Console games are just applications like any other PC game. They access hardware by communicating with OS services. The only difference is in consoles you exactly know your hardware and you can make better use of it and OS provides less than a full blown PC OS. But this is not related to Java vs C++ debate. Java is capable of accessing hardware directly. There is even some hardware that directly runs Java or some low-end embedded systems running Java. As of XNU, it is mostly pure C. There are a few C++ files there but they are very far from what we call "modern C++". No templates, no use of standard library, no exceptions, const char* everywhere. Just C with classes.
