J2EE Basics: Modules in Java Programming 📘

JSE – Java Standard Edition:
Java Platform, Standard Edition or Java SE is a widely used platform for programming in the Java language. It is the Java Platform used to deploy portable applications for general use. In practical terms, Java SE consists of a virtual machine, which must be used to run Java programs, together with a set of libraries (or "packages") needed to allow the use of file systems, networks, graphical interfaces, and so on, from within those programs.
The other two environments (JME and JEE) are based on JSE.

JME – Java Micro Edition:
Java Platform, Micro Edition, or Java ME, is a Java platform designed for embedded systems (mobile devices are one kind of such systems) . Target devices range from industrial controls to mobile phones (especially feature phones) and set-top boxes.

JEE – Java Enterprise Edition :
The Java platform Enterprise Edition differs from the Java Standard Edition Platform (JSE) in that it adds libraries which provide functionality to deploy fault-tolerant, distributed, multi-tier Java software, based largely on modular components running on an application server.
