Program Plan Intro

Program:

//package to use clone() method

package language;

//import cloneable interface

import java.lang.Cloneable;

import java.lang.String;

import java.lang.System;

//class definition

class ArrayList implements Cloneable

{

// main method declaration

public static void main(String args[])

{

// create new array

ArrayList<String> list = new ArrayList<>();

// add elements into the array

list.add("New York");

// create new ArrayList

ArrayList<String> list1 = list;

// using cloning create another array

ArrayList<String> list2 = (ArrayList<String>) (list.clone());

// add elements

list.add("Atlanta");

// compare the three array elements

System.out.println(list == list1);

System.out.println(list == list2);

//Display the list

System.out.println("list is " + list);

//Display the list1

System.out.println("list1 is " + list1);

//Call get() method and then display the list2

System.out.println("list2.get(0) is " + list2.get(0));

//Call size() method and then display the list2

System.out.println("list2.size() is " + list2.size());

}
