将以下c#代码转为java代码 public virtual void AreaChangedResetPriceListRoom roomList ListRoom oldRoomList if roomList == null roomListCount == 0 return; ListPriceC

public void AreaChangedResetPrice(List roomList, List oldRoomList) { if (roomList == null || roomList.size() == 0) return; List priceChgLogs = new ArrayList<>();

ParamsRoomInfoDto paramsRoomInfoDto = _iParamSetttingPublicService.Instance.GetRoomInfoParams(roomList.get(0).getProjGUID());
//0.计算价格信息，以及生成价格修改日志信息
for (Room room : roomList) {
    Room item = oldRoomList.stream().filter(r -> r.getRoomGUID().equals(room.getRoomGUID())).findFirst().orElse(null);
    if (item != null) {
        PriceHelper.CalcRoomPrice(room, paramsRoomInfoDto);
        room.setIsAreaModify(0);
        _priceAggregateService.Instance.GetRoomPriceChanged(room, item, priceChgLogs);
    }
}
//1.更新房间
_publicServiceToolTools.RoomGeneratePublicService.BatchUpdateRooms(roomList);
//2.价格管控更新新增价格信息
if (!priceChgLogs.isEmpty()) {
    _backgroundJobManager.Enqueue(new CreatePriceChgBatchJobArg(priceChgLogs));
}
