During the install it asked me to symblink ( sudo ln -sfn /usr/local/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk). Here I installed OpenJDK 18 using Homebrew. Lrwxr-xr-x 1 root wheel 42 Apr 3 09:30 openjdk.jdk -> /usr/local/opt/openjdk/libexec/openjdk.jdkĭrwxr-xr-x 3 root wheel 96 Jan 20 13:22 temurin-17.jdk $ ls -l /Library/Java/JavaVirtualMachinesĭrwxr-xr-x 3 root wheel 96 adoptopenjdk-11.jdkĭrwxr-xr-x 3 root wheel 96 adoptopenjdk-15.jdkĭrwxr-xr-x 3 root wheel 96 jdk1.8.0_151.jdk usr/local/Cellar/openjdk/18/libexec/openjdk.jdk/Contents/Home Here is two output which you can understand thisġ8 (x86_64) 'Homebrew' - 'OpenJDK 18' /usr/local/Cellar/openjdk/18/libexec/openjdk.jdk/Contents/Homeġ7.0.2 (x86_64) 'Eclipse Temurin' - 'Eclipse Temurin 17' /Library/Java/JavaVirtualMachines/temurin-17.jdk/Contents/Homeġ5.0.1 (x86_64) 'AdoptOpenJDK' - 'AdoptOpenJDK 15' /Library/Java/JavaVirtualMachines/adoptopenjdk-15.jdk/Contents/Homeġ1.0.5 (x86_64) 'AdoptOpenJDK' - 'AdoptOpenJDK 11' /Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Homeġ.8.181.13 (x86_64) 'Oracle Corporation' - 'Java' /Library/Internet Plug-Ins/ugin/Contents/Homeġ.8.0_151 (x86_64) 'Oracle Corporation' - 'Java SE 8' /Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home If we are using any other approach, installation recommends us to create symlink to this folder if it installs in other directory. Mac places the Java Virtual Machines under /Library/Java/JavaVirtualMachines folder when installing as mac application. So I decided to use it for JDK install as well. I use brew to install all development related tools/library/kit. For Windows, installer executable, for linux yum/rpm packages, for mac app package. Which usually download the package from the JDK vendor and installing with user interface. Most prefered/recommended way is the operating system way for end user/developer. Here are few ways I know of installing JDK

It is recommended to choose an approach and stick with it while installing multiple version. We can also download the compressed content and extract. In all those installations JDK contents extracted into a directory which makes more sense for the operating system. Multiple implementors of JDK gives multiple options to instlall JDK for each operating system.
