Learn a Java game library

Hello! Im have been learning java for some time now and want to develop some 2d desktop games (on my mac) using either libgdx or lwjgl. I cant find any comprehensice courses or books on these topics. Any suggestions?

Also: Wrong subforum. This for when you want to write a tutorial/article.

I’ve read this book, it’s a great book to start learning how to build 2D games step by step and initiate a 3D game prototype.
