But thanks for the hint; in case you have an object which implements Comparable interface reverseOrder() looks easier.

It is really easy to make an error when writing one, better to rely on provided and well tested libraries. Use Collections.sort(list, Collections.reverseOrder()) to sort a list of integers in a reverse order.
