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
