public class TreeSetExample

    public static void main( String[] args )

        treeSet.add(30);
        treeSet.add(10);
        treeSet.add(50);

        System.out.println("treeSet : " + treeSet + "\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 = treeSet.toArray();

        for( Object object : objArray )
        {
            Integer value = (Integer) object;
            System.out.println(value);
        }
    }
}

Output

treeSet : [10, 20, 30, 40, 50]

10
20
30
40
50
