There are a lot of people who want to switch to Java, but don’t know where to start! In fact, learning Java is not difficult, as long as the development of a good learning route, follow their own plan step by step to do there is no problem!

But this is also very difficult for the novice white first step, because I do not know how to develop their own learning route, so, today this learning route you must seriously look, this is my summary of 2021 the latest learning route, novice white can be assured to learn!
