The iterator() method of CopyOnWriteArrayList in Java

The iterator() method is used to return an iterator over the elements in this list.

The syntax is as follows

Iterator<E> iterator()

To work with CopyOnWriteArrayList class, you need to import the following package

import java.util.concurrent.CopyOnWriteArrayList;

The following is an example to implement CopyOnWriteArrayList class iterator() method in Java

Example

 Live Demo

import java.util.Arrays; import java.util.Iterator; import java.util.concurrent.CopyOnWriteArrayList; public class Demo {    public static void main(String[] args) {       CopyOnWriteArrayList<Integer>       arrList = new CopyOnWriteArrayList<Integer>();       arrList.add(50);       arrList.add(90);       arrList.add(150);       arrList.add(200);       arrList.add(350);       arrList.add(500);       arrList.add(650);       System.out.println("CopyOnWriteArrayList String Representation = " + arrList.toString());       Iterator i = arrList.iterator();       System.out.println("Iterating...");       while (i.hasNext()) {          System.out.println(i.next());       }    } }

Output

CopyOnWriteArrayList String Representation = [50, 90, 150, 200, 350, 500, 650] Iterating... 50 90 150 200 350 500 650
