        List<Map.Entry<TbDiseases, Double>> list = new ArrayList<Map.Entry<TbDiseases,Double>>(disMap.entrySet());
        Collections.sort(list, new Comparator<Map.Entry<TbDiseases, Double>>() {
            @Override
            public int compare(Entry<TbDiseases, Double> o1,
                    Entry<TbDiseases, Double> o2) {
                return o2.getValue().compareTo(o1.getValue());
            }
        });
