SimpleDateFormat函数解析（String s）给出错误的日期

Question

As an input I have Date object(for example, exDate=Fri Aug 01 00:00:00 EEST 2014) that must be formated. After the parsing of the date, I get wrong date.

            SimpleDateFormat sdf = new SimpleDateFormat(
                    "dd-MMM-YYYY hh.mm.ss.SSSSSSSSS aa", Locale.ENGLISH);
            String dateStart = sdf.format(exDate);
            Date dateF = sdf.parse(dateStart);

dateStart will be equal to

01-Aug-2014 12.00.00.000000000 AM 

and the resut, dateF will be equal to

Sun Dec 29 00:00:00 EET 2013

So, after the parsing of a string with date, the result is wrong. Maybe, somebody know the source of the problem? Or another way to format date in another SimpleDateFormat ?

Answer 1

The problem is the YYYY which means :

 Y   Week year;

The actual year, which is what you are looking for would be yyyy .

I really recommend that you go in the link above to see the full list .

You should also replace the milliseconds to .SSS as you can't get more precise than that.
