Im trying to set the month and date of a Gregorian Calendar:
GregorianCalendar startCalendar = new GregorianCalendar();
startCalendar.set(GregorianCalendar.MONTH, 3);
System.out.println(startCalendar.MONTH);
startCalendar.set(GregorianCalendar.DATE, 9);
System.out.println(startCalendar.DATE);
The output is:
2
5
It doesn't seem to matter which numbers i use (ie. if i replace the 3 and 9), it always has the same output
References:
MONTH
and DATE
are field numbers and aren't the actual value of the fields. You should use get()
method to get the number set.
GregorianCalendar startCalendar = new GregorianCalendar();
startCalendar.set(GregorianCalendar.MONTH, 3);
System.out.println(startCalendar.get(GregorianCalendar.MONTH));
startCalendar.set(GregorianCalendar.DATE, 9);
System.out.println(startCalendar.get(GregorianCalendar.DATE));
startCalendar.MONTH
is the same as Calendar.MONTH
, and is a static field declared in the Calendar
class as:
public final static int MONTH = 2;
To get the month from the calendar, you need to call get()
:
startCalendar.get(Calendar.MONTH)
Note that you should always qualify static fields by the actual class declaring them (eg Calendar.MONTH
), never by a reference variable (eg startCalendar.MONTH
) and never by subclass (eg GregorianCalendar.MONTH
).
So, your code should be:
GregorianCalendar startCalendar = new GregorianCalendar();
startCalendar.set(Calendar.MONTH, 3);
System.out.println(startCalendar.get(Calendar.MONTH));
startCalendar.set(Calendar.DATE, 9);
System.out.println(startCalendar.get(Calendar.DATE));
