List of usage examples for java.util Locale toString
@Override public final String toString()
Locale object, consisting of language, country, variant, script, and extensions as below: language + "_" + country + "_" + (variant + "_#" | "#") + script + "_" + extensionsLanguage is always lower case, country is always upper case, script is always title case, and extensions are always lower case.
