OpenJDK (Open Java Development Kit) is a free and open-source implementation of the Java Platform, Standard Edition (Java SE). It is the result of an effort Sun Microsystems began in 2006. OpenJDK is the official reference implementation of Java SE since version 7.

CPython is the reference implementation of the Python programming language. Written in C and Python, CPython is the default and most widely used implementation of the Python language. CPython can be defined as both an interpreter and a compiler as it compiles Python code into bytecode before interpreting it.

The Reference Implementation (RI) is a simulator that can be built with a ROM mask, much like a Java Card technology-based implementation for actual field use. The Java Card RI supports the following: Up to 20 logical channels per communication interface.

Reference software is software which emulates and expands upon print reference forms including the dictionary, translation dictionary, encyclopaedia, thesaurus, and atlas. Reference software may include multimedia content including animations, audio, and video, which further illustrate a concept.

In the software development process, a reference implementation (or, less frequently, sample implementation or model implementation) is a program that implements all requirements from a corresponding specification.

Java SE (Standard Edition) is for building desktop apps. Java ME (Micro Edition) is for old mobile devices. Java EE (Enterprise Edition) is for developing web based applications.

How to Cite Software in APA Style

1. Use an individual’s name in the reference if he or she has proprietary rights to the program.
2. After the title, in brackets, provide a descriptor for the item.
3. If the software is available online, provide the URL rather than the publisher name and location.

By using reference managers, it is no longer necessary to maintain a system of printing papers and putting them in binders. Managers also make it easy to share articles with collaborators, and to format in-text citations and bibliographic references while composing a manuscript.

PyPy (/ˈpaɪpaɪ/) is an alternative implementation of the Python programming language to CPython (which is the standard implementation). Since interpreters are usually easier to write than compilers, but run slower, this technique can make it easier to produce efficient implementations of programming languages.

There is no real technical difference between the two since the build process for the Oracle JDK is based on that of OpenJDK. When it comes to performance, Oracle’s is much better regarding responsiveness and JVM performance. It puts more focus on stability due to the importance it gives to its enterprise customers.

In the software development process, a reference implementation (or, less frequently, sample implementation or model implementation) is the standard from which all other implementations and corresponding customizations are derived.

The official Reference Implementation for Java SE 11 ( JSR 384) is based solely upon open-source code available from the JDK 11 Project in the OpenJDK Community . This Reference Implementation applies to both the Final Release of JSR 384 (Sep 2018) and Maintenance Release 1 (Mar 2019).

Reference Implementation for Maintenance Release 1 (Mar 2015) and Maintenance Release 2 (Mar 2019) contains RIs for these releases. Binaries are provided for both the Linux x64 and Windows i586 platforms and Compact Profiles for Linux i586. These binaries are for reference use only!
