java - Issue with SimpleDateFormat

Question

I am working on date format with SimpleDateFormat. But when I format my date in provide format, year value increment by 1.The condition happen with that value. Why this happen?

SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-YYYY");
System.out.println("dob - "+date); // Java date
System.out.println("formatted date - "+sdf.format(date));

Output as follows :

dob - Sun Dec 28 00:00:00 IST 1975
formatted date - 28-12-1976

Year value increment by 1. Why this happen.

Answer 1

As per Oracle docs

capital Y means week year,you should use yyyy in place of YYYY

change SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-YYYY"); to

SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy");
