Java程序的简单介绍(中文4700字,英文2900字)
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。
Brief introduction of the Java program
Java was designed to solve the application development in the context of
distributedheterogeneous network problems in. In these complex problems, the first is security issuedapplication, minimal consumption of system resources, can run on any hardware and softwareplatforms and be dynamically extended.
Java was originally developed as a part of the research and development program, thisresearch program is to network devices and embedded system wide diverse development of high-level software. The goal is to develop a distributed operating system platform of small,high reliability, portability, and real-time. When the program began, C++ is the language of choice, but after a period of time, met with the C++ language difficulty is increased, the best way to solve these problems is to create a new language platform. The design and architecture decided to draw many languages, such as Eiffel, SmallTalk, Objective, C andCedar/Mesa. The results show that language is the ideal platform for application, end usernetwork based on the development of a high reliability, portability and distributed widely in various environments, from the embedded network device to search the web and desktop computer. |
