OOP 3: SortNames

I have a question about the SortNames assignment. I have it all working except for the sort by last name, as I am finding out this is the hardest part of the project.
When you say don't modify the Strings in the ArrayList, does that mean I can't make a copy of the ArrayList and modify those Strings. Basically I was thinking of taking a copy of the list, chopping off the first name, sorting it, and then comparing it back to the old array to print it in order. Is there an easier way or a class or method I am missing?
Thanks,
Bill

Actually I found a slightly easier way, but I am still creating my own methods and not using something from the API.

Rather than create a new list, the purpose of the assignment is for you to use the existing list and force a new way to do the sorting.� Take a look at an alternative way to call Collections.sort()

Thanks Marilyn. I see it now. I have never used that method so it was nice to see how it works.
