内容简介:
The Definitive Guide to Java Platform Best Practices—Updated for Java 9
Java has changed dramatically since the previous edition of Effective Java was published shortly after the release of Java 6. This Jolt award-winning classic has now been thoroughly updated to take full advantage of the latest language and library features. The support in modern Java for multiple paradigms increases the need for specific best-practices advice, and this book delivers.
As in previous editions, each chapter of Effective Java, Third Edition, consists of several “items,” each presented in the form of a short, stand-alone essay that provides specific advice, insight into Java platform subtleties, and updated code examples. The comprehensive descriptions and explanations for each item illuminate what to do, what not to do, and why.
The third edition covers language and library features added in Java 7, 8, and 9, including the functional programming constructs that were added to its object-oriented roots. Many new items have been added, including a chapter devoted to lambdas and streams.
New coverage includes
Functional interfaces, lambda expressions, method references, and streams
Default and static methods in interfaces
Type inference, including the diamond operator for generic types
The @SafeVarargs annotation
The try-with-resources statement
New library features such as the Optional<T> interface, java.time, and the convenience factory methods for collections

原文摘录:
例如，构造器 BigInteger(int, int, Random)会返回一个为可能素数(probable prime)的 BigInteger， 但如果用一个名为 BigInteger.probablePrime 的静态工厂方法来表示，效果会更好。 (查看原文)

大多数程序员都不需要这个方法（指枚举的ordinal方法），他是设计成用于像EnumSet和EnumMap这种基于枚举的通用数据结构的，除非你在编写的是这类数据结构，否则最好完全避免使用ordinal方法。 (查看原文)
