Install OpenJDK 8 on Mac using brew (AdoptopenJDK)

In this tutorial, I will show you how to install OpenJDK 8 Mac. You have to pay for Oracle JDK so it’s better to use OpenJDK.

OpenJDK (Open Java Development Kit) is a free and open-source implementation of the Java Platform, Standard Edition (Java SE).[1] It is the result of an effort Sun Microsystems began in 2006. The implementation is licensed under the GNU General Public License (GNU GPL) version 2 with a linking exception. Were it not for the GPL linking exception, components that linked to the Java class library would be subject to the terms of the GPL license.
