I wrote down all the examples, don’t match up with the tutorial, or Java documentation. 
The only place I had any issues was the DAY_Of_MONTH type format which even on the tutorial sites does not work as stated.  I seem to recall, that there was an extra step to get the right numbers but I don’t see any examples of it.

Date d = new Date();
Calendar c1 = Calendar.getInstance();
c1.setTime(d); 

System.out.println(" " + c1.DAY_OF_MONTH + " Field number ... indicating the day of the month.");System.out.println(" " + c1.DAY_OF_WEEK + " Field number ... indicating the day of the week.");

System.out.println(" " + c1.DAY_OF_WEEK_IN_MONTH + " Field number ... indicating the ordinal number of the day of the week within the current month.");

System.out.println(" " + c1.DAY_OF_YEAR + " Field number ... indicating the day number within the current year."); 

System.out.println(" " + c1.WEEK_OF_MONTH + " Field number ... indicating the week number within the current month."); 

System.out.println(" " + c1.WEEK_OF_YEAR + " Field number ... indicating the week number within the current year."); System.out.println(" " + c1.YEAR + " Field number ... indicating the year.");
