If you download the .tar.gz for OpenJDK 11 direct from http://jdk.java.net/11/, there’s no obvious install instructions (at least that I can find) either on the OpenJDK website on in the .gz file. If you’ve done any fiddling with different JDK versions on MacOS before, you’ve probably come across the ‘/usr/libexec/java_home’ utility (see here for my previous article about this utility, and answers to this StackOverflow post which includes one of the most extensive and useful guides to running different JDK versions on MacOS that I’ve seen) which does a number of useful things relating to which JDK you’re currently using in your PATH:

This tutorial demonstrates how to download and install the OpenJDK 11 onto your MacOS devices, providing useful instructions and sample code to get you started. Java, jdk 11, mac os, tutorial. Older releases, which do not include the most up to date security vulnerability fixes and are no longer recommended for use in production, remain available in the OpenJDK Archive.

Refer to below 3. Version switching.
/usr/libexec/java_home : shows you were the current JDK home is, eg:
/usr/libexec/java_home -V : lists all installed JDKs, e.g.:

To switch between JDKs, use /usr/libexec/java_home -v version (e.g. 10):
Knowing that your available JDKs are installed to /Library/Java/JavaVirtualMachines/ by default, moving the contents of the downloaded OpenJDK 11 dir from inside the .gz file to the same location would make sense.
Once you’ve moved it there, java_home -V now shows the new JDK in place:
Updating my aliases to quickly switch versions in my .bash_profile, I now have:
Sourcing the .bash_profile (source .bash_profile) and then running each alias, now I’ve got OpenJDK 11 set up and ready to go!
