The illegal access error message (jdk11+) can be solved by using the [jogl-2.4.0-rc.jars](https://discourse.processing.org/t/processing-in-style-with-java-11/13776/30) as processing-4.0 does. However none of this stuff is suitable for novice programmer. If you can hack python then you can install [py5](https://github.com/hx2A/py5) on RaspberryPI4 as I have done (but that is still at development stage). I am biased as the developer of [PiCrate](https://ruby-processing.github.io/) but that requires a JRuby installation, which is easiest done on the ManjaroArm distro.
