Using the code below you can get a list of country names and its ISO code by using the locale class implementation in Java.
package org.kodejava.util;
import java.text.Collator;
import java.util.*;
public class CountryList {
public static void main(String[] args) {
// A collection to store our country object
List<Country> countries = new ArrayList<>();
// Get ISO countries, create Country object and
// store in the collection.
String[] isoCountries = Locale.getISOCountries();
for (String country : isoCountries) {
Locale locale = new Locale("en", country);
String iso = locale.getISO3Country();
String code = locale.getCountry();
String name = locale.getDisplayCountry();
if (!"".equals(iso) && !"".equals(code) && !"".equals(name)) {
countries.add(new Country(iso, code, name));
}
}
// Sort the country by their name and then display the content
// of countries collection object.
countries.sort(new CountryComparator());
for (Country country : countries) {
System.out.println(country);
}
}
/**
* Country pojo class.
*/
static class Country {
private final String iso;
private final String code;
private final String name;
Country(String iso, String code, String name) {
this.iso = iso;
this.code = code;
this.name = name;
}
public String toString() {
return iso + " - " + code + " - " + name.toUpperCase();
}
}
/**
* CountryComparator class.
*/
private static class CountryComparator implements Comparator<Country> {
private final Comparator<Object> comparator;
CountryComparator() {
comparator = Collator.getInstance();
}
public int compare(Country c1, Country c2) {
return comparator.compare(c1.name, c2.name);
}
}
}
