如何使用比較器以多個時間戳記對 Java 物件清單進行排序？

List<ActiveAlarm> alarms = new ArrayList<>();

// Custom comparator to compare ActiveAlarm instances based on timeStarted and timeEnded
Comparator<ActiveAlarm> comparator = new Comparator<ActiveAlarm>() {
    @Override
    public int compare(ActiveAlarm o1, ActiveAlarm o2) {
        // First compare timeStarted
        int comparisonResult = Long.compare(o1.timeStarted, o2.timeStarted);
        // If timeStarted is equal, compare timeEnded
        if (comparisonResult == 0) {
            comparisonResult = Long.compare(o1.timeEnded, o2.timeEnded);
        }
        return comparisonResult;
    }
};

// Sort the list of alarms using the comparator
Collections.sort(alarms, comparator);

Comparator<ActiveAlarm> comparator = (o1, o2) -> {
    int comparisonResult = Long.compare(o1.timeStarted, o2.timeStarted);
    if (comparisonResult == 0) {
        comparisonResult = Long.compare(o1.timeEnded, o2.timeEnded);
    }
    return comparisonResult;
};
