Or switch to 17 for the current terminal session: sdk use java 17-open Make Java 17 the default version: sdk default java 17-open Install one of those versions, for example, Java 17 LTS: sdk install java 17-open List the Java versions available to make sure you know the version ID sdk list java SDKMAN allows setting a global default version, and a version specific to the current shell. SDKMAN also places the installed JDK's into its own directory tree, which is typically ~/.sdkman/candidates/java. SDKMAN is a bit different and handles both the install and the switching. Installing and Switching versions with SDKMAN

These two primary options are described here. However, there are easier options such as SDKMAN and asdf that also will install other important and common tools for the JVM. The advantage of a manual install is that the location of the JDK can be placed in a standardized location for Mac OSX. You can install Java using whatever method you prefer including SDKMAN, asdf, Homebrew, or a manual install of the tar.gz file. TL DR - Preferred Methods of Installation Switching can be done by SDKMAN, asdf, or manually by setting JAVA_HOME. Installation can be done by Homebrew, SDKMAN, asdf, or a manual install. You have a few options for how to do the installation as well as manage JDK switching. Easily work with Java 7, Java 8, Java 9, Java 10, Java 11, Java 12, Java 13, Java 14, Java 15, Java 16, Java 17, Java 18, and the latest Java 19! This includes alternative JDK's from OpenJDK, Oracle, IBM, Azul, Amazon Correto, Graal and more. The system will not install a JRE that has an earlier version than the current version.Note: These solutions work for various versions of Java including Java 8 through Java 17 (the LTS version) and Java 18.

When you install the JRE, you can install only one JRE on your system at a time. 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. When you install the JDK, it also installs the JRE. Administrator privileges are required to install the JDK and JRE on macOS. Installing the JDK and JRE on macOS is performed on a systemwide basis for all users. You cannot install Java for a single user. The following are the system requirements for installing the JDK and the JRE on macOS:
