See 'OS X Platform Install FAQ' for general information about installing JRE 8 on OS X.
System Requirements
Observe these requirements:
Note that installing the JRE 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.
Only one JRE can be installed at a time. The system will not install a JRE that has a lower version than the current version. If you wish to install a lower version of the JRE, uninstall the current version as described in 'Uninstalling the JRE'.
Installing a JRE from Oracle will not update
java -version symlinks or add java to your path. To be able to do this, you need to install the JDK.
JRE Downloaded File
Depending on your processor, the downloaded file has one of the following names, where
version is the update number:
Installing JRE 8u40
If you are installing JRE 8u40, then follow these steps:

Only one JRE can be installed. Installing a JRE removes the previously installed JRE. The JRE version used by the system can be determined in one of two ways:
The system will not install a JRE that has a lower version than the current version. If you want to install a lower version, first uninstall the existing version.

To uninstall the JRE, you must have Administrator privileges and execute the remove commands either as root or by using the sudo(8) tool.
Remove one directory and one file (a symlink), as follows:
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.
