java date problem in parsing

I am parsing a date开发者_C百科, where I am passing 2011-02-10 00:00:00:0, and I am getting 2011-01-10 as the result. Is this wrong? Please help.

 DateFormat df = new SimpleDateFormat("yyyy-mm-dd");
 today = df.parse(datecollection);

The pattern for month is MM: yyyy-MM-dd. You should read the API doc.

You should be using MM not mm. MM is for month, mm is for minute

try using MM instead of mm should work

refer http://download.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html

 M  Month in year   Month   July; Jul; 07
 m  Minute in hour  Number  30

an example

"yyyy-MM-dd HH:mm:ss:SSS"   2001-07-04 12:08:56:235

You need to replace mm with MM. Please take a look at this page.

try
   {
            DateFormat df = new SimpleDateFormat("yyyy-MM-dd"); 
            System.out.println(df.parse("2011-02-10 00:00:00:0"));
   }
   catch (Exception e){}

Prints:

Thu Feb 10 00:00:00 CET 2011
