Convertring data
Hi,
I have problem with convertring data... I get with my database date :
Date data = user.getDate();// return date object
now I must parse this date to format yyyy-mm-dd so :
DateFormat df = DateFormat.getDateInstance();
String sDate = df.format(data);
and format is ok.... but now I must convert this string to date because another metohod need object date in format (yyyy-mm-dd)... so I do :
Date dtTmp = new SimpleDateFormat("yyyy-mm-dd").parse(sDate);
System.out.print(dtTmp+"\n");
but when I print this date I get : Fri Jan 05 00:04:00 CET 2007 and the metod which use object data isn`t work because to good format must be 2007/mm/dd
How I can do this ?

That will format the date into a locale specific format, so you should always specify the pattern to use.

Take a look at the javadoc for SimpleDateFormat, your pattern is not correct.
Do also note that System.out.println on a Date always will print it in a locale specific format. A Date object does not contain format information.

See above.

Did you see what I said about System.out.println on a date? It will always print the same. You can't change the format of a Date.
Yes, you should use M instead of m for month.

It looks like you don't understand what a date is. A date is milliseconds since 1 jan 1970, and it will always be that, it doesn't matter if you try to convert etc.
You should always use SimpleDateFormat when you want to convert to a String for presentation. toString on a date will always print the date in a locale specific format.
