This comprehensive guide shows you how to master the most important
changes to Java since it was first released. Generics and the greatly
expanded collection libraries have tremendously increased the power of
Java 5 and Java 6. But they have also confused many developers who
haven't known how to take advantage of these new features.

Java Generics and Collections covers everything from the most
basic uses of generics to the strangest corner cases. It teaches you
everything you need to know about the collections libraries, so you'll
always know which collection is appropriate for any given task, and
how to use it.

Topics covered include:

  • Fundamentals of generics: type parameters and generic methods

  • Other new features: boxing and unboxing, foreach loops, varargs

  • Subtyping and wildcards

  • Evolution not revolution: generic libraries with legacy clients and
    generic clients with legacy libraries

  • Generics and reflection

  • Design patterns for generics

  • Sets, Queues, Lists, Maps, and their implementations

  • Concurrent programming and thread safety with collections

  • Performance implications of different collections

Generics and the new collection libraries they inspired take Java to a
new level. If you want to take your software development practice to
a new level, this book is essential reading.

Philip Wadler is Professor of Theoretical Computer Science at the
University of Edinburgh, where his research focuses on the design of
programming languages. He is a co-designer of GJ, work that
became the basis for generics in Sun's Java 5.0.

Maurice Naftalin is Technical Director at Morningside Light Ltd., a software consultancy in the United Kingdom. He has most recently served as an architect and mentor at NSB Retail Systems plc, and as the leader of the client development team of a major UK government social service system.

"A brilliant exposition of generics. By far the best book on the
topic, it provides a crystal clear tutorial that starts with the
basics and ends leaving the reader with a deep understanding of both
the use and design of generics."

Gilad Bracha, Java Generics Lead, Sun Microsystems

This book, written by one of the designers of generics, is a thorough explanation of how to use generics, and particularly, the effect this facility has on the way developers use collections.

    Do you wish to process lists? If you do, then this book is for you. Authors Maurice Naftalin and Philip Wadler, have done an outstanding job of writing a book that shows you how to master the most important changes to Java since it was first released. Naftalin and Wadler, begin with an overview of generics and other new features in Java 5. Then, the authors review how subtyping works and explain how wildcards let you use subtyping in connection with generics. Next, they describe how generics works with the Comparable interface, which requires a notion of bounds on type variables. They also look at how generics work with various declarations. The authors continue by explaining how to evolve legacy code to exploit generics. Then, they explain how the same design that leads to ease of evolution also necessarily leads to a few rough edges in the treatment of casts, exceptions and arrays. Next, they explain new features that relate generics and reflection. The authors also give advice on how to use generics effectively in practical coding. They continue by looking at how generics affect well known design patterns. Then, the authors give an overview of the Framework and then look in detail at each of the main interfaces and the standard implementation of them. Finally, the authors look at the special-purpose implementation and generic algorithms provided in the Collections class. This most excellent book covers everything from the most basic uses of generics to the strangest collections cases. Perhaps more importantly, this book shows you everything you need to know about the collections libraries!
