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
