Java是一种程序设计平台
Java是一种优秀的程序设计语言。对于一个名副其实的程序设计人员来说,使用Java无疑是一个好的选择。有人认为:Java将有望成为一种最优秀的程序设计语言,但还需要一个相当长的发展时期。一旦一种语言应用于某个领域,与现存代码的相容性问题就摆在了人们的面前。”
Java并不只是一种语言。在此之前出现的那么多种语言也没有能够引起那么大的轰动。Java是一个完整的平台,有一个庞大的库,其中包含很多可重用的代码和一个提供诸如安全性、跨操作系统的可移植性以及自动垃圾回收等服务的执行环境。
作为一名程序设计人员,常常希望能够有一种语言,它具有令人赏心悦目的语法和易于理解的语义(C++不是这样的)。与许多其他的优秀语言一样,Java恰恰满足了这些要求。有些语言提供了可移植性、垃圾回收等等,但是,没有提供一个大型的库,如果想要有奇特的绘图功能、网络连接功能和数据库存取功能就必须自己动手编写代码。Java这种功能齐全的出色语言,具有高质量的执行环境以及庞大的库。正是因为它集多种优势于一身,所以对于广大的程序设计人员来说有着不可抗拒的吸引力。

Java Technical Description
Java as a Programming Platform
Java is certainly a good programming language. There is no doubt that it is one of the better languages available to serious programmers. We think it could potentially have a great programming language, but it is probably too late for that. Once a language is out in the field, the ugly reality of compatibility with existing code sets in."
Java was never just a language. There are lots of programming languages out there, and few of them make much of a splash. Java is a whole platform, with a huge library, containing lots of reusable code, and an execution environment that provides services such as security, portability across operating systems, and automatic garbage collection.
