JRE is an implementation of the Java Virtual Machine (JVM), which allows you to run compiled Java applications and applets. There are threee variation of Java, the Standard Edition (SE), the Enterprise Edition (EE) and the Micro Edition (ME) while there are two more versions of SE that we can install, those are the Java Runtime Environment (JRE) and the Java Development Kit (JDK).

From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!īefore installing Java you should have a root or a non-root account with sudo enabled on your distribution. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is a programming language and computing platform first released by Sun Microsystems in 1995.
