How To Install Different JDK Versions on MacOS with Homebrew

Keywords: Java, JDK (Java Development Kit), MacOS, Homebrew

This how-to guide covers how to install different versions of the JDK on MacOS with Homebrew.

This guide favors OpenJDK

This guide favors free, simple, and permissive licensing whenever possible, so we will favor OpenJDK over Oracle JDK because OpenJDK is licensed GNU GPL with a linking exception. For more information, see Oracle now requires a subscription to use Java SE (2018).

  • For Java 8 and later, we will install OpenJDK.
