Format negative amount of USD with a minus sign, not brackets (Java)

Question

How do I get NumberFormat.getCurrencyInstance() to print negative USD currency values with a minus sign?

Answer 1

Since I faced this problem again, I did some research and found a more resilient solution provided by an ICU:

NumberFormatter
  .withLocale(...)
  .unit(Currency.getInstance("USD"))
  .sign(SignDisplay.AUTO) // "123", "0", and "-123"
  .format(123)
  .toString();

Check API documentation of NumberFormatter for more details.
