通用，高级Java编程语言是一个强大的软件平台。Java平台的每个完整实现给你提供以下功能：

  • Development Tools：开发工具提供所有compiling（编译），running（运行），monitoring（监控），debugging（调试），documenting（编写文档）时需要用的东西。作为一个新手你使用的主要工具是javac(编译器)，java（启动器）和javadoc（文档工具）。

  • Application Programming Interface (API)：API提供Java编程语言的核心功能。它提供了大量有用的类，你可以在自己的程序用使用到。它涵盖了从基本对象到网络和安全、以及XML生成和数据库访问等所有方面。核心API是非常庞大的，如果想了解它包含的内容，请参考。

  • Deployment Technologies：JDK提供了标准的机制，比如Java Web启动软件和Java插件软件，用于将应用程序部署并为终端用户提供服务。

  • User Interface Toolkits：JavaFX，Swing，以及Java 2D工具包使得创建复杂的图形用户界面（GUI）成为可能。

  • Integration Libraries：集成库，比如Java IDL API、JDBC API、JDBC API, Java Naming and Directory Interface (JNDI) API、Java RMI和基于Internet Inter-ORB Protocol的Java Remote Method Invocation(Java RMI-IIOP)，实现了对数据库的方位和远程对象的操作。
