What is the difference between Iterator and ListIterator?

Iterator:

Using Iterator we can iterate only in forward direction and you cannot add elements while iterating and Here cursor always points to specific index.

Example:

 public class Example {
 
  public static void main(String[] args) {
 
    ArrayList aList = new ArrayList();
 
    aList.add("1");
    aList.add("2");
    aList.add("3");
    aList.add("4");
    aList.add("5");
   
    Iterator itr = aList.iterator();
 
     while(itr.hasNext())
      System.out.println(itr.next());
 
  }
}

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 :)
