In Java, is there any way to get a Locale given its display name?

That is, if I have "English (United States)" I'd like to get "en-US", or an appropriate java.util.Locale. It looks like the API is a one-way street, but perhaps I'm not looking in the right place. Thanks in advance.

You could use Apache's commons-lang:

org.apache.commons.lang.LocaleUtils.toLocale(localeStr);

Display name in which language?

Locale[] locales = Locale.getAvailableLocales();
for (Locale current : locales) {
  for (Locale test : locales) {
    System.out
        .print(test.getDisplayName(current) + " ");
  }
  System.out.println();
}

I assume that if you are dealing with locales, you need to handle multiple languages.

No, it does not appear that there is such a method in the API. However, you could create a cache using the Locales returned by Locale.getAvailableLocales(); then you can simply look up the display name in this cache.

private static Map<String, Locale> displayNames = new HashMap<String, Locale>();
static {
    for (Locale l : Locale.getAvailableLocales()) {
        displayNames.put(l.getDisplayName(), l);
    }
}

public static Locale getLocale(String displayName) {
    return displayNames.get(displayName);
}

I did this once and I don't think it's guaranteed to work all the time because the locales could be named differently in each JVM implementation. Loop through the locales until you find the one you want.
