Unsure what get(Calendar.DAY_OF_WEEK) returns

Question

My problem can be easily created by the scenario below:

 //create a gregorian calendar object that set the date and time as 4th June 2012 at 10:30PM
 Calendar calendar = new GregorianCalendar(2012, 6, 4, 22, 30);

 //when I print out these:
 System.out.println(calendar.get(Calendar.DAY_OF_WEEK));
 System.out.println(calendar.get(Calendar.MINUTE));
 System.out.println(calendar.get(Calendar.HOUR));
 System.out.println(calendar.get(Calendar.DATE));
 System.out.println(calendar.get(Calendar.MONTH));
 System.out.println(calendar.get(Calendar.YEAR));

 //output reads as:
 4
 30
 10
 4
 6
 2012

 //so does calendar.get(Calendar.DAY_OF_WEEK) == calendar.get(Calendar.DATE) ???

Just so that everyone is clear the 4th of June 2012 is a Monday, so shouldn't calendar.get(Calendar.DAY_OF_WEEK) return 0 as part of the first day of the week?

Thank for your all your help and concerns, please also verify the source that you are referring to.

Answer 1

The month in java Calendar classes is 0-based. So June is month number 5.

You actually created an object representing July 4th, which happens to be a Wednesday, which is the fourth day of that week.
