Get All Possible Available Currencies

Question

I would like to get all possible available currencies.

Java 7 had provided such feature.

public static Set java.util.Currency.g         


        

Answer 1

After studying the ISO table and the Currency class documentation, it seems that you can ask for currency as code or as Locale; and the class Locale has a getAvailableLocales() method.

So, the code would be:

    public static Set getAllCurrencies()
    {
        Set toret = new HashSet();
        Locale[] locs = Locale.getAvailableLocales();

        for(Locale loc : locs) {
            try {
                Currency currency = Currency.getInstance( loc );

                if ( currency != null ) {
                    toret.add( currency );
                }
            } catch(Exception exc)
            {
                // Locale not found
            }
        }

        return toret;
    }

Hope this helps.
