Covers everything from the basic uses of generics to the strangest corner cases. This book covers: fundamentals of generics: type parameters and generic methods; boxing and unboxing, foreach loops; subtyping and wildcards; evolution not revolution; Design patterns for generics; Sets, Queues, Lists, Maps, and their implementations; and more.
Focusing on generics and collections in Java, this second edition addresses Java 21 and serves as a comprehensive resource for effectively using and writing generic APIs. It thoroughly explores the collections library, detailing when and how to utilize each type for various tasks. Additionally, it delves into stream processing, explaining the interaction between different models to optimize performance with the platform library. This guide is essential for mastering both common applications and complex scenarios in Java programming.
