I'm a few chapters away from finishing the book I'm using to learn Java programming. And I am not sure where to go once I've read the last page. I've looked for somethings online, found some free books, some tutorials(video and text); about the same things in my book. I'd like to improve, test, and build what I know; but I don't know how or where to start. Keeping it short, I've quite confused with what's next?
