Formatting Negative Currency using the Java.Util Locale

Question

Hi....
I am using the Locale file to get the currency code of a specified country. The code is given below.
public String setCurrency(String _currency){
Locale locale = new Locale("","PG");
NumberFormat format = NumberFormat.getCurrencyInstance(locale);
this.currency = format.format(Double.parseDouble(_currency));
return currency;
When i pass a negative value as the currency (-200) the string which returns will be as (PGK200) and when i pass a positive value it will be as PGK200......
How can i format this so that when i pass a negative value, the returned String will be -PGK200 ??
If there is anyone who knows how i can get this done please reply soon....
Thanks in advance.
Regards
Nuwan.

Check this out:import java.text.DecimalFormat;
import java.text.NumberFormat;
import java.util.Locale;
public class CurrencyEg {
    private String currency;
    public String setCurrency(String _currency){
        Locale locale = new Locale("","PG");
        //NumberFormat format = NumberFormat.getCurrencyInstance(locale);
        DecimalFormat format = (DecimalFormat)NumberFormat.getCurrencyInstance(locale);
        format.setNegativePrefix("-PKG");
        format.setNegativeSuffix("");
        format.setPositivePrefix("PKG");
        format.setPositiveSuffix("");
        format.setMaximumFractionDigits(0);
        this.currency = format.format(Double.parseDouble(_currency));
        return currency;
    public static void main(String args[]) {
        CurrencyEg eg = new CurrencyEg();
        System.out.println("200 -> " + eg.setCurrency("200"));
        System.out.println("-200 -> " + eg.setCurrency("-200"));
}I don't know how valid it is to cast and mess about with the format - but it gives exactly the output you were after:200 -> PKG200
-200 -> -PKG200
