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]
