Question

我想获得印度的货币格式，所以我需要印度的Locale对象。但是只存在少数Locale常数（static final Locale），而印度不是其中之一的国家。

要获取美国和英国的货币符号，我可以执行以下操作：

public void displayCurrencySymbols() {

    Currency currency = Currency.getInstance(Locale.US);
    System.out.println("United States: " + currency.getSymbol());

    currency = Currency.getInstance(Locale.UK);
    System.out.println("United Kingdom: " + currency.getSymbol());

}

使用常量Locale.US和Locale.UK。如果我想获得印度货币格式，我该怎么办？

Answer 1

根据JDK release notes，您有区域代码hi_IN（印地语）和en_IN（英语）。

System.out.println(Currency.getInstance(new Locale("hi", "IN")).getSymbol());

Answer 2

继承人你可以做的很简单，

  float amount = 100000;

  NumberFormat formatter = NumberFormat.getCurrencyInstance(new Locale("en", "IN"));

  String moneyString = formatter.format(amount);

  System.out.println(moneyString);

输出为，Rs.100,000.00。

这是一个实用的方法来获得符号，无论你的语言环境是什么

    public class Utils {

        public static SortedMap<Currency, Locale> currencyLocaleMap;

        static {
            currencyLocaleMap = new TreeMap<Currency, Locale>(new Comparator<Currency>() {
                @Override
                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);
            return currency.getSymbol(currencyLocaleMap.get(currency));
        }

       public static String  getAmountAsFormattedString(Double amount, Double decimals, String currencyCode) {
            Currency currency = Currency.getInstance(currencyCode);
            double doubleBalance = 0.00;
            if (amount != null) {
                doubleBalance = ((Double) amount) / (Math.pow(10.0, decimals));
            }
            NumberFormat numberFormat = NumberFormat.getCurrencyInstance(currencyLocaleMap.get(currency));
            return numberFormat.format(doubleBalance);
    }


    }

请查看本指南：https://docs.oracle.com/javase/1.5.0/docs/guide/intl/locale.doc.html，印地语，印度有hi_IN

Answer 5

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

double dbValue = 1_23_23_213.89;
Locale lcl = new Locale("hi","IN");
NumberFormat inFrmt = NumberFormat.getNumberInstance(lcl);
System.out.println(inFrmt.format(dbValue));      //12,323,213.89

NumberFormat cur = NumberFormat.getCurrencyInstance(lcl);
System.out.println(cur.format(dbValue));      // ₹12,323,213.89

Answer 6

我们必须手动为印度创建语言环境

Locale IND = new Locale("en", "IN");
NumberFormat india  = NumberFormat.getCurrencyInstance(IND);
int money = 3456
System.out.print(india.format(money));

输出-Rs。 3,456
