java中特定货币的货币符号位置

我好像没有加载太多的区域设置。。。但法国使用尾随符号,台湾使用前导符号。

public class MyCurrency {
    public static void main(String[] args) {
        System.out.println(format(Locale.FRANCE, 1234.56f));
        System.out.println(format(Locale.TAIWAN, 1234.56f));
    }

    public static String format(Locale locale, Float value) {
        NumberFormat cfLocal = NumberFormat.getCurrencyInstance(locale);
        return cfLocal.format(value);
    }
}

现在,如果您真的想知道货币符号是在开头还是结尾,请使用以下作为起点。注意 bPre

public String format(Locale locale, Float value) {

    String sCurSymbol = "";
    boolean bPre = true;
    int ndx = 0;

    NumberFormat cfLocal = NumberFormat.getCurrencyInstance(locale);
    if (cfLocal instanceof DecimalFormat) { // determine if symbol is prefix or suffix
        DecimalFormatSymbols dfs =
                ((DecimalFormat) cfLocal).getDecimalFormatSymbols();
        sCurSymbol = dfs.getCurrencySymbol();
        String sLP = ((DecimalFormat) cfLocal).toLocalizedPattern();


        // here's how we tell where the symbol goes.
        ndx = sLP.indexOf('\u00A4');  // currency sign

        if (ndx > 0) {
            bPre = false;
        } else {
            bPre = true;
        }

        return cfLocal.format(value);

    }
    return "???";
}

NumberFormat

“CLDR”命名表示基础语言环境数据取自 http://cldr.unicode.org/

// Taken from sun.util.locale.provider.NumberFormatProviderImpl

// Configuration .java files are stored within the JDK's src.zip under directory:
// jdk.localedata/sun/text/resources/cldr/ext
// Look for the "NumberPatterns" key and see the position of \u00a4 (currency symbol)

import sun.util.locale.provider.CalendarDataUtility
import sun.util.locale.provider.LocaleProviderAdapter

locale = Locale.ENGLISH
type = LocaleProviderAdapter.Type.CLDR

Locale override = locale.getUnicodeLocaleType("nu") == null ?
        CalendarDataUtility.findRegionOverride(locale) :
        locale;

LocaleProviderAdapter adapter = LocaleProviderAdapter.forType(type);
String[] numberPatterns = adapter.getLocaleResources(override).getNumberPatterns();

print(numberPatterns[1])
