To get started with Zulu JDK, download and uncompress it to your board: $ cd /usr/lib/jvm But only Azul seems to have one which is a perfect fit for Raspberry Pi’s with an ARMv6: the Zulu community edition of JDK 11. Luckily there are different suppliers providing ready-made packages of the JDK for multiple platforms. The sources for Java are available as open-source on OpenJDK, which means, if you can’t find the correct version for a specific board, it is possible to compile it yourself.

If you prepared a microSD card with the latest version of Raspbian OS (full version), Java is already installed!
