Collections.sort(list, new Comparator<PriceTypeSkuNum>() {
            @Override
            public int compare(PriceTypeSkuNum o1, PriceTypeSkuNum o2) {
                if(o1.getPrice() > o2.getPrice()){
                    return 1;
                }
                if(o1.getPrice() == o2.getPrice()){
                    return 0;
                }
                return -1;
            }
        });
