Gregorian calendar issue

[orchid]

Something is not right with my code.

Code:

ArrayList<DayEntry> month = new ArrayList<DayEntry>();

int now_month = 9;
 
while(days.hasNext()) {
    Map<String,Object> row = days.next();
    Date in = (Date) row.get(DayType.DATE);
    GregorianCalendar date = new GregorianCalendar();
    date.setTime(in);
    if(date.get(Calendar.MONTH) == now_month) {
        String entry = (String) row.get(DayType.ENTRY);
        month.add(new DayEntry(entry,date));
    }
}

I first thought there was something up with my previous code regarding the days iterator, but on close inspection it appears there is something up with the GregorianCalendar...

System.out.println(in) prints ....
Wed Sep 27 15:09:58 GMT 2006

System.out.println(date.getTime()) prints .....
Wed Sep 27 15:09:58 GMT 2006

BUT, System.out.println(date.get(Calendar.MONTH)) print ....
8
and i am pretty sure Sep is the 9th month of the year.
Thanks

The months are zero indexed (who knows why.....!!!)
Best to use the Calendar constants rather than rely on int literals; e.g., Calendar.SEPTEMBER.
