The MagPi step-by-step video
In “The MagPi Magazine” #93 and #94, published by the Raspberry Pi Foundation, you can find two articles which describe how you can get started with Java, Maven, Visual Studio Code and Pi4J on the Raspberry Pi.
To make everything even more clear, I created a step-by-step video on Vimeo which shows everything which is described in those two articles.
