java泛型处理，按指定数量拆分List

 public static  List> groupListBySplitCount(List list, int SplitCount) {
        List> retList = new ArrayList<>();
        if (list == null || list.size() == 0) {
            return retList;
        }
        int count = 0;
        while (count < list.size()) {
            retList.add(list.subList(count, (count + SplitCount) > list.size() ? list.size() : (count + SplitCount)));
            count += SplitCount;
        }
        return retList;
    }
