java - 日出/检查时间

Question

对于我的应用程序，我使用 sunriseCalc-lib。这个库计算日出时间并返回像这样的字符串 12:20。是否可以检查当前时间是否晚于日出时间？我有以下代码:

        Location location = new Location("52.3496752", "4.6211921");
        DateFormat newDateFormat = new SimpleDateFormat("HH:mm");
        SunriseSunsetCalculator calculator = new SunriseSunsetCalculator(location, "Europe/Berlin");
        Calendar date = Calendar.getInstance();

        Date dawn = newDateFormat.parse(calculator.getOfficialSunriseForDate(date));
        Date dusk = newDateFormat.parse(calculator.getOfficialSunsetForDate(date));

Answer 1

new Date().after(dawn)
