The Definitive Guide to Java Platform Best Practices—Updated for Java 7, 8, and 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 3rd 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 interface, java.time, and the convenience factory methods for collections
Since this Jolt-award winning classic was last updated in 2008, the Java programming environment has changed dramatically. Java 7 and Java 8 introduced new features and functions including, forEach() method in Iterable interface, default and static methods in Interfaces, Functional Interfaces and Lambda Expressions, Java Stream API for Bulk Data Operations on Collections, Java Time API, Collection API improvements, Concurrency API improvements, and Java IO improvements.
In this new edition of Effective Java, Bloch explores new design patterns and language idioms that have been introduced since the second edition was released in 2008 shortly after Java SE6, including Lambda, streams, generics and collections, as well as selected Java 9 features.
As in previous editions, each chapter consists of several “items” presented in the form of a short, standalone 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.
- Updated techniques and best practices on classic topics, including objects, classes, libraries, methods, and serialization
- How to avoid the traps and pitfalls of commonly misunderstood subtleties of the language
- Focus on the language and its most fundamental libraries: java.lang, java.util, and, to a lesser extent, java.util.concurrent and java.io
