                                       Locale localeToMatch)

findClosestLocale

public static Locale findClosestLocale(Set<Locale> locales,
                                       Locale localeToMatch,
                                       Locale defaultLocale)

getSimpleLocale

public static Locale getSimpleLocale(String languageString)

Parse the given languageString (e.g., "en-us", "en-US", "en_us", "en_US") and create a Locale from it. Parse but then ignore script, variants, extensions and private use. Keep only the language and region. This should not be needed in Java 1.7, which has Locale.forLangaugeTag(languageString), which does the same thing only better.

Parameters:

languageString - - BCP47 or Java language string ("en", "en-us", "en_US", etc.)

Returns:

Locale for that language.
