Description: This Java tutorial describes how to use NumberFormat to format currencies.
Tutorial created using: Windows XP || JDK 1.5.0_09 || Eclipse Web Tools Platform 2.0 (Eclipse 3.3.0)

To format a number according to a particular currency, we can call NumberFormat.getCurrencyInstance() to get a format object. Calling format() on this object with our number will format our number according to the currency of the default locale. To format a number for a different currency, we can pass the particular desired locale to NumberFormat.getCurrencyInstance(), which will return a format object for that particular currency.

The CurrencyFormatTest class demonstrates formatting a double in US dollars and in Swedish kronor.

package test;

import java.text.NumberFormat;
import java.util.Locale;

public class CurrencyFormatTest {

	public static void main(String[] args) throws Exception {

		double num = 1323.526;

		NumberFormat defaultFormat = NumberFormat.getCurrencyInstance();
		System.out.println("US: " + defaultFormat.format(num));

		Locale swedish = new Locale("sv", "SE");
		NumberFormat swedishFormat = NumberFormat.getCurrencyInstance(swedish);
		System.out.println("Swedish: " + swedishFormat.format(num));



The output of CurrencyFormatTest is shown here:

US: $1,323.53
Swedish: 1 323,53 kr
