JAVA介绍(含外文出处)(中文4800字,英文3200字)
摘要：本文主要介绍Java语言是一个支持网络计算的面向对象程序设计语言。Java语言吸收了Smalltalk语言和C++语言的优点，并增加了其它特性，如支持并发程序设计、网络通信、和多媒体数据控制等。Java语言有下面一些特点:简单、面向对象、分布式、鲁棒、安全、可移植 、 高性能、多线程以及动态性。
关键字：面向对象  并发  可移植  多线程

JAVA介绍
Java是被设计用来解决在上下文分布式的异构网络中应用程序开发的问题。在这些复杂问题中，首要的是安全发布应用程序、消耗最小的系统资源、可以在任何硬件和软件平台上运行以及被动态地扩展。
Java最初是作为研发方案的一部分而开发的，这个研究方案是为了给广阔多样的网络设备和嵌入式系统开发高级的软件。目标是开发一个小巧的、可靠性高的、可移植的、分布式的、实时的操作系统平台。当这个方案开始的时候，C++是精选的语言，但是过了一段时间，用C++语言遇到的困难也随之增长，解决这些问题最好的办法是创造一个全新的语言平台。设计和体系结构的决定汲取了多种语言，例如Eiffel、 SmallTalk,、Objective C以及 Cedar/Mesa。结果证明这个语言平台是理想的，对于开发一个可靠性高的、可移植的、分布式的、基于终端用户网络的应用程序在多种环境中广泛搜索从嵌入网络的设备到万维网和桌上型电脑。

Introduction to Java

Java is designed to meet the challenges of application development in the context of heterogeneous, network-wide distributed environments. Paramount among these challenges is secure delivery of applications that consume the minimum of system resources, can run on any hardware and software platform, and can be extended dynamically.
Java originated as part of a research project to develop advanced software for a wide variety of network devices and embedded systems. The goal was to develop a small, reliable, portable, distributed, real-time operating platform. When the project started, C++ was the language of choice. But over time the difficulties encountered with C++ grew to the point where the problems could best be addressed by creating an entirely new language platform. Design and architecture decisions drew from a variety of languages such as Eiffel, SmallTalk, Objective C, and Cedar/Mesa. The result is a language platform that has proven ideal for developing secure, distributed, network based end-user applications in environments ranging from network-embedded devices to the World-Wide Web and the desktop.
