I think you're talking about ResourceBundles with the GUI interface labels.

https://docs.oracle.com/javase/tutorial/i18n/resbundle/concept.html

As for the input changing, it's been asked already:

Changing Keyboard Input language in Java

You are talking about implementing internationalization which Java fully supports. This trail covers the details of making your application i18n compliant.

You can do that using ResourceBundles, it loads UI strings on the basis of the locale settings of the application.

You can start with this article on localization...

Not entirely sure what you mean by "stdin" changing to a language though.
