比较map的value

Collection<CardInfo> values = splitCardInfo.getCardType().values();
Iterator<CardInfo> iterator = values.iterator();
List<Integer> list = new ArrayList<>();
while (iterator.hasNext()){
    if (list.isEmpty()){
        list.addAll(iterator.next().getCards());
    } else {
        resultList.addAll(list.size() > iterator.next().getCards().size() ? list:
                iterator.next().getCards());
        break;
    }
}
