In this article, we show you how to use the Locale class to play around the list of countries.

1. List of Countries and its code

The Locale.getISOCountries()will return a list of all 2-letter country codes defined in ISO 3166.

package com.simplecode.net;

import java.util.Locale;

public class Country {

	public static void main(String[] args) {

		Country obj = new Country();
		obj.country();

	}

	public void country() {

		String[] locales = Locale.getISOCountries();

		for (String countryCode : locales) {

			Locale obj = new Locale("", countryCode);

			System.out.println("Country Code = " + obj.getCountry()
					+ ", Country Name = " + obj.getDisplayCountry());

		}
	}

}
