'Java for OS X 2015-001 installs the legacy Java 6 runtime for OS X 10.11 El Capitan, OS X 10.10 Yosemite, OS X 10.9 Mavericks, OS X 10.8 Mountain Lion, and OS X 10.7 Lion. This package is exclusively intended for support of legacy software and installs the same deprecated version of Java 6 included in the 2014-001 and 2013-005 releases.
Step by step tutorial how to install Java JDK 8 in Windows 10, Mac OS X El-Capitan and Ubuntu 16. There's a ton of tutorial on how to install JDK on windows, mac os x and ubuntu. Here I wanna show you how to install JDK version 8 on specific Microsoft Windows 10, Mac OS X El-Capitan and Ubuntu Server 16.04.

My previous post about installing Java on OS X received quite a bit of traffic, and I felt that some of the information was outdated, and it became a little unclear after all the edits, so I’ve endeavoured to create a much easier to understand set of instructions.

Learn how to re-enable the Apple-provided Java SE 6 Java SE 6 web plug-in and Web Start features in OS X Lion and later. If, after installing Java for OS X 2014-001 and the latest version of Java 7 from Oracle, you want to disable Java 7 and re-enable the Apple-provided Java SE 6 web plug-in and Web Start functionality, follow these steps.

The instructions for installing the JDK (Java Development Kit) are a subset of the instructions for installing just the JRE, because Oracle provides an installer for the JDK.

Go to the Oracle Java downloads page and download the JDK installer. You should end up with a file named something similar to jdk-8u60-macosx-x64.dmg, but perhaps a newer version.
Open the .dmg Disk Image and run the installer.
Open Terminal
Edit the JDK’s newly installed Info.plist file to enable the included JRE to be used from the the command line, and from bundled applications:
The third line fixes a permissions issue create by using defaults write. The fourth line is not required, but makes the file more user-friendly if you open it again in a text editor.
Create a link to add backwards compatibility for some applications made for older Java versions:
Optional: If you’re actually using the JDK for software development, you may want to set the JAVA_HOME environment variable. The recommended way is to use /usr/libexec/java_home program, so I recommend setting JAVA_HOME in your .bash_profile like Jared suggests:
This will get the latest installed Java’s home directory by default, but check out man java_home for ways to easily get other Java home directories.

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.

If you’re running El Capitan, this is actually a little difficult now, because Apple added SIP (System Integrity Protection) to OS X. I have written a post explaining how to disable and enable SIP.

If you’ve disabled SIP, or are not running El Capitan yet, you can trick some applications into thinking legacy Java 6 is installed by creating two folders with the following commands in Terminal:

Java El Capitan Free

Java El Capitan Update

Don’t forget to enable SIP again after creating these directories.
