[1475]Print currency in a locale-specific format
By Sandy on 2005/07/08 08:47:39 Rate
The getCurrency ( ) method returns a java.util.Currency object.
You can print it directly using System.out.println ( ) , as the toString ( ) method in java.util.Currency is overridden to return the Currency Code ( USD,.... ) .
If your current Locale is US, the following code will print " USD ".
import java.text.NumberFormat;
import java.util.Currency;
public class CurrencyClass
{
public static void main ( String args [ ] )
{
NumberFormat formatter = NumberFormat.getInstance ( ) ;
System.out.println ( formatter.getCurrency ( ) ) ;
}
}
