Answers
Iterator : Iterator Can Only get Data From forward Direction .

ListIterator : An iterator for lists that allows one to traverse the list in either direction.modify the list during iteration, and obtain the iterator’s current position in the list.

A ListIterator has no current element. its cursor position always lies between the element that would be returned by a call to previous() and the element that would be returned by a call to next(). In a list of length n, there are n+1 valid index values, from 0 to n, inclusive.   Your Comment
