Answer 1

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.

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.)
