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)

这样一本书本该早就读了,然而最近才看完。看完觉得对于一些编程规则深层的原理有了一些认识。之前我只是知道这些口口相传的规则,却不知道为什么,在这本书中找到了一些答案。书中涉及到了java编程方方面面的规则,包括类、接口、创建对象、类中的函数、函数的参数、异常、并...

所以趕緊出1.8的啊

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
