Well, that's true. But what can possibly be unclear about that? Can't be done, sounds pretty clear to me. What kinds of links were you looking for to expand on that? And what kind of sample code could possibly be written for something which can't be done?
Well there is no forward or backward traversal for the enhanced for-loop. An enhanced for loop uses an Iterator to traversal through a data-source. It doesn't matter if the Iterator goes through the data-source forward, backward or criss cross.

Please correct my English.
The object returned by Lists.reverse() is a view of the underlying list. If you look at how it implements iterator(), you should find that it returns an Iterator that is actually using a ListIterator and is using it in reverse.
