由于这些智能化家电的市场需求没有预期的高，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， 是一种使用者不需花费很多时间学习的语言 科学超级计算机、移动电话和互联网，同时拥有全球最大的开发者专业社群。 另外编写和运行Java程序需要JDK(包括JRE)，在sun的官方网站上有下载，thinking in java第三版用的JDK版本是1.4,现在流行的版本1.5（sun称作J2SE 5.0，汗），不过听说Bruce的TIJ第四版国外已经出来了，是专门为J2SE 5.0而写的。 Java 编程语言的风格十分接近C、C++语言。 象、泛型编程的特性，广泛应用于企业级Web应用开发和移动应用开发。 是一种语言，用以产生「小应用程序(Applet(s)) 接着就是EJB了，EJB就是Enterprise JavaBean, 看名字好象它是Javabean，可是它和Javabean还是有区别的。它是一个体系结构，你可以搭建更安全、更稳定的企业应用。它的大量代码已由中间件（也就是我们常听到的 Weblogic,Websphere这些J2EE服务器）完成了，所以我们要做的程序代码量很少，大部分工作都在设计和配置中间件上。 Sun公司看见Oak在互联网上应用的前景，于是改造了Oak，于1995年5月以Java的名称正式发布。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、C++语言。 是一种突破用户端机器环境和CPU
