Is there a DateFormatProvider that will use Windows localization information?

I'm writing a java gui application that has to display dates.

Since this application is primarily going to run on Windows systems, I would like to be able to use date & time formats that correspond to the Windows localization settings.

I found DateFormatProvider class, in Java 6, which gave me high hopes ... but I haven't found an implementation that will use the Windows localization 开发者_开发百科information.

Any suggestions?

You should be able to use the DateFormatProvider methods with the default locale returned by getDefault().

The Java Virtual Machine sets the default locale during startup based on the host environment.

EDIT: if you can't just pass the default locale to the DateFormat class, there is example code here for implementation of a concrete class that extends DateFormatProvider.

I haven't heard about any Java date formatter that uses MS Windows formatting routines (or just definitions for that matter). Since Java is meant to be multiplatform (compile once, run anywhere), it simply couldn't use underlying OS behavior, for consistency reasons.

You can use DateFormat class as defined here:

DateFormat dateFormatter = DateFormat.getDateInstance(DateFormat.MEDIUM, Locale.getDefault());
String formattedDate = dateFormatter(new Date());

One important issue about this class: LONG date formats are broken for Czech, Polish and Russian, possibly for other Slavic languages too. I recommend using MEDIUM date format instead.

BTW. This will format dates for Gregorian or Julian calendars. It won't give you Arabic nor Hebrew calendars (although former is default for some countries).

Edit

I am not aware of your specific requirements, but since you mentioned Locale, maybe ICU4J's DateFormat class is what you looking for. Still, as per my knowledge (which might be incomplete here), they are using their own formatter and localized text database. However, this database is probably more complete (especially on Mac) than the one bundled with JDK (previous ICU snapshot).
