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.

Determining the Default Version of the JDK
A: If you have not yet installed Apple's Java Mac 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 Macs 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 7u6, you will see a string that includes the text 1.7.0_06. For example:
To run a different version of Java, either specify the full path, or use the java_home tool:
For more information, see the java_home(1) man page.
Uninstalling the JDK
To uninstall the JDK, you must have Administrator privileges and execute the remove command either as root or by using the sudo(8) tool.
Navigate to /Library/Java/JavaVirtualMachines and remove the directory whose name matches the following format:*
For example, to uninstall 7u6:
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.
*The 7u4 and 7u5 releases were installed into a directory that does not follow this format. To uninstall 7u4 or 7u5, remove the 1.7.0.jdk directory from the same location.

This quick guide explains how you can fix the LibreOffice requires a Java runtime environment (JRE) error.
LibreOffice – the free office suite requires Java runtime environment for some of its own functionalities. For example, some of the plugins, extensions, Python macros require Java Runtime Environment (JRE) to work.
Lack of JRE, would cause the below error in LibreOffice:
