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

- Note: Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS. Install the older release of Java (Java 8 Update 161) 7. Next, visit the Oracle Java archive.
- The Java Development Kit (JDK), officially named 'Java Platform Standard Edition' or 'Java SE', is needed for writing Java programs.The JDK is freely available from Sun Microsystems (now part of Oracle).
- If your Mac running OS X Yosemite needs Java for application compatibility, online banking, or any of the myriad of other reasons, you can manually install one of two versions of Java that are compatible with OS X 10.10, either the latest version of JRE 8, or an older version from Apple which remains compatible with the newest version of OS X.
How to Install NetBeans on MacOS? NetBeans is a software development platform written in Java. It is an official IDE for Java 8 development. It was developed and released by Sun Microsystems which was later acquired by Oracle. NetBeans 8.2 was released on October 3, 2016.
but previous versions are at
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?
Answers:
Don’t rely on Oracle to install Java properly on your Mac.
Use Homebrew:
If you want to manage multiple versions of Java on your Mac, consider using jenv.

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
:- 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:Now, assume we have this Java file:
HelloWorld.java
So we have the following file structure:
You can do various Java things like:
![Install java on mac os Install java on mac os](https://neurogadget.net/wp-content/uploads/2016/06/whatsapp-8.jpg)
Download And Install Java 8 On Mac Os
compile:
- 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:
- 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 runningjava
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

I’m having the same problem to solve, because I need to install JDK8 to run Android SDK Manager (because it seems that don’t work well with JDK9).

First, you need brew with cask and jenv.

- You can find an useful guide here,Homebrew Cask Installation Guide.
Remember to tap ‘caskroom/versions’ running in the terminal:brew tap caskroom/versions
- After that, install jenv with:
brew install jenv
- Install whatever version you want with cask
brew cask install java8
(orjava7
orjava
if you want to install the latest version, jdk9) - The last step is to configure which version to run (and let jenv to manage your JAVA_HOME)
jenv versions
to list all versions installed on your machine and then activate the one you want withjenv global [JDK_NAME_OF_LIST]

I also had the same problem. But after little hit and trial, I was able to resolve the issue.
Try removing 1.6 sdk by sudo rm and restart your mac.
Download again the .dmg file. Chances are that the .dmg installer you downloaded, might be corrupt. Install again.
Run following command after installation. It gives path for jdk 8.
/usr/libexec/java_home -v 1.8
/usr/libexec/java_home -v 1.8

Also you can run and see jdk 8 folder. The files may be hidden.
