Overview

This document outlines the process of quickly installing Java on a Mac. Since I frequently use Java for work and have tried various installation methods, I personally find using SDKMan the most convenient, especially considering future version management. So, in this instance, I will also use SDKMan.

My environment

Installing SDKMan

As shown below:

https://sdkman.io/install

$ curl -s "https://get.sdkman.io" | bash
$ source .zshrc
$ sdk version
SDKMAN!
script: 5.18.2
native: 0.4.2

Installing Java

Relevant commands can be found here:

https://sdkman.io/usage

Check the list of installable Java versions:

$ sdk list java

...

Despite various options, as of August 2023, it's advisable to go with the latest LTS (Long Term Support) version, which is 17, and select Adoptium (Temurin).

$ sdk install java 17.0.8-tem
$ java -version
openjdk version "17.0.8" 2023-07-18
OpenJDK Runtime Environment Temurin-17.0.8+7 (build 17.0.8+7)
OpenJDK 64-Bit Server VM Temurin-17.0.8+7 (build 17.0.8+7, mixed mode)
$ echo $JAVA_HOME
/Users/tkugimot/.sdkman/candidates/java/current

That's all! Thank you very much for your hard work!
