I'm looking for a bit of advice.
I'm migrating from an old machine to a new one and I had a huge mess with Java versions in the old one.
Some were installed using Homebrew, some using the .pkg files from Oracle, some using OpenJDK.
What would be the optimal and cleanest way to install Java (like Java SE 13, or the JDK), and maybe an older version for compatibility (say Java 8) on MacOS?
Thanks.

Well, I suppose brew cask install java will do the trick, and install the latest OpenJDK, and also take care of removing old versions when upgrading to newer versions. If you grab the Oracle JDK 8 (AFAIK, no longer publicly available) then you can install that particular version via the *.pkg installer, but over time you will end up with multiple JDKs if you keep doing this for every release.
