public class CloneOfArrayList {

public static void main(String[] args) {
ArrayList<String> arr = new ArrayList<String>();
// add element in arraylist
arr.add(“c”);
arr.add(“php”);
arr.add(“html”);
arr.add(“java“);
// print arraylist
System.out.println(“arrayList is = ” + arr);

//Returns a shallow copy of this ArrayList instance
ArrayList<String> clone1 = (ArrayList<String>) arr.clone();
