HashSetExample.java
import java.util.HashSet;

/*
 * Example of clone() method.
 */
public class HashSetExample
{
    public static void main( String[] args )
    {
        HashSet<String> hashSet = new HashSet<String>();

        hashSet.add("Dave");
        hashSet.add("Peter");
        hashSet.add("Phil");
        hashSet.add("Rohit");
        hashSet.add("Virat");

        System.out.println("hashSet: " + hashSet + "\n");

        /*
         * Returns a shallow copy of this HashSet instance: the elements
         * themselves are not cloned.
         */
        HashSet<String> clonedHashSet = (HashSet<String>) hashSet.clone();

        System.out.println("clonedHashSet : " + clonedHashSet);

    }
}

Output
hashSet: [Rohit, Dave, Phil, Peter, Virat]

clonedHashSet : [Rohit, Peter, Virat, Dave, Phil]
