Before using lamda

Collections.sort(logs, new Comparator<FaceRecognition>() {
    @Override
    public int compare(FaceRecognition o1, FaceRecognition o2) {
        Float f1 = o1.getScore();
        Float f2 = o2.getScore();
        return f2.compareTo(f1);
    }
});

After using lamda

Collections.sort(logs, (o1, o2) -> {
   Float f1 = o1.getScore();
   Float f2 = o2.getScore();
   return f2.compareTo(f1);
});
