What does the method listIterator(n) do in java?

The listIterator(int index) method of the java.util.LinkedList class returns a list-iterator of the elements in this list (in proper sequence), starting at the specified position in the list.

Example

import java.util.*;

public class LinkedListDemo {
   public static void main(String[] args) {
      LinkedList list = new LinkedList();
      list.add("Hello");
      list.add(2);
      list.add("Chocolate");
      list.add("10");

      System.out.println("LinkedList:" + list);
      Iterator x = list.listIterator(1);

      while (x.hasNext()) {
         System.out.println(x.next());
      }
   }
}

Output

LinkedList:[Hello, 2, Chocolate, 10]
2
Chocolate
10
