The Java Runtime Environment, or JRE, or J2RE is a software bundle from Sun Microsystems that allows a computer system to run a Java application. Java applications are in widespread use and necessary to view many Internet pages. As of 2007 normal computer users can download the current JRE version (Sun lists JRE 6.0, JRE 1.5 and JRE 1.4) by testing their Java Virtual Machine (JVM) at the Java.com test page.

The software bundle consists of the JVM and programming interface (API). The API provides a set of standard class libraries. The virtual machine and API have to be consistent with each other and are therefore bundled together as the JRE. This can be considered a virtual computer in which the virtual machine is the processor and the API is the user interface. A Java Virtual Machine (JVM) is a set of computer software programs and data structures which implements a specific virtual machine model. ... The software that provides the functionality described by an API is said to be an implementation of the API. The API itself is abstract, in that it specifies an interface and does not get involved with implementation details. ...
