How to change NumberFormat from especific currency to a dollar currency

Question

I have this block of code

double price = rs.getDouble("price");

NumberFormat nf= NumberFormat.getCurrencyInstance();

String formatedPrice = nf.format(price);

buff.append("( " + formatedPrice + ")");

When I run the code everything works fine but the currency is set to for example: ( C800 ). I guess is because my country has the "Colon" for currency, but that is a thing from the past we now use the Dollar currency. So how can I change the currency to show this: ($400) instead of this (C300). Thanks very much for any help.

Answer 1

Use instead:

NumberFormat nf= NumberFormat.getCurrencyInstance(Locale.US);

Answer 2

Assuming you are using US dollar you can use NumberFormat.getCurrencyInstance(Locale.US)

Answer 3

You can add a locale as parameter to getCurrencyInstance:

NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.US);

Answer 4

You can default it to $

Here is the solution

    double price = rs.getDouble("price");
    NumberFormat nf= NumberFormat.getCurrencyInstance();
    nf.setMaximumFractionDigits(2);
        Currency currency = Currency.getInstance(Locale.US);
        nf.setCurrency(currency);
        String formatedPrice = nf.format(price);
         System.out.println("( " + formatedPrice + ")");

Here is the solution
