Java: Currency symbol based on ISO 4217 currency cod

Question

Below program prints the Currency symbol given the ISO 4217 currency code.

import java.util.*;  public class Currency{      public static void main(String args[]) {         Currency myInstance = Currency.getInstance(args[0]);         System.out.println(myInstance.getSymbol());     } } 

Problem: Works fine when the string USD is input. For other inputs like EUR just return the Currency Code.

Sample input , ouput from the program:

input: java Currency USD  output: $ input: java Currency EUR output: EUR -> I expect the symbol of Euro here 

Answer 1

Currency.getSymbol() returns the currency symbol relative to the default locale.

Gets the symbol of this currency for the default locale. For example, for the US Dollar, the symbol is "$" if the default locale is the US, while for other locales it may be "US$". If no symbol can be determined, the ISO 4217 currency code is returned.

Use Currency.getSymbol(Locale locale) if you want the symbol for a different locale.

System.out.println(    Currency.getInstance("USD").getSymbol(Locale.US) ); // prints $  System.out.println(    Currency.getInstance("USD").getSymbol(Locale.FRANCE) ); // prints USD  System.out.println(    Currency.getInstance("EUR").getSymbol(Locale.US) ); // prints EUR  System.out.println(    Currency.getInstance("EUR").getSymbol(Locale.FRANCE) ); // prints €
