很有诚意的一本书,适用于中级 Java 用户,算是 JLS 和设计模式的融合。不喜欢之一是这本书可以再精简一些;二是书中提到的很多问题更多是 Java 语言本身的,在后来的语言里已经被考虑到了,所以读起来很是鸡肋
评分字字珠玑,读过之后顿时觉得自己的程序千疮百孔,每一页都有巧妙无比但又实用的技巧与方法。必定要反复过目的经典
评分第二版,更厚了.
评分大部分都是精华,废话很少
评分JLS最佳注解
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).
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)
坐在那里看了一个小时,看的心浮气躁,完全看不下去任何内容。一个小时过去了连一个章节都没看完。也可能是因为没带笔,直接看感觉特别烦躁。看来看去只感觉,这本书在讲什么,这段话在讲什么?估计我修炼还不到家。我先看看别的吧,提高提高自己技术再来看好了,毕竟这本书评...
评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...
评分java书籍如core Java经常分两册,上册为基础fundmental,下册为advanced。上册讲编程的基本概念,下册谈被升级的概念(如泛型对于Object,try是某种不判断的if,并发是循环的横向扩展,集合是某种高级的数组等等)。这类书给人的感觉是概念的任意组合,正交化,什么都可以...
评分首先声明,这本书的中文翻译大体上还是过得去的,大方向上没问题。 ----------------------------分割线---------------------------- 1. p129 翻译:Java的枚举类型是功能十分齐全的类,功能比其他语言中的对等物要更强大得多,Java的枚举本质上是int值。 原文:Java's enum ...
评分身为一个以Java为生的Coder,到现在才看这本书,说起来多少有点惭愧。买了中文版,看了几页后实在是看不懂,完全不知所云,没办法,只好看英文版的,于是历时一个月,看得我欲仙欲死,生不如死。。。不过,经典就是经典,收获良多,强烈推荐!
