mess) or writing your own sorting algorithm which moved the second two lists in tandem with the first (probably easier, but an even worse mess.)
