This is the reference implementation of the programming language Java. It is an interpreter, written in Unknown language. It has unknown licensing terms. Dependencies To run this implementation, you need only download and install the appropriate version for your computer and operating system. Links http://www.oracle.com/technetwork/java/javase/downloads/jdk7u7-downloads-1836413.html Commentary Because most of our distributions which include a Java implementation also include prebuilt .class files, all you really need to run them is the Java SE 6 JRE 1.6.0 from Oracle. But we suggest installing the JDK, in case you want to rebuild the .class files.
