The Java Runtime Environment (JRE) is what you get when you download Java software. The JRE consists of the Java Virtual Machine (JVM), Java platform core classes, and supporting Java platform libraries. The JRE is the runtime portion of Java software, which is all you need to run it in your Web browser.
Java technology allows you to work and play in a secure computing environment. Upgrading to the latest Java version improves the security of your system, as older versions do not include the latest security updates. Java allows you to play online games, chat with people around the world, calculate your mortgage interest, and view images in 3D, just to name a few.
Java 8 is the latest release for Java that contains new features, enhancements and bug fixes to improve efficiency to develop and run Java programs. The new release of Java is first made available to developers to ensure no major problems are found before we make it available on the java.com website for end users to download.
Some application providers might require that you use a particular Java release and have not certified their applications with Java 8. If you experience problems running an application with Java 8, check with your application provider and confirm that it is certified with this version.
