It has an overload of the Collections.sort() method that receives a Comparator object as its second parameter ( documentation ), and the Collections class itself has another method that returns a comparator object that imposes a reverse order on the list, Collections.reverseOrder() ( documentation ).

The code looks like this:

Collections.sort(lista, Collections.reverseOrder());
