What is different between Iterator and ListIterator?

We can use Iterator to traverse Set and List collections whereas ListIterator can be used with Lists only. Iterator can traverse in forward direction only whereas ListIterator can be used to traverse in both the directions. ListIterator inherits from Iterator interface and comes with extra functionalities like adding an element, replacing an element, getting index position for previous and next elements.
