Note that installing the JDK on OS X is performed on a system wide basis, for all users, and administrator privileges are required. You cannot install Java for a single user.
Installing the JDK also installs the JRE. The one exception is that the system will not replace the current JRE with a lower version. To install a lower version of the JRE, first uninstall the current version as described in 'Uninstalling the JRE'.
JDK Installation Instructions
When you install the Java Development Kit (JDK), the associated Java Runtime Environment (JRE) is installed at the same time. The JavaFX SDK and Runtime are also installed and integrated into the standard JDK directory structure.

Determining the Default Version of the JDK
If you have not yet installed Apple's Java OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See 'Note for Users of OS X that Include Apple Java 6 Plug-in'.
There can be multiple JDKs installed on a system, as many as you wish.
When launching a Java application through the command line, the system uses the default JDK. It is possible for the version of the JRE to be different than the version of the JDK.
You can determine which version of the JDK is the default by typing
java -version
in a Terminal window. If the installed version is 8u6, you will see a string that includes the text 1.8.0_06. For example:To run a different version of Java, either specify the full path, or use the
java_home
tool:Download Java For Mac Os Sierra
For more information, see the java_home(1) man page.
Uninstalling the JDK
Mac Install Oracle Jdk

For example, to uninstall 8u6:
Download Java 8 For Mac Os Sierra
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.
