序言

1995年底，Java语言在Intemet舞台上一亮相便名声大噪。其原因在于它将有望成为通过信息将用户联系起来的“万能胶”，而不论这些信息来自于Web服务器、数据库、信息提供商，还是任何其他渠道。事实上，就发展前景而言，Java的地位是独一无二的。它是一种完全可以信赖的程序设计语言，得到了除微软之外所有厂家的认可。其固有的可靠性与安全性不仅令Java程序员放心，也令使用Java程序的用户放心。Java内建了对网络编程、数据库连接、多线程等高级程序设计任务的支持。 1995年以来，SUN MicroSystems公司已经发布了Java开发工具箱（Java Development Kit）的7个主要版本。在过去的11年中，应用程序接口（API）已经从200个类扩展到3000个类，并覆盖了用户界面构建、数据库管理、国际化、安全性以及XML处理等各个不同的领域。 本书是《Java核心技术》第8版的卷I。自《Java核心技术》出版以来，每个新版本都尽可能快地跟上Java开发工具箱发展的步伐，并重新改写部分内容，以适应Java的最新特性。在这一版中，已经反映了Java标准版（Java SE 6）的特性。 与前几版一样，本版仍然将读者群定位在那些打算将Java应用到实际工程项目中的程序设计人员。本书假设读者是一名具有程序设计语言（除Java之外）坚实背景知识的程序设计人员，并且不希望书中充斥着玩具式的示例（诸如烤面包机、动物园的动物或神经质的跳动文本）。这些内容绝对不会在本书中出现。本书的目标是让读者充分地理解书中介绍的Java语言及Java类库的相关特性，而不会产生任何误解。 在本书中，我们选用大量的示例代码演示所讨论的每一个语言特性和类库特性。我们有意使用简单的示例程序以突出重点，然而，其中的大部分既不是赝品也没有偷工减料。它们将成为读者自己编写代码的良好开端。
