What language to use to develop a code handling Controllers ?

Question

I'd like to create a game which could be played by 2 persons on the same Computer, and there are too many keys used to play both on the same keyboard. Therefore I need my code to handle a Controller.
Is it possible with Java ? C++ ? P5.JS ? Else ?

Answer 1

if you develop you game with platforms like unity you can do it mainly using c# python etc

I think Java is not good for your purpose, once it runs in a virtual machine nevertheless c++ can help you
