Execute this code to generate the list of enum fields to paste :

 String[] codes = java.util.Locale.getISOLanguages();

 Locale locale = new Locale(isoCode);

This still does not answer the question. I was also looking for a kind of enumerator for this, and did not find anything. Some examples using hashtable here, but represent the same as the built-in get

I would go for a different approach. So I created a script in python to automatically generate the list in Java:

<pre><code>#!/usr/bin/python
f = open("data.txt", 'r')
data = []
cc = {}

for l in f:
 t = l.split('\t')
 cc = { 'code': str(t[0]).strip(), 
 'name': str(t[1]).strip()
 }
 data.append(cc)
f.close()

for c in data:
 print """
/**
 * Defines the &lt;a href="http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2"&gt;ISO_3166-1_alpha-2&lt;/a&gt;

 * &lt;p&gt;
 * This constant holds the value of &lt;b&gt;{@value}&lt;/b&gt;.
 *
 * @since 1.0
 *
 */
 public static final String %(code)s = \"%(code)s\";""" % c
</code></pre>

where the data.txt file is a simple copy&amp;paste from Wikipedia table (just remove all extra lines, making sure you have a country code and country name per line).

Then just place this into your static class:

<pre><code>/**
 * Holds &lt;a href="http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2"&gt;ISO_3166-1_alpha-2&lt;/a&gt;
 * constant values for all countries. 
 *

 * 
 * &lt;/p&gt;
 */
public class CountryCode {

 /**

 * class is only used to access its static properties and/or methods. 
 */
 private CountryCode() { }

If you are already going to rely on Java locale, then I suggest using a simple HashMap instead of creating new classes for countries etc.

Here's how I would use it if I were to rely on the Java Localization only:

<pre><code>private HashMap&lt;String, String&gt; countries = new HashMap&lt;String, String&gt;();
String[] countryCodes = Locale.getISOCountries();

for (String cc : countryCodes) {
 // country name , country code map
 countries.put(new Locale("", cc).getDisplayCountry(), cc.toUpperCase());
}
</code></pre>

After you fill the map, you can get the ISO code from the country name whenever you need it.
Or you can make it a ISO code to Country name map as well, just modify the 'put' method accordingly.
