How to install Java 8 on Mac

Question

I want to do some programming with the latest JavaFX  which requires Java 8  I m using IntelliJ 13 CE and Mac OS X 9 Mavericks  I ran Oracle s Java 8 installer  and the files look like they ended up at    Library Java JavaVirtualMachines jdk1 8 0 05 jdk   but previous versions are at    System Library Java JavaFrameworks jdk1 6       Not sure why the latest installer puts this in  Library instead of  System Library  nor what the difference is   But  usr libexec java home doesn t find 1 8  so all the posts I ve found on how to set your current java version don t work  I ve tried adding a symbolic link to make it look like 1 8 is in the  System Library    path  but it doesn t help   usr libexec java home -V still only lists the old Java 1 6   Ironically  the  Java  control panel under System Preferences shows only Java 1 8   Why doesn t Oracle s installer put it where it really goes  And how can I work around this problem

Oracle has a poor record for making it easy to install and configure Java  but using Homebrew  the latest OpenJDK  Java 14  can be installed with  brew install --cask adoptopenjdk8  For the many use cases depending on an older version  commonly Java 8   the AdoptOpenJDK project makes it possible with an extra step  brew tap adoptopenjdk openjdk brew install --cask adoptopenjdk8  Existing users of Homebrew may encounter Error  Cask adoptopenjdk8 exists in multiple taps due to prior workarounds with different instructions  This can be solved by fully specifying the location with brew cask install adoptopenjdk openjdk adoptopenjdk8

An option that I am starting to really like for running applications on my local computer is to use Docker  You can simply run your application within the official JDK container - meaning that you don t have to worry about getting everything set up on your local machine  or worry about running multiple different versions of the JDK for different apps etc   Although this might not help you with your current installation issues  it is a solution which means you can side-step the minefield of issues related with trying to get Java running correctly on your dev machine   The benefits are    No need to set up any version of Java on your local machine  you ll just run Java within a container which you pull from Docker Hub  Very easy to switch to different versions of Java by simply changing the tag on the container  Project dependencies are installed within the container - so if you mess up your config you can simply nuke the container and start again      A very simple example    Create a Dockerfile   FROM java 8 COPY    usr src myapp WORKDIR  usr src myapp    Here we are specifying the Java container running version 8 of the SDK  java 8 - to use Java 7  you could just specify  java 7   We are mapping the local directory with the directory   usr src myapp inside the container   Create a docker-compose yml file   version   2   services    java      build        volumes        -    usr src myapp   Now  assume we have this Java file    HelloWorld java  public class HelloWorld       public static void main String   args                    System out println  Hello  World              So we have the following file structure        Dockerfile    docker-compose yml    HelloWorld java   You can do various Java things like   compile   docker-compose run --rm java javac HelloWorld java     You should note that the HelloWorld class shows up in your current directory  this is cause we ve mapped the current directory to the location inside the container where our code exists   run   docker-compose run --rm java java HelloWorld     Note  the first time you run this it will fetch the image etc  This will take a while - it only happens the first time docker-compose run - runs a command from within the container -rm tells docker to remove the container once the command is finished running java is the name of the service container  from our docker-compose file  against which this command will run the rest of the line is the command to run inside the container    This is quite a cool way of dealing with running different versions of Java for different apps without making a complete mess of your local setup      Here is a slightly more complex example which has Maven and a simple Spring app  Disclaimer    I haven t really tried this within an IDE like IntelliJ - so not entirely sure how that aspect of things would work  Though it looks like docker support is coming Here is a significantly more complex example running Microservices with Spring Boot  Zuul and Docker

tl dr  Library Java JavaVirtualMachines  is the correct location for the JVM to be installed  This has been the case for several years now  Many years ago  other locations were used  but no longer  You have a choice of several vendors to obtain an installer app to install a Java implementation on your Mac  Download an installer to run locally and then discard  as you commonly do for many apps  Your Question mentions JavaFX OpenJFX  You might find it convenient to use a Java implementation that comes bundled with the OpenJFX libraries  such as LibericaFX from BellSoft or ZuluFX from Azul Systems  Use the Installer  Luke Other answers suggesting the Homebrew package manager seem a bit extreme to me  I am sure Homebrew has some good uses  But to simply run Java  or do Java programming  installing Homebrew is a needless extra step  Installing Homebrew  package manager  for the single goal of obtaining Java is like building a landing strip to park your car instead of using your driveway  If you already have it  fine  use it  But suggesting Homebrew to those who simply need Java is poor advice  People not already using Home-brew can simply download a Mac installer from a trusted source  You have multiple sources to obtain an easy-to-use installer app to put Java on your Mac  Run the installer on your Mac just as you do for many other apps  Here is a flowchart diagram for finding a source of Java 11  some of which also offer Java 8   Download an installer from a vendor such as Adoptium AdoptOpenJDK net    Run the installer   JavaVirtualMachines folder is now correct  Why doesn t Oracle s installer put it where it really goes  And how can I work around this problem   Not a problem  The folder  Library Java JavaVirtualMachines  is the new home for JVMs on macOS   To install a JVM  use an installer  discussed below  To uninstall  simply use the Finder to delete a JVM from that folder  You will be prompted for system admin password to complete the removal   Java 9  amp  10  amp  11 Back in 2010  Apple joined the OpenJDK project  along with Oracle  IBM  Red Hat  Azul  and other Java vendors  Each member contributes source code  testing  and feedback to the unified OpenJDK codebase  Apple contributed most of its Mac-specific code for its JVM  Now Apple no longer releases its own Mac-specific JVM  You now have your choice of JVM supplier  with builds coming from the OpenJDK codebase  You will find source code at  http   openjdk java net New release cadence Be aware that in 2017  Oracle  the JCP  and OpenJDK have adopted a new rapid    release train    plan for regularly-scheduled versions of Java to be delivered in a predictable manner  Read this 2018-07 Azul Systems blog post for many details  Eliminating Java Update Confusion by Simon Ritter  Also read Java Is Still Free  Vendors For a rather exhaustive list of past and present JVM implementations  see this page at Wikipedia  Here is a discussion of a few vendors  See the flowchart above for more vendors Oracle JDK Oracle provides JDK and JRE installers for multiple platforms including macOS  Over the years since acquiring Sun  Oracle has combined the best parts of the two JVM engines  HotSpot and JRocket  and merged them into the OpenJDK project used as the basis for their own branded implementations of Java  Their new business plan  as of 2018  is to provide a Oracle-branded implementation of Java for a fee in production  and at no cost for use in development testing demo  Support for previous releases requires a paid support program  They have declared their intention for their branded release to be at feature-parity with the OpenJDK release  They have even donated their commercial add-ons such as Flight Recorder to the OpenJDK project  Oracle also releases a build of OpenJDK with no support  http   jdk java net  Oracle has produced a special purpose JDK  GraalVM  Zulu  amp  Zing by Azul Azul Systems provides a variety of JVM products   Their Zulu line is based directly on OpenJDK  and is available at no cost with optional paid support plans  Their Zing line offers commercial JVM products enhanced with alternate technical implementations such as a specialized garbage-collector   Both of their lines offer installers for macOS  I am currently use Zulu for Java 10 0 1 on macOS High Sierra with IntelliJ 2018 2 and Vaadin 8  I downloaded from this page  By the way  I do not find any Java-related items installed on the Apple System Preferences app  Adoptium Adoptium  formerly known as AdoptOpenJDK  is a community-led effort to build binaries of the OpenJDK source  Many of the other vendors of Java implementations support this work at Adoptium   Your choice of either HotSpot or OpenJ9 engine  Builds available for macOS  Linux  and Windows  and other platforms   OpenJ9 by Eclipse The OpenJ9 project is an another implementation of the JVM engine  an alternative to HotSpot  Now sponsored at the Eclipse Foundation  with technology and backing donated by IBM in 2017  For prebuilt binaries  they refer you to the AdoptOpenJDK project mentioned above    How to install The installers provided by Oracle or by Azul are both utterly simple to operate  Just run the installer app on your Mac  A window appears to indicate the progress of the installation  When completed  verify your JVM installation by   Visiting the  Library Java JavaVirtualMachines  folder to see an item for the new JVM  Running a console such as Terminal app and type java -version to see the brand and version number of your JVM   After verifying success  dismount the  dmg image in the Finder  Then trash the  dmg file you downloaded
