jar没有为java 7中的几个货币代码获取货币符号和语言环境代码

Question

无法获取Java 7中少数货币代码的货币符号和区域设置代码。例如：货币代码

AFN,
AMD,
ANG,
AOA,
AUD,
AWG,
AZN, etc..

并尝试用DecimalFormat.getAvailableLocales()代替NumberFormat.getAvailableLocales()但没有用

以下是获取货币符号的代码

package com.test.testandbackups;

import java.text.NumberFormat;
import java.util.Currency;
import java.util.Locale;

public class CurrencyUtils {

    public static void main(String args[]) throws Exception {
        String currencyCode = "INR";
        String ss = currencySymbol(currencyCode);

        System.out.println(ss);

    }

    public static String currencySymbol(String currencyCode) {
        String currencySymbol = null;
        currencySymbol = Currency.getInstance(currencyCode).getSymbol(
                getLocale(currencyCode));
        return currencySymbol;
    }

    private static Locale getLocale(String currencyCode) {
        for (Locale locale : NumberFormat.getAvailableLocales()) {
            String code = NumberFormat.getCurrencyInstance(locale)
                    .getCurrency().getCurrencyCode();
            if (currencyCode.equals(code)) {
                return locale;
            }
        }
        return null;
    }

}
