Java is a type of software commonly used by major computer operating systems such as Windows, Linux, and Mac. It ensures that these applications are running on a safe working environment. It enables developers to create different types of software for specific platforms and provides copies that can be easily accessible to other platforms.
Java allows users to execute web applications, games, and other web services. Java Runtime Environment integrates a virtual machine which allows users to access a wide collection of core classes which are adjacent to platform libraries. It also deploys a plugin which smoothens the execution of the applets in the local browser.
Java Runtime Environment automatically works once it can sense applications that run on .jar. This platform also has a Control Panel feature that allows users to easily configure the current network and secure temporary internet files settings. Aside from these features, users can also access other JRE settings and other advanced features like Java Console, Default Java for Browsers, Java Plugin, JavaFX Runtime, and JRE Auto-Download.

Why Do I Need Java to Use Apache OpenOffice?
Java is required for complete OpenOffice functionality. Java is mainly required for the HSQLDBdatabase engine (used by our database product Base) and to make use of accessibility and assistive technologies.Furthermore some wizards rely on Java technology. See additional topics pertaining to the use of Java in OpenOfficeand Apache OpenOffice in theInstallation FAQ.
So what does this mean exactly? Base (the database component) relies completely on Java technologies to run, but otherprograms (like Writer, Calc and Impress) only need Java for special functionality. If you do not need to use Base and donot want to use any of the Wizards, then you do not need to have Java installed and configured for running ApacheOpenOffice (and older versions of OpenOffice.org). You can completely prevent OpenOffice from prompting you about the useof Java by telling OpenOffice not to use a Java runtime environment (JRE). From the OpenOffice main menu use:'Tools - Options... - Java', and uncheck 'Use a Java runtime environment'. However, we do recommendthat you have a JRE on your system to take full advantage of OpenOffice's features without any issues.
Legacy versions of OpenOffice.org 3.3.0 and older included a JRE packaged with the download. Apache OpenOffice3.4.0 and newer do not!
Which Java Version Do I Need to Use Apache OpenOffice?
You will need to have a JRE version (32-bit or 64-bit) that is compatible with the architecture of the ApacheOpenOffice version you downloaded. If you already have a JRE installed on your system that satisfies this requirement inone of the standard areas for Java installation, OpenOffice should detect this installation and let you choose it for usein OpenOffice via the 'Tools - Options... - Java'. If you have a JRE installed that is not detected,you should be able to add it through this same menu. And, you can install a JRE or configure OpenOffice to use Java at anytime to get missing functionality to work.
Important note for Windows users:
The Windows version of OpenOffice is 32-bit and therefore it requires a 32-bit JRE. Even when you have a Windows versionwith 64-bit installed.
Furthermore you have to install a 32-bit JRE - additionally or instead - when you already have a64-bit JRE installed.
