Java collection: iterators (Iterator, iterable)

! =expectedmodcount)Throw Newconcurrentmodificationexception (); } }The idea for the remove operation is broadly consistent except that Lastret is replaced with a list node lastreturned, which is also set to null after each remove. The get element is not obtained directly through get (i), as in the parent version. The iterator saves two adjacent node pointers lastreturned and next. When the element is removed (lastreturned=null), it can still be moved in the linked list because the next point
