        TreeSet<Integer> treeSet = new TreeSet<Integer>();

        treeSet.add(10);

        treeSet.add(40);
        treeSet.add(20);
        treeSet.add(30);

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

        /*
         * Returns an iterator over the elements in this set in ascending order.
         */

        Iterator<Integer> iterator = treeSet.iterator();

        while (iterator.hasNext())
        {
            iterator.next();
            /*
             * Removes from the treeSet the last element that was returned by
             * next()
             */
            iterator.remove();
        }

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

Output

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

treeSet : []
