2. Apache Commons has LocaleUtils to help parse a string representation. This will return en_US

   String str = "en-US";
   Locale locale =  LocaleUtils.toLocale(str);
   System.out.println(locale.toString());
   

3. You can also use locale constructors.

   // Construct a locale from a language code.(eg: en)
   new Locale(String language)
   // Construct a locale from language and country.(eg: en and US)
   new Locale(String language, String country)
   // Construct a locale from language, country and variant.
   new Locale(String language, String country, String variant)
