Loaded into a Select component a json

Hi all, I need some help. Is it possible to load into the “Select” component a list of string contained in a json? (These are nations with any regions). I don’t quite understand how I can convert a json to Java so that I can then load the various nations into the select, and then upon selection, load the eventual regions into another select. Thank you and I hope you can help me
