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

Question

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.

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.

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

Here is my code:

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));
}
}

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 ?

Answer 1

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));

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

Answer 2

The problem in Hackerrank challenge is that there is no UTF-8 encoding. Try to use this:

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 */
    try {
      System.setOut(new PrintStream(new FileOutputStream(FileDescriptor.out), true, "UTF-8"));        
      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));
    } catch (Exception e) {
      System.out.println("HackerRank please fix your test terminal");
    }
  }
}

Answer 3

The Solution will be like this;......

For Indian Ruppe,there is no Currency.. We have to format it using decimalFormatter as given below.

DecimalFormat IndianCurrencyFormat = new DecimalFormat("##,##,###.00");
            NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.US);
            NumberFormat nf1 = NumberFormat.getCurrencyInstance(Locale.CHINA);
            NumberFormat nf2 = NumberFormat.getCurrencyInstance(Locale.FRANCE);
            String us = nf.format(payment);
            String india ="Rs." + IndianCurrencyFormat.format(payment);
            String china =nf1.format(payment);
            String france =nf2.format(payment);
           System.out.println("US: " + us);
        System.out.println("India: " + india);
        System.out.println("China: " + china);
        System.out.println("France: " + france);

Answer 4

My solution just do substring get rid of UTF-8 issue

import java.text.DecimalFormat;
import java.text.NumberFormat;
import java.util.Locale;
/*
 * input 12324.134
 * output
 * US: $12,324.13
 * India: Rs.12,324.13
 * China: ￥12,324.13
 * France: 12 324,13 €
 */
import java.util.Scanner;

public class Solution {

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

        // Write your code here.

        DecimalFormat formatter = new DecimalFormat("###,###.00");
        double roundOff = Math.round(payment * 100) / 100.00;
        String us = NumberFormat.getCurrencyInstance().format(roundOff);
        String india = "Rs." + formatter.format(roundOff);
        String china = NumberFormat.getCurrencyInstance(Locale.CHINA).format(roundOff);
        String france_initial = NumberFormat.getCurrencyInstance(Locale.FRENCH).format(roundOff);
        int len = france_initial.length();
        String france = france_initial.substring(0, len - 1) + " €";
        System.out.println("US: " + us);
        System.out.println("India: " + india);
        System.out.println("China: " + china);
        System.out.println("France: " + france);
    }
}

Answer 5

1. In Case if you need to set symbol for a currency or If you want to customize currency symbol, you can try this.

    Locale indialocal = new Locale("en","India"); NumberFormat india = NumberFormat.getCurrencyInstance(indialocal); DecimalFormatSymbols deciFs = new DecimalFormatSymbols(); deciFs.setCurrencySymbol("Rs."); ((DecimalFormat) india).setDecimalFormatSymbols(deciFs); System.out.println("India: " + india.format(payment));

Answer 6

You can also try this code, because above codes are not working on my laptop. Specially for the symbol of YEN

public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    System.out.print("Input --> ");
    double payment = scanner.nextDouble();
    scanner.close();
    Locale indiaLocale = new Locale("en", "IN");
    NumberFormat u = NumberFormat.getCurrencyInstance(Locale.US);
    NumberFormat i = NumberFormat.getCurrencyInstance(indiaLocale);
    NumberFormat c = NumberFormat.getCurrencyInstance(Locale.SIMPLIFIED_CHINESE);
    NumberFormat f = NumberFormat.getCurrencyInstance(Locale.FRANCE);

    System.out.println("US: " + u.format(payment));
    System.out.println("India: " + i.format(payment));
    System.out.println("China: " + c.format(payment));
    System.out.println("France: " + f.format(payment));


}

In your console -->

Input --> 12324.134

US: $1,232.13

India: ₹1,232.13

China: ¥1,232.13

France: 1 232,13 €

Answer 7

If your solution doesn't work because of yen symbol, try pasting that code, but in Java 7:

import java.io.*;
import java.util.*;
import java.text.NumberFormat;
import java.text.DecimalFormat;



public class Solution {

    public static void main(String[] args) {
        
        Scanner sc = new Scanner(System.in);
        Double number = sc.nextDouble();
        DecimalFormat IndianCurrencyFormat = new DecimalFormat("##,##,###.00");
       
  
        
        String formattedStr = NumberFormat.getCurrencyInstance(Locale.US).format(number);

        System.out.println("US: " + formattedStr);
        System.out.println("India: Rs." + IndianCurrencyFormat.format(number));
        formattedStr = NumberFormat.getCurrencyInstance(Locale.CHINA).format(number);
        System.out.println("China: " + formattedStr);
        formattedStr = NumberFormat.getCurrencyInstance(Locale.FRANCE).format(number);
        System.out.println("France: " + formattedStr);

        
        
        
    }
}

In Java 15 that doesn't work.

Answer 8

Its very some difficult task when working with the numbers to format currencies, By creating local instances through.getCurrencyInstances(new Locale("X", "Y")) meth for CHINA:"zh", "CN" for France: "sk", "SK" required method example:

`import java.util. ; import java.text. ; import java.text.NumberFormat;

public class Solution {

public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    double payment = scanner.nextDouble();
    scanner.close();
    
    // Write your code here.
    
    NumberFormat us1 = NumberFormat.getCurrencyInstance(new Locale("en", "US"));
    String us = us1.format(payment);
    
    NumberFormat india1 = NumberFormat.getCurrencyInstance(new Locale("en", "IN"));
    String india = india1.format(payment);
    
    NumberFormat china1 = NumberFormat.getCurrencyInstance(new Locale("zh", "CN"));
    String china = china1.format(payment);
    
    NumberFormat fr1 = NumberFormat.getCurrencyInstance(new Locale("sk", "SK"));
    String fr = fr1.format(payment);
    
    System.out.println("US: " +us);
    System.out.println("India: " +india);
    System.out.println("China: " +china);
    System.out.println("France: " +fr);
}

}`

This is helpful for HackerRank.

Create local variable because India haven't currency code Refer to this -https://docs.oracle.com/javase/tutorial/i18n/locale/create.html

import java.io.*;
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;
import java.text.NumberFormat;
import java.util.Locale;

public class Solution {
    
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        double payment = scanner.nextDouble();
        scanner.close();
        
       
        
        Locale indiaLocale = new Locale("en", "IN");

        // Write your code here.
        NumberFormat us = NumberFormat.getCurrencyInstance(Locale.US);
        NumberFormat india = NumberFormat.getCurrencyInstance(indiaLocale);
        NumberFormat china = NumberFormat.getCurrencyInstance(Locale.CHINA);
        NumberFormat france = NumberFormat.getCurrencyInstance(Locale.FRANCE);
        
        if(payment>=0 || payment<=Math.pow(10,9)){
            
            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));
        
        }
    }
