Since OS X 10.7 Java is not (pre-)installed anymore, let’s fix that. As I’m writing this, Java 11.0.4 is the latest version and AdoptOpenJDK is one of the best places to find Prebuilt OpenJDK Binaries. Easy to follow details about how to install OpenJDK are available here.

However, the easiest way is to select OpenJDK 11 (LTS), the HotSpot JVM, and macOS x64, which will expose two option like these:
Clicking on “Install JDK installer”, will download the OpenJDK installer package, e.g. OpenJDK11U-jdk_x64_mac_hotspot_11.0.4_11.pkg, which when executed, will install into this location: /Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk

Almost done. After opening a terminal, the successful installation of the JDK can be confirmed like so:

… hopefully showing something like this:

JAVA_HOME is an important environment variable and it’s important to get it right. Here is a trick that allows me to keep the environment variable current, even after a Java Update was installed. In ~/.zshrc, I set the variable like so:

In previous macOS versions, this was done in ~/.bash_profile. Now it’s done.
