二维常用分组方法

 public static List<List<String>> packageMQDate(List<String> originalList, int limit)  {
        List<List<String>> dataList = new ArrayList<List<String>>();

        int size = originalList.size();

        //计算按指定数据分组数量
        int totalNum = size / limit;
        int remainder = size % limit;
        // 大循环次数
        if (remainder != 0) {
            totalNum = totalNum + 1;
        }

        //循环封装数据
        for (int i = 0; i < totalNum; i++) {
            // 指定条数
            int count = limit;
            // 假如是最后一次循环且求余不等于0
            if (i == totalNum - 1 && remainder != 0) {
                count = remainder;
            }

            List<String> subList = originalList.subList(i * limit, i * limit + count);
            dataList.add(subList);
        }

        return dataList;
    }
