不能在数字格式中使用特定的语言环境

Question

I just want to use danish as the locale when getting a currency numberformat ( where it says French now ) but no locale "code" can be used for it.

NumberFormat.getCurrencyInstance(Locale.FRENCH).format(pay);

When I check out the getAvailableLocales() method I get several that mention DK : da_DK_#Latn , da_DK , en_DK , fo_DK but the locale code just appears red in the code and the IDE says "Rename reference" .

Only "big" languages show up such as french and can be used.

I don't know how to use a locale that isn't one of the big languages that automatically pop up as suggestions when you write the function.

There is no constant in the Locale class for the locale that you are looking for, but you can instantiate it using one of the constructors defined by this class.

To get the proper formatting for the currency, need a constructor that expects two string arguments: language and country codes.

Locale locale = new Locale("da", "DK");
NumberFormat currencyFormat = NumberFormat.getCurrencyInstance(locale);
System.out.println(currencyFormat.format(1000));
