NumberFormat.getCurrencyInstance()不返回语言环境中国和法国的货币符号(jdk-1.8)

问题描述

我编写了一个程序，以返回带有某些国家/地区的货币符号的双精度值.为此，我正在使用getCurrencyInstance()方法来获取特定国家/地区的符号.

I have written a program to return double values with the currency symbols of some countries. For this I am using getCurrencyInstance() method to get symbol of particular country.

该问题特定于笔记本电脑的 JDK-1.8 ，并且可以在联机编译器上正常运行.我面临的问题是 CHINA 和 FRANCE 的货币符号用'?'表示.但是对于 INDIA 和 US ，会显示正确的符号.

The problem is specific to my laptop's JDK-1.8 and works fine on online compiler.The problem, I am facing is that the currency symbol for CHINA and FRANCE are represented with '?'. But for INDIA and US, correct symbols are shown.

我现在正在解决这个问题.因此，任何线索都将有所帮助.

I am working on this problem for a bit now. Hence, any leads would be helpful.

这是我的代码:

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

public class Solution {

public static void main(String[] args) {
    /* Read input */
    Scanner scanner = new Scanner(System.in);
    double payment = scanner.nextDouble();
    scanner.close();

    /* Create custom Locale for India.
    Locale indiaLocale = new Locale("en", "IN");

    /* Create NumberFormats using Locales */
    NumberFormat us     = NumberFormat.getCurrencyInstance(Locale.US);
    NumberFormat india  = NumberFormat.getCurrencyInstance(indiaLocale);
    NumberFormat china  = NumberFormat.getCurrencyInstance(Locale.CHINA);
    NumberFormat france = NumberFormat.getCurrencyInstance(Locale.FRANCE);

    /* Print output */        
    System.out.println("US: "     + us.format(payment));
    System.out.println("India: "  + india.format(payment));
    System.out.println("China: "  + china.format(payment));
    System.out.println("France: " + france.format(payment));
}
}

我的机器上的相应输出是:

The corresponding output on my machine is:

12324.134
US: $12,324.13
India: Rs.12,324.13
China: ?12,324.13
France: 12 324,13 ?

推荐答案

在中国使用此代码.Numberformat类的getCurrency().getSymbol(locale)将返回特定区域的货币符号. System.out.println("China: " + china.getCurrency().getSymbol(Locale.CHINA) + china.format(payment));

for china use this code.Numberformat class's getCurrency().getSymbol(locale) will return currency symbol for particular region. System.out.println("China: " + china.getCurrency().getSymbol(Locale.CHINA) + china.format(payment));

在法国使用此System.out.println("France: " + france.format(payment) + " " + france.getCurrency().getSymbol(Locale.FRANCE));

For France use thisSystem.out.println("France: " + france.format(payment) + " " + france.getCurrency().getSymbol(Locale.FRANCE));
