Java – iterate between two dates, including the start date?

Sorry for asking repeated questions

public static void main(String[] args)throws Exception {
    GregorianCalendar gcal = new GregorianCalendar();
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy.MM");
    Date start = sdf.parse("2010.01");
    Date end = sdf.parse("2010.04");
    gcal.setTime(start);
    while (gcal.getTime().before(end)) {
        gcal.add(Calendar.MONTH,1);
        Date d = gcal.getTime();
        System.out.println(d);
    }
}

Between the above code print date, but I need to print the start date also

The code output above is

Mon Feb 01 00:00:00 IST 2010
Mon Mar 01 00:00:00 IST 2010
Thu Apr 01 00:00:00 IST 2010

But I also need to start dating on the output

Please help me solve this problem and thank you in advance

Solution

In my opinion, this is the best way:

SimpleDateFormat sdf = new SimpleDateFormat("yyyy.MM");
Date start = sdf.parse("2010.01");
Date end = sdf.parse("2010.04");

GregorianCalendar gcal = new GregorianCalendar();
gcal.setTime(start);

while (!gcal.getTime().after(end)) {
    Date d = gcal.getTime();
    System.out.println(d);
    gcal.add(Calendar.MONTH,1);
}

Output:

Fri Jan 01 00:00:00 WST 2010
Mon Feb 01 00:00:00 WST 2010
Mon Mar 01 00:00:00 WST 2010
Thu Apr 01 00:00:00 WST 2010

All we do is print the date before increment, and then repeat if the date is not after the end date

Another option is to copy the print code before while (yuck) or use do... While (also yuck)
