Get system language and use with ResourceBundle

How would I get the system's current language and use that for the ResourceBundle?

Lets say the client's machine is running in Japanese, then I want my application to switch to Japanese, if that language file is not available, it should have a fallback solution.

I know I can use the ResourceBundle, but how would I accomplish the above mentioned setting?

ResourceBundle bundle = ResourceBundle.getBundle("lang", new Locale("jp", "JP"));
Solution

  • The resource bundle automatically tries the system's current language, and then falls back to the default if that doesn't exist (ResourceBundle.getBundle("lang") will search in the following order, presuming that the system language is jp_JP: lang_jp_JP.properties -> land_jp.properties -> lang.properties ). You can look at the process ResourceBundle uses to resolve names here
