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

Question

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.

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);
}
