Java is a new object-oriented programming language that was developed by Sun Microsystems for programming the Internet and intelligent appliances. In a very short time it has become one of the most widely used programming languages for education as well as commercial applications.Design patterns, which have moved object-oriented programming to a new level, provide programmers with a language to communicate with others about their designs. As a result, programs become more readable, more reusable, and more easily extensible.In this book, Matthias Felleisen and Daniel Friedman use a small subset of Java to introduce pattern-directed program design. With their usual clarity and flair, they gently guide readers through the fundamentals of object-oriented programming and pattern-based design. Readers new to programming, as well as those with some background, will enjoy their learning experience as they work their way through Felleisen and Friedman's dialogue.

利用经验累积而得到的洞察力开发新的解决方案被称为预构。透过重构而获得的专业知识也属于这类经验，而预构的词源即重构。重构是修改程序或软件系统内部结构的实践，以此在保留其现有行为的基础上改良设计。重构的原因有多种：方便后期增加功能、提高可维护性、提升性能。 本书作者是经验老道的软件开发人员。书中，作者运用他个人和其他众多开发人员的丰富经验，展示由其推衍而得的各项实践方针。这些方针把优秀的开发人员在设计时隐而未显的考虑细节如实地呈现出来。许多方针都围绕着极致抽象化、极致隔离以及极致可读性这几个概念。在假想的软件项目和实际项目的介绍中，作者把实践方针呈现在读者面前。其中几条于稍后列出。 把作者的方针应用到你的软件项目，有助于写出可读性、可维护性更棒的程序。这些方针可以协助你前期决策，以减少后期重构的工作量。在这样的前提下，你可以预测未来，减少修改。简言之，就是程序预构会使你更有效率。

As a web developer, you’ll already know that JavaScript™ is a powerful language, allowing you to add an impressive array of dynamic functionality to otherwise static web sites. But there is more power waiting to be unlocked--JavaScript is capable of full object-oriented capabilities, and by applying OOP principles, best practices, and design patterns to your code, you can make it more powerful, more efficient, and easier to work with alone or as part of a team. With Pro JavaScript Design Patterns, you’ll start with the basics of object-oriented programming in JavaScript applicable to design patterns, including making JavaScript more expressive, inheritance, encapsulation, information hiding, and more. With that covered, you can kick-start your JavaScript development in the second part of the book, where you’ll find detail on how to implement and take advantage of several design patterns in JavaScript, including composites, decorators, façades, adapters, and many more. Each chapter is packed with real-world examples of how the design patterns are best used and expert advice on writing better code, as well as what to watch out for. Along the way you’ll discover how to create your own libraries and APIs for even more efficient coding. * Master the basics of object-oriented programming in JavaScript, as they apply to design patterns. * Apply design patterns to your kick-start your JavaScript development. * Work through several real-world examples.

你是否早已对市面上那些只有在成为专家以后，读起来才有感觉的 OOA&D 书籍感到厌倦？你可能早就听说过 OOA&D 书籍能帮助你写出伟大的软件 — 让老板高兴、客户满意的软件。. 但如何办到呢？ 《深入浅出面向对象分析和设计》将告诉你如何分析、设计以及撰写真正面向对象的软件：容易重利用、好维护、可扩展的软件；不再使你心碎的软件；让你增添新功能而不会破坏旧机制的软件。在本书中，你将学到： ·使用诸如封装（encapsulation）与委派（delegation）的 OO 原则建立灵活的应用程序。 ·使用开闭原则（Open-Closed Principle）与单一责任原则（Single-Responsibility Principle）提升程序的重利用性。 ·学习如何将 OO 原则、设计模式及各种开发方法，通通整合到 OOA&D 项目的生命周期里。 ·运用 UML、用例及用例图来确保所有利害关系人都能清楚地进行沟通，协助你交付正确的软件，达到每个人的要求。...

You're not alone. At any given moment, somewhere in the world someone struggles with the same software design problems you have. You know you don't want to reinvent the wheel (or worse, a flat tire), so you look to Design Patterns--the lessons learned by those who've faced the same problems. With Design Patterns, you get to take advantage of the best practices and experience of others, so that you can spend your time on... something else. Something more challenging. Something more complex. Something more fun. You want to learn about the patterns that matter--why to use them, when to use them, how to use them (and when NOT to use them). But you don't just want to see how patterns look in a book, you want to know how they look "in the wild". In their native environment. In other words, in real world applications. You also want to learn how patterns are used in the Java API, and how to exploit Java's built-in pattern support in your own code. You want to learn the real OO design principles and why everything your boss told you about inheritance might be wrong (and what to do instead). You want to learn how those principles will help the next time you're up a creek without a design paddle pattern. Most importantly, you want to learn the "secret language" of Design Patterns so that you can hold your own with your co-worker (and impress cocktail party guests) when he casually mentions his stunningly clever use of Command, Facade, Proxy, and Factory in between sips of a martini. You'll easily counter with your deep understanding of why Singleton isn't as simple as it sounds, how the Factory is so often misunderstood, or on the real relationship between Decorator, Facade and Adapter. With Head First Design Patterns, you'll avoid the embarrassment of thinking Decorator is something from the "Trading Spaces" show. Best of all, in a way that won't put you to sleep! We think your time is too important (and too short) to spend it struggling with academic texts. If you've read a Head First book, you know what to expect - a visually-rich format designed for the way your brain works. Using the latest research in neurobiology, cognitive science, and learning theory, Head First Design Patterns will load patterns into your brain in a way that sticks. In a way that lets you put them to work immediately. In a way that makes you better at solving software design problems, and better at speaking the language of patterns with others on your team.
