Java Runtime Environment for Mac 2018 full offline installer setup for Mac Java Runtime Environment for Mac (JRE for Mac) allows you to play online games, chat with people around the world, calculate your mortgage interest, and view images in 3D, just to name a few. Java content is common on the Internet. As of the release of Java 7 Update 6, you can download and install Java for Mac OS X directly from the Java.com web site. There is no longer a need to get Java updates from the App Store (or from Software Updates). To download and install Java for Mac OS X, just follow these steps.

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
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?

Don't rely on Oracle to install Java properly on your Mac.
Use Homebrew. this will install the latest jdk:
If you want to manage multiple versions of Java on your Mac, consider using jenv.
UPDATE: Now that Java 8 is no longer the most current version, if you want Java 8 install it this way:
To get a list of all older versions of java:
brew tap caskroom/versions and then use brew search java .
We use brew cask since we'd otherwise use the Oracle GUI installer that will likely not install Java properly on your Mac. (Use brew cask install APP to install GUI apps; use brew install APP.) Java is not a GUI app; It should not require 'cask' but at least Oracle is consistent.

Java8 is no longer available on homebrew,
brew install java8 will not work.
Instead, use:

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:
A very simple example:
Create a
Dockerfile :
Create a
docker-compose.yml file:
Now, assume we have this Java file:
HelloWorld.java
It is able to stream over networks and to transcode multimedia files and save them into various formats. VLC is a portable multimedia player, encoder, and streamer supporting many audio and video codecs and file formats as well as DVDs, VCDs, and various streaming protocols. Cnet escribe download for mac. VLC media player is a free and open source media player and multimedia framework written by the VideoLAN project.
So we have the following file structure:
You can do various Java things like:
compile:
run:
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

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).However, I tell you how I solve all problems on a Mac (Sierra).
First, you need brew with cask and jenv.
You could find other useful informations here on this Github Gist brew-java-and-jenv.md, on this blog Install multiple JDK on a Mac and on Jenv Website

Assumption: Mac machine and you already have installed homebrew.
Install cask:
To install latest java:
To install java 8:
If you want to install/manage multiple version then you can use 'jenv':
Install and configure jenv:
Add the installed java to jenv:

Above command will give the list of installed java:

If you have several Java versions on your machine and you want to choose it dynamically at runtime, i.e, in my case, I have two versions:
You can change them by modifying the
/etc/profile content. Just add (or modify) the following two lines at the end of the file:
In my case, it should be like the following if I want to use:
Java 7:
Java 8:
After saving the file, please run
source /etc/profile and it should work. Here are results when I use the first and second option accordingly:
Java 7:
Java 8:
The process is similar if your java folder is located in different locations.

You have multiple sources to obtain an easy-to-use installer app to put Java on your Mac. Other answers suggesting Brew or other approaches seem a bit extreme to me. Just download a Mac installer from a trusted source and run it.
Here is a flowchart diagram for finding a source of Java 11, some of which also offer Java 8.
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.
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
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 are three currently-active sources I know of.
Oracle JVM
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.
Zulu & Zing by Azul
Azul Systems provides a variety of JVM products.
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.
AdoptOpenJDK.net
AdoptOpenJDK is a community-led effort to build binaries of the OpenJDK source. They intend to offer updates over time, as donated by community members.
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.
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:
After verifying success, dismount the .dmg image in the Finder. Then trash the .dmg file you downloaded.

It seems that nobody has mentioned SDK man (https://sdkman.io/) yet.
SKD man allows installing multiple versions of Java on Mac and easy switching between these versions. More information is available at https://sdkman.io/usage.

Best way is to use Brew package manager but the command
fails with error:
So use
How did I find 'caskroom/versions/java8': using brew search command:

If you are using it NOT for personal use, you might want to use OpenJDK instead to avoid any potential lawsuit from Oracle.

Easiest way -
P.S - What is brew-cask ? Homebrew-Cask extends Homebrew , and solves the hassle of executing an extra command - “To install, drag this icon…” after installing a Application using Homebrew.

Simplest is to download the dmg file from following site and install by double click
Safari 5.1.1 download for mac. look for available JVMs from home directory
and update the .bash_profile with relevent version
and finally

I would suggest using the SDK man that is quite easy to change the Version ( temporarily and permanent ) and it provides other SDKs as well. I have been using the SDK man for more than a year now.

Below steps worked for me.
1) Uninstall all jdks
In the Terminal window Copy and Paste the command below:
2) Install APPLE jdk.
3) Download latest JDK from Oracle and install it , for me it was JDK 1.82
Thats all it will work like a charm.

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.
Java Download For Mac Yosemite
Run following command after installation. It gives path for jdk 8./usr/libexec/java_home -v 1.8
Also you can run and see jdk 8 folder. The files may be hidden.ls -al /Library/Java/JavaVirtualMachines/
