Java is no longer installed with a OS X 10.11 El Capitan clean install, and you’ll find that after updating a Mac a prior version of JRE may no longer function.
1) brew cask install java 2) java -version java version '1.8.0131' Java(TM) SE Runtime Environment (build 1.8.0131-b11) P.S - Cask is an extension to Homebrew that is intended to manage large Mac binaries and graphical applications, but using the Homebrew interface. What's new in Java for Mac OS X 2017-001: This package is exclusively intended for support of legacy software and installs the same deprecated version of Java 6 included in the 2015-001, 2014-001, and 2013-005 releases. With Mac OS 10.7 (Lion) and later, the Java runtime is no longer installed automatically as part of the OS installation. Follow any of the methods below to install Java runtime. Already own Minecraft? Download it again for Windows, Mac and Linux. Download server software for Java and Bedrock and play with your friends.
You may come across when trying to use some particular applications or web content, “This application requires the legacy Java SE 6 runtime which is unavailable for this version of OS X.” error message, which means if you want to run that app you’re going to need to use an older version of Java.
If you do not need Java, you should not install Java. Java is, and always has been, the source of many security holes.
Here’s how you can install JRE (Java Runtime Environment).
Step 1. Open Safari and go to the Oracle Java downloads page and download the JRE .tar.gz version. You should end up with a file named something similar to jre-8u65-macosx-x64.tar.gz.
Step 2. Go to your Downloads folder and extract the JRE download or use Terminal to extract files:
Step 3. Open Terminal
Step 4. Edit the Info.plist file within to enable the JRE to be used from the the command line, and from bundled applications:
Step 5. Move the JRE folder to the correct location:
Type password on prompt.
Be sure you are in the correct directory (the JRE folder) when you issue this command, because it will move your current directory to /Library/Java/JavaVirtualMachines/!
Step 6. Create a link to add backwards compatibility for some applications made for older Java versions:
You should be done now, so try and open the application. If it does not work, some applications require legacy Java 6 to be installed.
You can have it installed without actually using it, however, it’s possible to trick the applications into thinking legacy Java 6 is installed, without actually doing so.
Step 1.Disable SIP (System Integrity Protection) in OS X El Capitan. Here is tutorial to disable and enable SIP.
Step 2. Trick some applications into thinking that legacy Java 6 is installed by creating two folders with the following commands in Terminal:
Step 3. Don’t forget to enable SIP again after creating these directories.
If you would like to learn Java programming, the best way is by writing Java codes by yourself. To compile the Java codes then you need Java Development Kit (JDK). It can be Oracle JDK or OpenJDK. This post guides you how to install Oracle JDK 8 on Mac OS X 10.10 Yosemite. It should be also applicable for previous version of OS X such as OS X Maverick, Mountain Lion, and OS X Lion. At the time of this post written, the latest version of JDK is JDK 8 Update 25.
Basically I previously had written an article how to install Java SE 7 / JDK 7 on Mac OS X Lion. I just would like to rewrite on the newest version.
1. Download Oracle JDK 8 from Oracle website. You need to accept license agreement to be able to download the file. Make sure you select the Mac OS X x64 platform (jdk-8u25-macosx-x64.dmg).
2. Double-click the downloaded file ‘jdk-8u25-macosx-x64.dmg’ and follow the on-screen installation.
3. Once it is successfully installed, it is installed inside /Library/Java/JavaVirtualMachines folder.
4. Verify that the system is now using JDK 8.
5. If you would like to uninstall JDK 8, simply remove the jdk1.8.0_25.jdk

Hopefully this tutorial helps you on installing JDK 8 / Java SE 8 on Mac OS X 10.10 Yosemite.
