Resolving a non-static cannot be referenced from a static context error

[John Bowling]

I'm trying to get the day of month with:

int dayofmonth;
dayofmonth = Calendar.get(Calendar.DAY_OF_MONTH);

and I get the compile time error of saying get(int) is a not-static method.

Is there a process (or a different class/method to call) that will work?

Thanks, John

Hi John,

When get is not defined as static this means that you have to create a
GregorianCalendar object and call get on that; I guess this is because the
creators of the class wanted programmers to be able to give the calendar
their own layout.

Here is an example on how to set up a GregorianCalendar object (most is from Java's API):

String[] ids = TimeZone.getAvailableIDs(1 * 60 * 60 * 1000);
if (ids.length == 0)
System.exit(0);
SimpleTimeZone pdt = new SimpleTimeZone(1 * 60 * 60 * 1000, ids[0]);
pdt.setStartRule(Calendar.APRIL, 1, Calendar.SUNDAY, 2 * 60 * 60 * 1000);
pdt.setEndRule(Calendar.OCTOBER, -1, Calendar.SUNDAY, 2 * 60 * 60 * 1000);
GregorianCalendar calendar = new GregorianCalendar(pdt);
calendar.setTime(new java.util.Date());

int dayofmonth = calendar.get(Calendar.DAY_OF_MONTH);

Best Regard
Kristian

That solved it.
Thanks, John

It can be done with the Calendar class. You can even create the object with
the same name, so that it works as asked.

import java.util.*;

class calendar {
static public void main(String args[]) {
Calendar Calendar=java.util.Calendar.getInstance();
System.out.println(Calendar.get(Calendar.DAY_OF_WE EK));
}

Some people will suggest giving the object reference variable a different
name, though.
