Homebrew may also auto-update upon running key homebrew commands such as install or upgrade. Just be aware that if something's been working for a while, the command output might look old, but the command itself will probably still run fine for more recent updates. 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. For versions prior to Java 8 or other special circumstances, OpenJDK may not be available.For Java 8 and later, OpenJDK is readily available.For more information, see Oracle now requires a subscription to use Java SE (2018). 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.
