Cannot set correct year by using Calendar in Java

Question

I have the following code and want to set cal to 01.01.2016.

DateFormat dateFormat = new SimpleDateFormat("dd.MM.YYYY");
Calendar cal = Calendar.getInstance();
cal.set(2016, Calendar.JANUARY, 1);
System.out.println(dateFormat.format(cal.getTime()));

But it always return 01.01.2015. I tried to set year to 2017, it outputs 2016. For 2015, 2014 and 2018, it works correctly.

year should have small 'y': yyyy – Michel_T. Nov 22 '16 at 11:31 — Michel_T., Nov 22 '16 at 11:31

The year in format must be an lower case y

DateFormat dateFormat = new SimpleDateFormat("dd.MM.yyyy");

Upper case Y is for Week year.

For more details see the java doc of SimpleDateFormat
