This guide WILL attempt to keep up-to-date with the best commands to run. What's important are the commands, and the general form of the outputs. This guide DOES NOT guarantee or even attempt to keep all those command outputs updated with the ever-evolving Hombrew formulae changes. Our goal IS NOT to keep up with exactly what the output is at the present day. The intent of including these outputs is to illustrate what output should look like. Note that this guide contains plenty of CLI command outputs. We will cover how to install whatever is most readily available.

We favor OpenJDK because it has a permissive license, the GPL v2 with Classpath Exception (aka linking exception). This guide favors free, simple, and permissive licensing whenever possible, so we will favor OpenJDK first, then AdoptOpenJDK if plain OpenJDK isn't available, any other open source distributions, and finally Oracle JDK if no other options are available.

To install an earlier version of the JRE, you must first uninstall the current version. To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. However, the system will not replace the current JRE with a lower version.

Installing the JDK and JRE on macOS is performed on a systemwide basis for all users. You cannot install Java for a single user.
