Installing Java and JavaFX on the Raspberry Pi

A guide to installing Java 11 and JavaFX on Raspberry Pi (ARMv7/ARMv8 models). While Raspberry Pi OS ships with OpenJDK 11 by default, JavaFX requires the LibericaJDK from BellSoft, which bundles JavaFX support for ARM processors. The post covers downloading and installing LibericaJDK via apt, switching between Java versions using update-alternatives, and points to install scripts on GitHub from the author's book 'Getting started with Java on Raspberry Pi'.
