LinkedHashSetExample.java
import java.util.LinkedHashSet;

/*
 * Example of toArray() 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");

        /*
         * Returns an array containing all of the elements in this set. 
         * 
         * This method acts as bridge between array-based and collection-based APIs.
         */

        Object[] objArray = linkedHashSet.toArray();

        for( Object object : objArray )
        {
            String name = (String) object;
            System.out.println(name);
        }

    }
}

Output
linkedHashSet : [Rohan, Phil, Ram, Dave, Peter]

Rohan
Phil
Ram
Dave
Peter
