Java中一个大数组中小数组合并

怎样将一个大数组中的每七个小数组合并为一个数组放在大数组中，有没有大佬解答一下qaq

jdk1.8 flatMap 应该可以帮到你

数组拆分为 每7个为一组么？

SELECT
	max(case when setting_name ='x' then actual_value end) as "x",
	max(case when setting_name ='a' then actual_value end) as "a",
	max(case when setting_name ='b' then actual_value end) as "b",
	max(case when setting_name ='c' then actual_value end) as "c",
	max(case when setting_name ='d' then actual_value end) as "d",
	max(case when setting_name ='e' then actual_value end) as "e",
	max(case when setting_name ='f' then actual_value end) as "f",
	max(case when setting_name ='g' then create_time end) as "g"
FROM multi_check
where production_id =1
GROUP BY create_time HAVING create_time>0;
