Java Generics and Collections has been the go-to guide to generics for more than a decade. This second edition covers Java 21, providing a clear guide to generics from their most common uses to the strangest corner cases, giving you everything you need to know to use and write generic APIs effectively. It covers the collections library thoroughly, so you'll always know how and when to use each collection for any given task. And it explains stream processing, so you'll know which model to use and how they interoperate to get the best out of the platform library.

This indispensable guide covers:

Fundamentals of generics: type parameters and generic methods
Subtyping and wildcards
Generics and reflection
Design patterns for generics
Sets, queues, lists, maps, and their implementations
Concurrent programming and thread safety with collections
Performance of different collection implementations
Best practices for using and extending the Java collections framework
Design philosophy and comparison with other collections libraries

Intended Audience:
This book is intended for everyone who knows something about Java, and would like to find out more. It’s not a Java tutorial, so we assume knowledge of basic Java concepts like classes, static and instance methods, and so on. We use the syntax of Java 21, but most syntax features associated specifically with generics are explained in the text. If you are having difficulty understanding the syntax of a particular code sample, you may find that your IDE can offer helpful refactoring suggestions that will clarify its purpose. We assume very basic knowledge of the Collections API. If you have written any programs using ArrayList or HashSet, you should have no difficulty. When discussing the behavior of particular collections classes and methods, we often refer to the Javadoc.
