Hello Jeanne and Scott. I believe that I have found an error. There is said Comparator class but should be interface

There is also a class called Comparator, which is used to specify that you want to use a different order than the object itself provides.

I couldn't find that in the errata, so you may have found a “new” error.

And,  besides, that object may not provide any ordering at all (if it does not implement Comparable).
