public class LinkedHashSetExample
{
    public static void main( String[] args )
    {
        LinkedHashSet<String> linkedHashSet = new LinkedHashSet<String>();

        linkedHashSet.add("Dave");
        linkedHashSet.add("Peter");
        linkedHashSet.add("Juli");
        linkedHashSet.add("Rohit");
        linkedHashSet.add("Virat");

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

        /*
         * Returns the number of elements in this set (its cardinality).
         */
        int size = linkedHashSet.size();
        
        System.out.println("size : "+size);

    }
