Examples of java.util.ListIterator.nextIndex()

java.util.ListIterator.nextIndex()
Returns the index of the element that would be returned by a subsequent call to next. (Returns list size if the list iterator is at the end of the list.) @return the index of the element that would be returned by a subsequentcall to next, or list size if list iterator is at end of list.
