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");

        
        /*
         * Using foreach loop get each element from the HashSet.
         */

        for( String name : hashSet )
        {
            System.out.println(name);
