Hey,
I’d like to learn Java language with Spring framework for backend - do you know any good learn guides (like P1xt guides) or materials recommended by you? Now I follow Tim Buchalka’s course on Udemy, wich is good but what’s next? Go straight to the spring tutorial?
Learning java stack is a lot more complicated compared to js stack.
I can suggest courses from this website https://www.virtualpairprogrammers.com/ (paid).
They offer more or less reasonable approach from total beginner to someone who groks intermediate java ee / spring.
Also starting with spring boot would be a better choice since it contains “sane” defaults, which you can start customizing on your own when needed.
