Java技术及SSH框架和Jsp技术的介绍(中文9600字,英文8200字)
Java,是一种可以撰写跨平台应用软件的面向对象的程序设计语言，由当时任职太阳微系统的詹姆斯•高斯林(James Gosling)等人于1990年代初开发。它最初被命名为Oak，目标设置在家用电器等小型系统的编程语言，来解决诸如电视机、电话、闹钟、烤而包机等家用电器的控制和通讯问题。由于这些智能化家电的市需求没有预期的高，Sun放弃了该项计划。就在Oak 几近失败之时，随着互联网的发展，Sun看到了 Oak在计算机网络上的广阔应 用前景，于是改造了 Oak,在1995年5月以“Java”的名称正式发布了。Java 伴随着互联网的迅猛发展而发展，逐渐成为重要的网络编程语言。Java编程 语言的风格十分接近C++语言。继承了 C++语言面向对象技术的核心，Java舍弃了C++语言中容易引起错误的指针（以引用取代）、运算符重载(operator overloading),多重继承（以接口取代）等特性，增加了垃圾回收器功能用于回收不被引用的对象所占据的内存空间。在JavaSE 1.5版本中Java 又引入 了泛型编程 (Generic Programming)、类型安全的枚举、不定长参数和自动装/ 拆箱等语言特性。

History
Duke, the Java mascotJames Gosling, Mike Sheridan, and Patrick Naughton initiated the Java language project in June 1991. Java was originally designed for interactive television, but it was too advanced for the digital cable television industry at the time. The language was initially called Oak after an oak tree that stood outside Gosling's office; it went by the name Green later, and was later renamed Java, from a list of random words .Gosling aimed to implement a virtual machine and a language that had a familiar C/C++ style of notation.
Sun Microsystems released the first public implementation as Java 1.0 in 1995. It promised “Write Once，Run Anywhere” (WORA), providing no-cost run-times on popular platforms. Fairly secure and featuring configurable* security, it allowed network- and file-access restrictions. Major web browsers soon incorporated the ability to run Java applets within web pages, and Java quickly became popular. With the advent of Java 2 (released initially as J2SE 1.2 in December 1998-1999), new versions had multiple configurations built for different types of platforms. For example, J2EE targeted enterprise applications and the greatly stripped-down version J2ME for mobile applications (Mobile Java). J2SE designated the Standard Edition. In 2006, for marketing purposes, Sun renamed new J2 versions as Java EE, Java ME, and Java SE, respectively. [资料来源：http://doc163.com]
