Java Runtime Environment 8 Update 20 / 9 Build 31 Early Access
Platform portability is one of its major advantages and thanks to this, almost every piece of electronic equipment in the world uses Java technologies. Billions of PCs, mobile phones, Blu-ray players, printers, medical devices, car navigation systems or webcams make us of it.
Java enables developers to create software on one platform and provide it to users running other platforms. Thus, an application developed on Windows can successfully run on Mac or Linux and vice versa. Java Runtime Environment allows the execution of almost any software, from games to web applications and services.
Running JAR applications
Java Runtime Environment (JRE) incorporates a virtual machine (also known as the Java Virtual Machine), a collection of core classes and adjacent platform libraries. Actually, JRE represents a runtime environment for the virtual machine and is the part that allows users to run .jar applications (Java archive, proprietary Java format). During installation, Java Runtime Environment also deploys a plugin that facilitates the execution of applets within local browsers.
How it works
While Java sits patiently on the computer, it instantly acts when called upon. And that happens more often than you may think of. Whether you play online games or chat with your friends, Java is running in the background making sure you have an enjoyable experience.
Oracle's platform also features a Control Panel that allows the configuration of network and temporary Internet file settings or security certificates. You can also manage the settings of the JRE and access more advanced functions such as Debugging, Java console, Default Java for Browsers, Java Plug-in, JavaFX runtime, JRE Auto-Download or Security.
An essential tool for developing software and deploying it in a cross-platform environment
The Java Runtime Environment is also meant to be distributed by developers alongside their main Java application. This way, they make sure that you will be able to run their Java-written programs. It is used at large scale on various devices and has reached a usability level to the point where having it is not optional anymore.

- NEW FEATURES AND CHANGES:
- New flags added to Java Management API:
- The flags MinHeapFreeRatio and MaxHeapFreeRatio have been made manageable. This means they can be changed at runtime using the management API in Java. Support for these flags have also been added to the ParallelGC as part of the adaptive size policy.
