Java is divided into three systems JavaSE (Java2 Platform Standard Edition, java platform standard edition), JavaEE (Java 2 Platform, Enterprise Edition, java platform enterprise edition), JavaME (Java 2 Platform Micro Edition, java platform, Micro Edition). Java SE JAVA

* Java SE (Java Platform, Standard Edition). Java SE formerly known as J2SE. It allows development and deployment on the desktop, server, embedded and real-time environment using the Java environment applications. Java SE includes support for Java Web services development classes, and for the Java Platform, Enterprise Edition (Java EE) to provide a basis. Java EE

* Java EE (Java Platform, Enterprise Edition). This version formerly known as J2EE. Enterprise Edition to help develop and deploy portable, robust, scalable and secure server-side Java applications. Java SE Java EE is built on the foundation, which provides Web services, component model, management and communication API, can be used to achieve enterprise class service-oriented architecture (service-oriented architecture, SOA) and Web 2.0 applications program. Java ME

* Java ME (Java Platform, Micro Edition). This version formerly known as J2ME. Java ME devices in mobile and embedded devices (such as mobile phones, PDA, TV set-top boxes and printers) applications running on a robust and flexible environment. Java ME includes flexible user interfaces, robust security model, and many built-in network protocols and networking that can be dynamically downloaded the rich and offline application support. Specification based on Java ME applications are written once, can be used in many devices, and can use each device's native capabilities. Origin of name

The birth of Java since 1995, it has been 16 years. The name of the source Java: Java is the English name of the Indonesian island of Java, known for rich coffee. Many libraries in

the Java language class name, more and more coffee, such as JavaBeans (coffee beans), NetBeans (Web Beans) and ObjectBeans (Object bean) and so on. SUN and JAVA identity is what is steaming cup of coffee.

According to James Gosling memories, TV set-top box was originally designed this as the language has been called the Green in Sun internal project. Our new language needs a name. Gosling noted that his thick oak tree outside the office of Oak, which is a very common tree in the Silicon Valley. So he named this new language Oak. But the Oak is another registered company name. The name can not be used again.

Call the meeting in the name, we made a lot of names. Final selection by our order of a dozen names will be arranged in the table, reported to the Attorney. Ranked first in the Silk (silk). Although we like the name, but was firmly opposed to James Gosling. Came in second and third did not pass the hurdle of lawyers. Only the name in fourth place, got all the recognition and adoption lawyers, the name is Java.

10 years, Java as Java, as world famous coffee, as deserved the dominant platform for enterprise applications. The Java language is like a coffee generally mellow and moving. Early Java

Java platform and language is just the beginning of 12 in 1990, Sun Microsystems began to study an internal project. Sun Microsystems, a named Patrick Norton ? Sun engineers are developing their own C and C compiler whipped, because the API is extremely difficult to use. Patrick decided to switch to NeXT, he also received a company called \

\n Patrick has also joined the working group. They and several other engineers in California, Sand Hill Road Menlo Park City studio inside a small research and development of new technologies, aimed at the next generation of intelligent home appliances (eg microwave ovens) programming, Sun Microsystems is expected that future technology will be appliances areas of their talents. Team initially considered using the C language, but many members include Sun Microsystems chief scientist Bill Joy ? and found that C and the available API in some respects there is a big problem.

Working groups are embedded type of platform, can be extremely limited resources. Many members find that C is too complex as well as many developers often used incorrectly. They found that the lack of garbage collection system C, as well as the safety of portable, distributed programming, and multi-threading capabilities. Finally, they want an easy migration to a variety of device platforms.

According to available funds, Bill Joy decided to develop a set of ? C language Great language and new language Mesa, in a report, Joey called it \Sun's engineers should be C, Based on the development of an object-oriented environment. Initially, Gosling attempt to modify and extend the function of C, he said the new language is C -, but later he gave up. He will have to create a new language, which he named \

Like many of the secret development of new technology projects, the Working Group to work day and night to the summer of 1992, they are able to demonstrate a part of the new platform, including the Green Operating System, Oak programming language, libraries, and its hardware. First attempt is a class for PDA devices, named Star7, this device has

bright graphical interface and is known as \intelligent agents to help users. December 3, 1992, this equipment was displayed.

In the same year in November, Green plans to be transformed into \Limited\Palo Alto. FirstPerson team building interest in a highly interactive devices, when Time Warner issued a request for proposals on the TV set-top box book (Request for proposal), FirstPerson changed their goal to seek submissions as a response to proposed proposed a set-top box platform. But the cable industry that FirstPerson platform to give users too much control, so lost to the FirstPerson tender SGI. 3DO Company and the other a transaction on the set-top bo …… 此处隐藏：8145字，全部文档内容请下载后查看。喜欢就下载吧 ……
