The Java.util.LinkedList.listIterator() method is employed to return a list-iterator containing an equivalent elements as that of the LinkedList in proper and same sequence ranging from a selected position or index which is passed as a parameter to the present method.

In Java, LinkedList is a data structure that represents a sequence of elements, where each element is linked to its next element using a reference. The LinkedList class in Java provides various methods to traverse, add, remove and manipulate the elements in the list. One such method is the listIterator() method, which returns a ListIterator object for the LinkedList.

The listIterator() method returns a ListIterator that allows you to traverse the LinkedList in both directions, forward and backward. The ListIterator object provides several methods to access, modify and remove the elements in the list. You can use the hasNext() method to check if the list has more elements to traverse in the forward direction, and hasPrevious() method to check if the list has more elements to traverse in the backward direction.

You can use the next() method to get the next element in the forward direction, and previous() method to get the previous element in the backward direction. The ListIterator also provides methods to add and remove elements at any position in the list, using add() and remove() methods respectively.

Overall, the listIterator() method provides a powerful way to traverse, modify and manipulate the elements in a LinkedList in both forward and backward directions.
