LinkedHashSetExample.java
import java.util.LinkedHashSet;

/*
 * Example of toArray(T[] a) method.
 */
public class LinkedHashSetExample
{
    public static void main( String[] args )
    {
        LinkedHashSet<String> linkedHashSet = new LinkedHashSet<String>();

        linkedHashSet.add("Rohan");
        linkedHashSet.add("Phil");
        linkedHashSet.add("Ram");
        linkedHashSet.add("Dave");
        linkedHashSet.add("Peter");

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

        String[] strArray = new String[linkedHashSet.size()];

        /*
         * linkedHashSet elements will be copied to StrArray
         */

        linkedHashSet.toArray(strArray);

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

    }
