Jodatime: how to print 4-digit year?

I'm using Jodatime for format a date, and with it I'm using a locale to format it locale-specific. I want my date to be formatted like "17/06/2013" (the separators must depend on the locale), which I can almost achieve with


which gives "17/06/13" (2-digit year). The style "M-" gives "17 juin 2013" (locale French), which is also not what I want.

Of course I can create a formatter with a pattern like "dd/MM/yyyy", which will give me a 4-digit year, but it is not locale-sensitive.

I have been looking for a way to modify the formatter created with the "S-" style, but it doesn't seem to be possible.

What would be the easiest way to get a formatter with this behaviour?

Just get the pattern for the localized short style and replace "yy" with "yyyy" if it's not already present.

String pattern = DateTimeFormat.patternForStyle("S-", locale);
if (!pattern.contains("yyyy")) {
    pattern = pattern.replace("yy", "yyyy");
DateTimeFormatter formatter = DateTimeFormat.forPattern(pattern);
