Understanding java.util.Calendar WEEK_OF_YEAR [duplicate]

The following code calculates the workweek of a specific date.
DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Calendar cal = new GregorianCalendar();
cal.setTime(df.parse("2015-12-27 08:00:00"));
System.err.printf("%d.%02d\n", cal.getWeekYear(), cal.get(Calendar.WEEK_OF_YEAR));
It currently prints 2016.01.
As I understand the work week number specification, 2016.01 is the first week having 4 days in 2016, but there is no way December 27 can belong to such week.
Is there a way to do it in Java 7 which will work for any year assuming weeks start on Monday?
Try setting Monday as first day of the week.
cal.setFirstDayOfWeek(Calendar.MONDAY);

I have searched a lot on internet about how to get current time in Java but what I am looking for is how to get current time + n months?
You can try like this:
Calendar cal = Calendar.getInstance();
cal.add(Calendar.MONTH, numberofMonths);
If you can use Java 8, use LocalDate.plusMonths()
LocalDate localDate = LocalDate.now();
localDate.plusMonths(numberOfMonths);
