The clone() method of CopyOnWriteArrayList method in Java

To return a shallow copy of the CopyOnWriteArrayList, use the clone() method.

The syntax is as follows:

public Object clone()

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 clone() method in Java:

Example

 Live Demo

import java.util.concurrent.CopyOnWriteArrayList; public class Demo {    public static void main(String[] args) {       CopyOnWriteArrayList<Integer> arrList = new CopyOnWriteArrayList<Integer>();       arrList.add(30);       arrList.add(90);       arrList.add(80);       arrList.add(70);       arrList.add(90);       arrList.add(100);       arrList.add(120);       System.out.println("CopyOnWriteArrayList = " + arrList);       System.out.println("Cloned CopyOnWriteArrayList = " + arrList.clone());    } }

Output

CopyOnWriteArrayList = [30, 90, 80, 70, 90, 100, 120] Cloned CopyOnWriteArrayList = [30, 90, 80, 70, 90, 100, 120]
