我有以下表达式:

scheduleIntervalContainers.stream()
        .filter(sic -> ((ScheduleIntervalContainer) sic).getStartTime() != ((ScheduleIntervalContainer)sic).getEndTime())
        .collect(Collectors.toList());

... scheduleIntervalContainers元素类型在哪里ScheduleContainer:

final List<ScheduleContainer> scheduleIntervalContainers

是否可以在过滤器之前检查类型？
