Get the currency format for a country that does not have a Locale constant
提问by Venkat
I want to get the currency format of India, so I need a Localeobject for India. But there exists only few a countries that have a Localeconstant (a static final Locale), and India is not one of them.
我想获取印度的货币格式，所以我需要一个Locale印度的对象。但是只有少数 a 具有Locale常数 (a static final Locale) 的国家，而印度不是其中之一。
To get the currency symbols for the US and UK, I can do the following:
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());
}
That uses the constants Locale.USand Locale.UK. If i want to get the Indian currency format, what can I do?
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？

According to the JDK release notes, you have locale codes hi_IN(Hindi) and en_IN(English).
根据JDK 发行说明，您有区域设置代码hi_IN（印地语）和en_IN（英语）。
System.out.println(Currency.getInstance(new Locale("hi", "IN")).getSymbol());

看看这个指南：https: //docs.oracle.com/javase/1.5.0/docs/guide/intl/locale.doc.html有hi_IN印地语，印度

Here is an utility method to have the symbol, whatever is your locale
这是一个具有符号的实用方法，无论您的语言环境是什么
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);
}
}

heres is simple thing u can do ,
这是你可以做的简单的事情，
float amount = 100000;
NumberFormat formatter = NumberFormat.getCurrencyInstance(new Locale("en", "IN"));
String moneyString = formatter.format(amount);
System.out.println(moneyString);
The output will be , Rs.100,000.00 .
输出将为 100,000.00 卢比。

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
