Example

 Live Demo

import java.util.Arrays;
import java.util.concurrent.CopyOnWriteArrayList;

public class Demo {
   public static void main(String[] args) {
      CopyOnWriteArrayList<Integer> arrList = new CopyOnWriteArrayList<Integer>();
      arrList.add(220);
      arrList.add(250);
      arrList.add(400);
      arrList.add(500);
      arrList.add(650);
      arrList.add(700);
      arrList.add(800);
      System.out.println("CopyOnWriteArrayList String Representation = " + arrList.toString());
      Object[] myArr = arrList.toArray();
      System.out.println("Array = "+Arrays.toString(myArr));
   }
}

Output

CopyOnWriteArrayList String Representation = [220, 250, 400, 500, 650, 700, 800]
Array = [220, 250, 400, 500, 650, 700, 800]
