And then you’ll see that there is ListIterator, in which you can also go
back, and thus to the first element.
Jakarta Commons Collections offers a lot of interesting cl*****
implementing Iterator, such as LoopingIterator, which might be what you
are looking for. However, it is not available with generics yet. I can
send you a generified version if you want.
