Written for the working Java developer, Joshua Bloch's Effective Java Programming Language Guide provides a truly useful set of over 50 best practices and tips for writing better Java code. With plenty of advice from an indisputable expert in the field, this title is sure to be an indispensable resource for anyone who wants to get more out of their code.
As a veteran developer at Sun, the author shares his considerable insight into the design choices made over the years in Sun's own Java libraries (which the author acknowledges haven't always been perfect). Based on his experience working with Sun's best minds, the author provides a compilation of 57 tips for better Java code organized by category. Many of these ideas will let you write more robust classes that better cooperate with built-in Java APIs. Many of the tips make use of software patterns and demonstrate an up-to-the-minute sense of what works best in today's design. Each tip is clearly introduced and explained with code snippets used to demonstrate each programming principle.
Early sections on creating and destroying objects show you ways to make better use of resources, including how to avoid duplicate objects. Next comes an absolutely indispensable guide to implementing "required" methods for custom classes. This material will help you write new classes that cooperate with old ones (with advice on implementing essential requirements like the equals() and hashCode() methods).
The author has a lot to say about class design, whether using inheritance or composition. Tips on designing methods show you how to create understandable, maintainable, and robust classes that can be easily reused by others on your team. Sections on mapping C code (like structures, unions, and enumerated types) onto Java will help C programmers bring their existing skills to Sun's new language. Later sections delve into some general programming tips, like using exceptions effectively. The book closes with advice on using threads and synchronization techniques, plus some worthwhile advice on object serialization.
Whatever your level of Java knowledge, this title can make you a more effective programmer. Wisely written, yet never pompous or doctrinaire, the author has succeeded in packaging some really valuable nuggets of advice into a concise and very accessible guidebook that arguably deserves a place on most any developer's bookshelf. --Richard Dragan
Topics covered:
Best practices and tips for Java
Creating and destroying objects (static factory methods, singletons, avoiding duplicate objects and finalizers)
Required methods for custom classes (overriding equals(), hashCode(), toString(), clone(), and compareTo() properly)
Hints for class and interface design (minimizing class and member accessibility, immutability, composition versus inheritance, interfaces versus abstract classes, preventing subclassing, static versus nonstatic classes)
C constructs in Java (structures, unions, enumerated types, and function pointers in Java)
Tips for designing methods (parameter validation, defensive copies, method signatures, method overloading, zero-length arrays, hints for Javadoc comments)
General programming advice (local variable scope, using Java API libraries, avoiding float and double for exact comparisons, when to avoid strings, string concatenation, interfaces and reflection, avoid native methods, optimizing hints, naming conventions)
Programming with exceptions (checked versus run-time exceptions, standard exceptions, documenting exceptions, failure-capture information, failure atomicity)
Threading and multitasking (synchronization and scheduling hints, thread safety, avoiding thread groups)
Serialization (when to implement Serializable, the readObject(), and readResolve() methods)
Joshua Bloch is chief Java architect at Google and a Jolt Award winner. He was previously a distinguished engineer at Sun Microsystems and a senior systems designer at Transarc. Bloch led the design and implementation of numerous Java platform features, including JDK 5.0 language enhancements and the award-winning Java Collections Framework. He coauthored Java™ Puzzlers (Addison-Wesley, 2005) and Java™ Concurrency in Practice (Addison-Wesley, 2006).

評分字字珠璣,讀過之後頓時覺得自己的程序韆瘡百孔,每一頁都有巧妙無比但又實用的技巧與方法。必定要反復過目的經典
評分Very practical technique to use Java.
評分很經典的實例代碼,但序列化那章好難,再找中文版的看一下
評分後麵兩百頁開始用瀏覽的方式閱讀,並且略過瞭枚舉和聲明式的部分以及部分泛型的內容。

評分个人认为这本书和《Thinking in java》一样,并不适合刚入门JAVA的人。它是一本进阶教程,里面的多线程或者设计模式,是需要一定的功力才能够理解作者所举的示例的。每个示例解释得恰到好处,可以作为实际开发的指导原则了吧,若有一些开发经验或者将作者所举的原则应用到实际...
