I was curious because I really want to make some 8-bit games and I want to know if java can do that just as good or better than others such as c++. A great example of a good 8-bit game I want to make is http://wootfu.com/beacon/
Forgive my ignorance, but what exactly do you mean by an "8-bit game"? Is that just a game that's similar to those that were available in the era of 8-bit computers?
Or maybe you're programming for a phone or something that only has 8-bit registers?
It's not any of my business, but I'm curious.
