简介
本书的最大特点之一是作者采用类比而不是编程实例的方式将概念解释得非常清楚。我正在做一套关于OOP和软件开发的音频产品,这种讲述概念的方式给予我很大的启发。
--Bruce Eckel.
希望那些仅基本了解面向对象编程和设计的读者,在完全接触设计模式之前,能够发现这本有用的书。本书是对现有的设计模式教材的补充,并可以在入门级教材 (如《UML Distilled》) 和更高级模式著作之间充当一个很好的衔接。
--James Noble..
本书是模式领域最简洁、最清晰、最实用的著作,阐述了模式如何使整个开发过程变得更加容易,解释了面向对象设计的关键原则,以及各种特定模式的概念和优势。通过采用许多最新的Java示例,本书精确地向程序员和架构师展示出如何使用模式来更有效地设计、开发和交付软件。通过分析Java示例,本书提示了为什么、为什么不以及如何应用模式,而且解释了模式的实现。
以畅销的第1版为基础,作者对本版进行了彻底更新,以反映新的软件设计趋势、模式和实现技术。根据广大读者的反馈,作者在第2版中加深了全书概念的阐述,并重新组织了全书内容,使其更易于理解。本书首先概述了模式的基础知识,以及面向对象分析和设计在当代软件开发中的重要性。随后,使用易懂的示例代码阐明了许多当今最有用的模式,包括它们的基础概念、优点、权衡取舍、实现技术以及需要避免的缺陷。另外,许多模式都附有UML图。
本书假定读者没有模式方面的经验,因此是学习模式的理想的第一本书,对于GoF的经典名著《设计模式》,本书也是一个很好的补充。本书适用于学习面向对象设计和设计模式的学生、程序员以及从事软件开发的人士。
