What are the three major systems of java

The three major systems of java are JavaEE, JavaSE, and JavaME. This allows software developers, service providers and device manufacturers to target specific markets.

Java SE (Java Platform, Standard Edition)

Standard Edition, formerly known as J2SE. It allows the development and deployment of Java applications for use in desktop, server, embedded and real-time environments. Java SE contains classes that support Java Web services development and provides the foundation for Java Platform, Enterprise Edition (Java EE).

Java EE (Java Platform, Enterprise Edition)

Enterprise Edition, formerly known as J2EE. It helps develop and deploy server-side Java applications that are portable, robust, scalable, and secure. Java EE is built on Java SE and provides Web services, component models, management and communication APIs that can be used to implement enterprise-class service-oriented architecture (SOA) and Web 2.0 applications.

Java ME (Java Platform, Micro Edition)

Micro Edition, formerly known as J2ME. It provides a robust and flexible environment for applications running on mobile and embedded devices such as cell phones, PDAs, television set-top boxes, and printers. Java ME includes a flexible user interface, a robust security model, many built-in network protocols, and rich support for networked and offline applications that can be downloaded dynamically. Applications based on the Java ME specification can be written once for many devices and take advantage of each device's native capabilities.
