没有获取特定区域设置的货币符号 [英] Not getting currency symbols for specific Locale
问题描述
我正在尝试根据他们的Locale获取货币的符号。但它没有返回符号,而是返回代码。我有一个片段:
I am trying to get the symbols of the currencies based on their Locale. But instead of returning a symbol, it is returning the code. I have a snippet:
import java.util.Currency;
import java.util.Locale;
public class CurrencyFormat
{
public void displayCurrencySymbols()
{
Currency currency = Currency.getInstance(Locale.US);
System.out.println("United States: " + currency.getSymbol());
}
public static void main(String[] args)
{
new CurrencyFormat().displayCurrencySymbols();
}
}
Locale.US 它给出符号 $
但如果我替换
For Locale.US it is giving symbol $
but If I replace
Currency currency = Currency.getInstance(Locale.US);
with
Currency currency = Currency.getInstance(Locale.GERMANY);
然后它代替符号给出国家代码。为什么这样以及我们如何获得这些符号?
Then instead of symbol it is giving the country code. Why is this and how we can get the symbols?
编辑:在看了一些答案后我想清除设置一些特定的默认本地不是解决方案,因为我需要一次显示所有可用的符号。
EDIT : After looking some answer I would like to clear that setting some specific default local is not a solution as I need all the avalaible sign displayed at once.
例如
Locale.setDefault(Locale.UK);
会给我欧元符号但是对于doller它会给代码而不是doller sign($) 。
will give me the euro sign but for doller it will give the code instead of doller sign($).
推荐答案
您好请尝试以下代码
import java.text.NumberFormat;
import java.util.Comparator;
import java.util.Currency;
import java.util.Locale;
import java.util.SortedMap;
import java.util.TreeMap;
public class CurrencyExample
{
public static void main(String[] args)
{
Utils.getCurrencySymbol( Currency.getInstance(Locale.US).getCurrencyCode());
Utils.getCurrencySymbol(Currency.getInstance(Locale.JAPAN).getCurrencyCode());
Utils.getCurrencySymbol(Currency.getInstance(Locale.UK).getCurrencyCode());
Utils.getCurrencySymbol("INR");
}
}
class Utils{
public static SortedMap<Currency, Locale> currencyLocaleMap;
static {
currencyLocaleMap = new TreeMap<Currency, Locale>(new Comparator<Currency>() {
public int compare(Currency c1, Currency c2){
return c1.getCurrencyCode().compareTo(c2.getCurrencyCode());
}
});
for (Locale locale : Locale.getAvailableLocales()) {
try {
Currency currency = Currency.getInstance(locale);
currencyLocaleMap.put(currency, locale);
}catch (Exception e){
}
}
}
public static String getCurrencySymbol(String currencyCode) {
Currency currency = Currency.getInstance(currencyCode);
System.out.println( currencyCode+ ":-" + currency.getSymbol(currencyLocaleMap.get(currency)));
return currency.getSymbol(currencyLocaleMap.get(currency));
}
}
上述程序的输出如下:
USD:-$
JPY:-¥
GBP:-£
INR:-Rs.
