Y returns 2012 while y returns 2011 in SimpleDateFormat

Question

I wonder why \'Y\' returns 2012 while \'y\' returns 2011 in SimpleDateFormat:

System.out.println(new SimpleDateFormat(\"Y\").format(new Date()))         


        

Answer 1

Format Y to get week year if calendar support week year. (getCalendar().isWeekDateSupported())
