This section demonstrates how to use the Java Arraylist clone Method.

It returns the copy of the given ArrayList object as the Object class.
So it must be casted to the ArrayList for further use.

Java Arraylist Clone Example

import java.util.*;

public class List1 {

public static void main(String[] args) {
String  ar[]={"india","pakistan","United Kingdom","Japan"};
ArrayList list=new ArrayList();
list.add(ar[0]);
list.add(ar[1]);
list.add(ar[2]);
list.add(ar[3]);
ArrayList list1=(ArrayList)list.clone();

System.out.println(list+"   ");
System.out.println(list1+"   ");
}
}
Output
[india, pakistan, United Kingdom, Japan] 
[india, pakistan, United Kingdom, Japan]
