How to handle language pack

Hi guys,
in the game that I am developing I need to have things like item descriptions, spell tooltips etc I don’t know how to handle these texts.
I gues it is a bad idea to save them as static string in the various classes, isn’t it? :frowning:
Maybe I should have a different jar containing only these texts (I guess it is also useful to implement different language packs)
Who can help me? ???
