The direct differences and linkages between Java SE, Java EE, Javame, Javaweb

This is in other people's blog copy, not I write

2. Java is a programming language. Java is divided into three major editions, SE is the Standard Edition, contains the Java Core Class library, mainly used for the development of desktop applications, EE is the Enterprise Edition, including SE, and extended parts (SERVLET,JDBC, etc.), mainly for the development of distributed network programs, ME is a miniature version, contains the SE Central classification Library, also has its own expansion part, mainly used to do mobile class, embedded development.

4. Java SE (Java platform,standard Edition). Java SE was formerly known as J2SE. It allows you to develop and deploy Java applications that are used in desktops, servers, embedded environments, and live environments. Java SE contains classes that support Java WEB Service development and provides the foundation for Java platform,enterprise Edition (Java EE).

6. Java EE (Java platform,enterprise Edition). This version was formerly known as the Java EE. The Enterprise Edition helps develop and deploy portable, robust, scalable, and secure server-side Java applications. Built on the Java SE, Java EE provides Web services, component models, management, and communication APIs that can be used to implement enterprise-class service-oriented architecture (service-oriented Architecture,soa) and Web 2.0 applications.

8. Java ME (Java platform,micro Edition). This version was formerly known as J2ME. Java ME provides a robust and flexible environment for applications running on mobile devices and embedded devices such as mobile phones, PDAs, TV set-top boxes, and printers. Java ME includes a flexible user interface, robust security model, many built-in network protocols, and rich support for Web and offline applications that can be dynamically downloaded. Applications based on the Java ME specification need to be written once, can be used for many devices, and can take advantage of the native capabilities of each device.

10. Java Web refers to the use of Java System development site class applications, JSP belongs to the Java Web category, JSP can be simply as a front-end page embedded Java code, will be compiled into a servlet container, and then the servlet will output HTML code, and eventually become the page we see
