ListIterator allows the programmer 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().
Example:
public class sample {
public static void main(String[] args) {
//create an object of ArrayList
ArrayList aList = new ArrayList();
//Add elements to ArrayList object
aList.add("1");
aList.add("2");
aList.add("3");
aList.add("4");
aList.add("5");
//Get an object of ListIterator using listIterator() method
ListIterator listIterator = aList.listIterator();
System.out.println(" forward direction using ListIterator");
while(listIterator.hasNext())
System.out.println(listIterator.next());
System.out.println("reverse direction using ListIterator");
while(listIterator.hasPrevious())
System.out.println(listIterator.previous());
}
}
try the above code and get back to me :)

Hi Mallik… Nice Explanation………….
