❮ ArrayList Methods

import java.util.ArrayList;public class Main {  public static void main(String[] args) {    ArrayList<String> cars = new ArrayList<String>();    cars.add("Volvo");    cars.add("BMW");    cars.add("Ford");    cars.add("Mazda");        ArrayList cars2 = (ArrayList)cars.clone();    cars2.set(0, "Toyota");        System.out.println(cars);    System.out.println(cars2);  }}

Definition and Usage

Theclone() method returns a copy of theArrayList as anObject.

This creates a "shallow" copy, which means that copies of objects in the list are not created, instead the list has references to the same objects that are in the original list.

Note: Since the return type isObject, it must betype casted in order to use it as anArrayList as shown in the example above.

Syntax

public Object clone()
