Sunrise / Check time

For my app I use a sunriseCalc-lib. This lib calculates the sunrise-time and returns a string like this 12:20. Is it possible to check if the current time is later than the sunrise time? I have the following code:

        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 = newDateFo开发者_JS百科rmat.parse(calculator.getOfficialSunriseForDate(date));
        Date dusk = newDateFormat.parse(calculator.getOfficialSunsetForDate(date));

new Date().after(dawn)

If you have Date objects already just use the before() and after() methods on those objects.
