java - list操作

List newList = list.stream().filter(t -> t.getStatus() == FunctionStatusEnum.OPEN).collect(Collectors.toList());
newList.sort((o2, o1) -> o1.getStatus().getCode().compareTo(o2.getStatus().getCode()));

Paging page = content.getPaging();
Long size = (long) jsonObject.size();
Integer pageStart = (int) ((page.getCurrent() - 1) * page.getSize());
Integer pageEnd = (int) (page.getCurrent() * page.getSize());
pageEnd = pageEnd > jsonObject.size() ? jsonObject.size() : pageEnd;
jsonObject = jsonObject.subList(pageStart, pageEnd);
return Result.build(jsonObject, BizCode.SUCCESS, size);
