How do I format a Currency for a Locale in Java

问题

I'm surprised that I'm having real trouble finding how to do this. It seems to me it should be pretty straightforward. Perhaps I'm looking in the wrong place.

Suppose I have the following code:

double amount = 123.45D; //yes, I know that I should be using longs
Locale uk = Locale.UK;
Locale fr = Locale.FR;
Currency euro = Currency.getInstance("EUR");

How do I get instances of NumberFormat that let me print out the 123.45 value correctly formatted for the Locale? ie I want the following for the UK and France respectively :

€123.45
123,45 €

I can't use NumberFormat.getCurrencyInstance(Locale) as that will format the UK format as Sterling (£). What I am looking for is NumberFormat.getCurrencyInstance(Locale, Currency), but that doesn't seem to exist.

Any ideas?

Use NumberFormat.setCurrency() to modify the currency used for a specific NumberFormat acquired via NumberFormat.getCurrencyInstance(Locale).
