Java Program to Add an Element to ArrayList using ListIterator Last Updated : 15 Dec, 2020 Comments Improve Suggest changes Like Article Like Report In this article, we will learn how to add an element to ArrayList using ListIterator. The ListIterator is used to return a list iterator over the list elements. The listIterator() returns an iterator over the list from the beginning, but the listIterator(index) returns an iterator over the list from the given index. Syntax: // listIterator() method returns an iterator over the list from the beginning ListIterator<Integer> it = list.listIterator() // listIterator(index) method returns ans iterator over the list from the given index ListIterator<Integer> it = list.listIterator(index); Return Value: This method returns a list iterator over the elements in this list (in proper sequence). Approach: To add an element to ArrayList using Java ListIterator, the process divided into two parts: 1. Make an iterator. ListIterator<Integer> it = list.listIterator() 2. Add element using add() method. it.add(element) Below is the implementation of the above approach: Example 1: Java // Java program to add elements to ArrayList using // ListIterator import java.util.*; public class GFG { public static void main(String[] args) { // New empty ArrayList List<Integer> list = new ArrayList<>(); // Add elements to ArrayList list.add(10); list.add(20); list.add(30); // Print ArrayList before add 50 System.out.println("Before add 50: " + list); // ListIterator ListIterator<Integer> it = list.listIterator(); // iterate ArrayList and add 50 to ArrayList while (it.hasNext()) { // add 50 to ArrayList it.add(50); // move iterator it.next(); } // Print ArrayList after add 50 System.out.println("After add 50: " + list); } } OutputBefore add 50: [10, 20, 30] After add 50: [50, 10, 50, 20, 50, 30] Example 2: Java // Java program to add elements to ArrayList using // ListIterator import java.util.*; public class GFG { public static void main(String[] args) { // New empty ArrayList List<Integer> list = new ArrayList<>(); // Add elements to ArrayList list.add(10); list.add(20); list.add(30); // Print ArrayList before add 50 System.out.println("Before add 50: " + list); // Returns an iterator over the list from the given // index ListIterator<Integer> it = list.listIterator(1); // iterate ArrayList and add 50 to ArrayList while (it.hasNext()) { // add 50 to ArrayList it.add(50); // move iterator it.next(); } // Print ArrayList after add 50 System.out.println("After add 50: " + list); } } OutputBefore add 50: [10, 20, 30] After add 50: [10, 50, 20, 50, 30] Comment More infoAdvertise with us Next Article Java Program to Add an Element to ArrayList using ListIterator K KapilChhipa Follow Improve Article Tags : Java Java Programs Java-ArrayList Practice Tags : Java Similar Reads Java Tutorial Java is a high-level, object-oriented programming language used to build web apps, mobile applications, and enterprise software systems.
