Java Software Platform

The Java software platform is used for developing and running both enterprise and consumer-level software programs written in the Java programming language. Java OpenJDK and Java Zulu are two Java development kits (JDKs) used for developing Java-based applications. OpenJDK (Open Java Development Kit) is a free and open-source implementation of the Java Platform, Standard Edition (Java SE). Zulu JDK is an open-source build of the Java Platform Standard Edition (Java SE) and is based on the OpenJDK project.

The Java software platform is optimised to support developing and running programs written in the Java programming language e.g. OpenJDK, Zulu JDK, Java enterprise systems, SpecJBB, etc.
