Problem in date format

**Vodka** · 19-02-2010

Hello,
I need to format dates depending on the locale. These dates must be in digital format. DateFormat that almost meets my needs:

Code:

DateFormat df = DateFormat.getDateInstance(DateFormat.SHORT);

The problem is that it only takes 2 figures in account for the year and I need 4. Someone would have any idea please? Thank you.

Hello,
I do not know what format DateFormat.short but you can SimpleDateFormat formatter as you like:
For example:
Code:

Code:

SimpleDateFormat s = new SimpleDateFormat("YYYYMMDD");
System.out.System.out.println(s.format(new Date()));

I hope this will help you.

Hello,
Your solution is good but I do not think this is what will help him, because you lose all the information moves on the local ... It will display the date in short format according to the usual local user, ie:

* dd / MM / yy for en_US
MM-dd-yy for en_US
etc. ...

This is possible through the method DateFormat.getDateInstance ()

Hello,
One solution would be to change the pattern returned ... It seems that it is therefore an object SimpleDateFormat the following code should do the trick:

Code:

       DateFormat dtfr = DateFormat.getDateInstance(DateFormat.SHORT);
       if (dtfr instanceof SimpleDateFormat) {
           SimpleDateFormat sdtfr = (SimpleDateFormat) dtfr;
           String ptr = sdtfr.toLocalizedPattern();
           if (ptr.indexOf(yyyy)==-1) {
               dtfr = new SimpleDateFormat(ptr.replaceFirst("yy", yyyy));
           }
       }

If the returned object is not a SimpleDateFormat can not do anything.
Otherwise we create a new SimpleDateFormat with 4-digit year if it is not the case.

Hello,
I have this temporary solution to almost exactly:
Instead of:

Code:

if (ptr.indexOf(yyyy)==-1) {
               df = new SimpleDateFormat(ptr.replaceFirst("yy", yyyy));
           }

Code:

df = new SimpleDateFormat(pattern.replaceFirst("y +", yyyy));

I thought there was a less circuitous way to achieve what I want.

Hello,
Actually re-reading the post it is specified and said: "depending on the locale," I therefore advise every beginner in java to be sure to read before going to Java and especially before trying to do some example, I feel so because every programmer should have the basic knowledge strong , that it the basics of the language should be strong.
