So I am trying to take a Date object and convert it into a calendar for
use in my application, the code looks like: The string _s comes in in
the format YYYY-MM-DD this i am 100% sure of

    public CalendarInfo(String _s) {
        DateFormat _formatter = new SimpleDateFormat("yyyy-MM-dd");
        try {
            _date = _formatter.parse(_s);
            _calendar = new GregorianCalendar();
            _calendar.clear();
            _calendar.setTime(_date);
                    _log.log_error(_class, "CalendarInfo():
"+_calendar.toString());
                        _log.log_warning(_class, ""+_calendar.YEAR);
                        _log.log_warning(_class, ""+_calendar.MONTH);
                        _log.log_warning(_class,
""+_calendar.DAY_OF_MONTH);
            }
        catch (java.text.ParseException Ex) {
            _log.log_error(_class, "CalendarInfo(): Bad Parse: "+Ex);
        }
    }

So what i am doing is passing in a string formatted as "2006-10-12" and
converting it to a calendar and this is the results i get:

as you can see from the _calendar.toString() call, it clearly shows the
object year 06, month=9, day=12
but when i call the direct Calendar.YEAR/MONTH/DAY_OF_MONTH i get
these weird results.

what is up with that? anyone have any clue? Thanks!


RTFM :-) - try calendar.get(Calendar.YEAR) et al.
Admittely, this is one of Suns more bizarre APIS, so this is easy to
dismiss for first time users...
