    Default Setting what currency i want with getCurrencyInstance()

    Hi all, like in my post title, how do i set an alternative currency to print out.

    For example with the following program it is printing out in £ format. Im guessing this is to do with my Locale and the fact Im in the UK.

    How would i print this out with the dollar sign then? without changing any settings.

    Thanks

     
    // ask user how many quarters, dimes and nickels they have
    // print out how much money the user has, format the output to display currency symbol
     
    import java.util.Scanner;
    import java.text.NumberFormat;
     
    public class usaCurrencyAdd {
     
        public static void main(String[] args) {
     
            final double quarterValue = 0.25;
            final double dimeValue = 0.10;
            final double nickelValue = 0.05;
            int quartersQuantity, dimesQuantity, nickelsQuantity;
            double quartersTotal, dimesTotal, nickelTotal, grandTotal;
     
            Scanner scan = new Scanner(System.in);
     
            System.out.println("How many quarters do you have?");
            quartersQuantity = scan.nextInt();
     
            System.out.println("How many dimes do you have?");
            dimesQuantity = scan.nextInt();
     
            System.out.println("How many nickels do you have?");
            nickelsQuantity = scan.nextInt();
     
            quartersTotal = quarterValue * quartersQuantity;
            dimesTotal = dimeValue * dimesQuantity;
            nickelTotal = nickelValue * nickelsQuantity;
            grandTotal = quartersTotal + dimesTotal + nickelTotal;
     
            NumberFormat fmt = NumberFormat.getCurrencyInstance();
     
            System.out.println(fmt.format(grandTotal));
    }
    }

    Default Re: Setting what currency i want with getCurrencyInstance()

    Two options:

    1. Create your own Currency object based upon a Locale of your choice.
    2. Use DecimalFormat where you can specify the format: "$#.##" or whatever you like.
