这段代码是 Kotlin 语言的代码，可以转化为 Java 语言的代码，如下所示：

Comparator<StatusBarNotification> notificationComparator = new Comparator<StatusBarNotification>() {
    @Override
    public int compare(StatusBarNotification a, StatusBarNotification b) {
        boolean aHeadsUp = isHeadsUp(a);

        boolean aMedia = isMediaNotification(a);
        boolean bMedia = isMediaNotification(b);
        boolean aSystemMax = a.getNotification().priority == Notification.PRIORITY_MAX;
        boolean bSystemMax = b.getNotification().priority == Notification.PRIORITY_MAX;
        boolean aIsHighPriority = a.getNotification().priority >= Notification.PRIORITY_HIGH;
        boolean bIsHighPriority = b.getNotification().priority >= Notification.PRIORITY_HIGH;
        int aRank = getRank(a);
        int bRank = getRank(b);
        int result = 0;
        if (aHeadsUp != bHeadsUp) {
            result = aHeadsUp ? -1 : 1;
        } else if (aHeadsUp) {
            result = headsUpManager.compare(a, b);
        } else if (aIsFsn != bIsFsn) {
            result = aIsFsn ? -1 : 1;
        } else if (usePeopleFiltering && a.getNotification().extras != null &&
                b.getNotification().extras != null) {
            String aPersonType = a.getNotification().extras.getString(EXTRA_PEOPLE_TYPE);
            String bPersonType = b.getNotification().extras.getString(EXTRA_PEOPLE_TYPE);
            if (aPersonType != null && bPersonType != null &&
                    !aPersonType.equals(bPersonType)) {
                result = peopleNotificationIdentifier.compareTo(aPersonType, bPersonType);
            }
        }

                result = aSystemMax ? -1 : 1;
            } else if (aIsHighPriority != bIsHighPriority) {
                result = -1 * Boolean.compare(aIsHighPriority, bIsHighPriority);
            } else if (aRank != bRank) {
                result = aRank - bRank;
            } else {
                result = Long.compare(b.getNotification().when, a.getNotification().when);
            }
        }
        return result;
    }
};
