LinkedList listIterator() Method in Java

LinkedList listIterator()

The Java.util.LinkedList.listIterator() method returns a list-iterator containing the same elements as that of the LinkedList and in the same sequence starting from a specific position or index number. The position or index is passed as a parameter to the function.

Syntax

ListIterator new_list = LinkedList.listIterator(int index);

Parameter: A parameter is an integer number that indicates the element from which ListIterator begins functioning and returning values.

Return value: The method returns a sub-list of the original starting from the specified index.

Example

import java.io.*;
import java.util.LinkedList;
import java.util.ListIterator;
  
public class LinkedListTest {
    public static void main(String args[])
    {
       //creating a demo list
        LinkedList<String> demoList = new LinkedList<String>();
  
        // Using add() method to add elements in the demoList 
        demoList .add("Coding");
        demoList .add("Ninjas");
        demoList .add("Studio");
        demoList .add("10");
        demoList .add("20");
  
        // Displaying the linkedlist
        System.out.println("LinkedList items:" + list);
          
        // Setting the ListIterator at a specified index
        ListIterator listIter = demoList .listIterator(2);
  
        // Iterating through the new list from the position
        System.out.println("The list using listIterator is as follows:");
        while(listIter.hasNext()){
           System.out.println(listIter.next());
        }
    }
}
