If you download the .tar.gz for OpenJDK 11 directly from http://jdk.java.net/11/, there’s no obvious installation instructions (at least that I could find) on the OpenJDK website or 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, which composes a number of useful things relating to the JDK that you’re currently using in your PATH. Click 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.

/usr/libexec/java_home: This will show you where the current JDK home is, for example:

For

/usr/libexec/java_home -V: This lists all installed JDKs, which is shown below:


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!

This is a short note about getting started with Java 11 LTS or Java 13 on macOS Catalina. As you probably know, starting with Java 11 there was a big change in the license under which the official Oracle JDK is provided. In short, you need to buy a license from Oracle if you want to use the official JDK in a commercial setting. As far as I know, using Oracle’s JDK on your private computer for testing and learning purposes is allowed.
That being said, for most users OpenJDK is the new JDK of choice, it is provided under an open source license and you don’t need to pay for using it.

There is also a video version of this tutorial:
At this time, Java 11, the long term release or LTS, of Java is no longer supported on the OpenJDK website. You can still get the archived version, but this is not recommended because it doesn’t include any new security patches. If you still need to use Java 11, use an alternative build like the one from AdoptOpenJDK. From the AdoptOpenJDK page you will download a pkg file that you can install on your macOS machine directly by double clicking on it.
After you’ve installed the AdoptOpenJDKpkg file, check if you can use it with:
This is what I see on my machine:
If you prefer to use the Java version provided by the OpenJDK website, you will need to use Java 13. Start by getting OpenJDK, chose the macOS version. Extract the archive by double clicking on the file or, assuming it is in your Downloads folder, write this in your Terminal:
Next step, is to move the extracted folder to a place where macOS searches for Java JDK:
Now, check if you’ve successfully installed the JDK with:
This is what I see on my machine:
Just to be sure that everything works, try to compile and run a simple program:
Save the above as HelloWorld.java and compile it with:
If you want to run the compiled version:
This is what I see on my machine:
Side note, you can also run directly the program, without the separate compilation step with:
but this is usually slower than compiling the code with javac and running the compiled code.
