AbstractList listIterator() Method in Java with Examples

The listIterator() method of java.util.AbstractList class is used to return a list-iterator containing the same elements as that of the AbstractList in proper and same sequence starting from a specific position or index number which is passed as a parameter to this method.

Syntax:

ListIterator new_list 
          = AbstractList.listIterator(int index);

Parameters: The parameter index is an integer type value that specifies the position of the element from where ListIterator starts operating and returning values.

Return Value: The method returns the list created using ListIterator, starting from the specified index.

Below program illustrate the AbstractList.listIterator() method:

Program 1:

// Java code to illustrate listIterator()

import java.util.*;

public class LinkedListDemo {
    public static void main(String args[])
    {

        // Creating an empty AbstractList
        AbstractList<String>
            abs_list = new LinkedList<String>();

        // Use add() method to add elements in the list
        abs_list.add("Geeks");
        abs_list.add("for");
        abs_list.add("Geeks");
        abs_list.add("10");
        abs_list.add("20");

        // Displaying the AbstractList
        System.out.println("AbstractList:" + abs_list);

        // Setting the ListIterator at a specified position
        ListIterator list_Iter = abs_list.listIterator(2);

        // Iterating through the created list from the position
        System.out.println("The list is as follows:");

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

Output:

AbstractList:[Geeks, for, Geeks, 10, 20]
The list is as follows:
Geeks
10
20

Program 2:

// Java code to illustrate listIterator()

import java.util.*;

public class LinkedListDemo {
    public static void main(String args[])
    {

        // Creating an empty AbstractList
        AbstractList<Integer>
            abs_list = new LinkedList<Integer>();

        // Use add() method to add elements in the list
        abs_list.add(10);
        abs_list.add(20);
        abs_list.add(30);
        abs_list.add(40);
        abs_list.add(50);

        // Displaying the AbstractList
        System.out.println("AbstractList:" + abs_list);

        // Setting the ListIterator at a specified position
        ListIterator list_Iter = abs_list.listIterator(2);

        // Iterating through the created list from the position
        System.out.println("The list is as follows:");

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

Output:

AbstractList:[10, 20, 30, 40, 50]
The list is as follows:
30
40
50
