Recently I made a little tax calculation proggy.

Unfortunately; I am unable to discover how to format the results into currency.

My code looks like this

import javax.swing.*; //imports java swing to implement msgbox
public class GetTax //creates class GetTax
{
public static void main (String[] args) //beginning of code
{
String result, output;
double tax, rate;

result = JOptionPane.showInputDialog("Enter the amount of the bill:");
//input msgbox. input for amount of bill.

tax = Double.parseDouble(result);
rate = .06 * tax; //calculate .06 * defined input

//display the calculated results
output = "The sales tax for " + tax + " is " + rate;
JOptionPane.showMessageDialog(null, output, "Tax Calculator",
JOptionPane.INFORMATION_MESSAGE);
System.exit(0);
}
}




If anyone can offer suggestions as to how to format the output into currency i'd be very interested.

thanks

Here's a solution :

NumberFormat nf = NumberFormat.getPercentInstance(Locale.getDefault()); // add this line to your code
....
output = "The sales tax for " + tax + " is " + nf.format(rate);        // adapt the result to display
...

Edit :

Also, if you want to get the default currency of your computer, just add this command :

String currency = Currency.getInstance(Locale.getDefault()).getCurrencyCode();

Normally, the string currency will normally contain EUR if your computer is configured according to the settings of your country.
