java8 stream record

Directly on the code

forEach () method, for loop

 

stream (). filter (). collect (Collectors.toList ()) display the required elements, into the corresponding list

stream (). map (WechatUser :: getUin) .collect (Collectors.toList ()) take into list uin

user -> Math.abs (.. Period.between (localDate, user.getLastLoginTime () toLocalDate ()) getDays ())> 89), WechatUser :: getUin anonymous expression, functional programming
