Why the current year in the date saved as 3912?

Question

to get the current date and time

final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
mHour = c.get(Calendar.HOUR_OF_DAY);
mMinute = c.get(Calendar.MINUTE);

to create current date object

Date toDate;
     toDate.setYear(mYear);
     toDate.setMonth(mMonth);
     toDate.setDate(mDay);



Date endDate = toDate;

when printing endDate object I got

Mon Jan 01 13:11:00 GMT+03:00 3912

why ?

Answer 1

From Date.setYear(int) description: Sets the gregorian calendar year since 1900 for this Date object. Thus, 1900 + 2012 = 3912.

But calendar.get(Calendar.YEAR) returns exact year number 2012. So this inconsistency of API causes your issue. But anyway Date.setYear(int) is deprecated, thus, it is better to use Calendar object for date calculations.
