Core Java, Volume I: Fundamentals, 13th Edition (Early Release) 1

Whatever version of Java you are using, Core Java, Volume I: Fundamentals, Thirteenth Edition, will help you achieve a deep and practical understanding of the language and APIs. With hundreds of realistic examples, Java Champion Cay S. Horstmann demonstrates the most powerful and effective ways to get the job done. The book that you are reading right now is the first volume of the thirteenth edition of Core Java. Each edition closely followed a release of the Java Development Kit, and each time, I rewrote the book to take advantage of the newest Java features. This edition has been updated to reflect the features of Java 21. As with the previous editions, this book still targets serious programmers who want to put Java to work on real projects. I think of you, the reader, as a programmer with a solid background in a programming language other than Java. I assume that you don't like books filled with toy examples (such as toasters, zoo animals, or "nervous text"). You won't find any of these in the book. My goal is to enable you to fully understand the Java language and library, not to give you an illusion of understanding. In this book you will find lots of sample code demonstrating almost every language and library feature. The sample programs are purposefully simple to focus on the major points, but, for the most part, they aren't fake and they don't cut corners. They should make good starting points for your own code. I assume you are willing, even eager, to learn about all the features that the Java language puts at your disposal. In this volume, you will find a detailed treatment of: • Object-oriented programming • Reflection and proxies • Interfaces and inner classes • Exception handling • Generic programming • The collections framework • Concurrency • Annotations • The Java platform module system With the explosive growth of the Java class library, a one-volume treatment of all the features of Java that serious programmers need to know is simply not possible. Hence, the book is broken up into two volumes. This first volume concentrates on the fundamental concepts of the Java language. The second volume, Core Java, Volume II: Advanced Features, goes further into the most important libraries. The #1 Java Guide for Serious Programmers: Fully Updated through Java 17 "This is the definitive reference and instructional work for Java and the Java ecosystem." ---Andrew Binstock, Java Magazine Core Java, Volume I: Fundamentals, Twelfth Edition, is the definitive guide to writing robust, maintainable code. Whatever version of Java you are using---up to and including Java 17---this book will help you achieve a deep and practical understanding of the language and APIs. With hundreds of realistic examples, Cay S. Horstmann reveals the most powerful and effective ways to get the job done. This book is written for readers with prior programming experience who are looking for in-depth coverage of the Java language and platform. You'll learn about all language features in detail, including the recent improvements in Java 17. The applied chapters and code examples cover the most up-to-date capabilities of the vast Java library. For 25 years, Core Java has prepared serious programmers for serious Java programming. This first of two volumes offers in-depth coverage of fundamental Java programming, including object-oriented programming, generics, collections, lambda expressions, concurrency, and functional programming. Classic material for Swing UI programming is included for those who need it. This edition's new content covers text blocks, switch enhancements, records, pattern matching for instanceof, sealed classes, and more. Master foundational techniques, idioms, and best practices for writing superior Java code Leverage the power of interfaces, lambda expressions, and inner classes Harden programs through effective exception handling and debugging Write safer, more reusable code with generic programming Improve performance and efficiency with Java's standard collections Explore simple programs with JShell and assemble complex programs with archives and modules Build cross-platform GUIs with the Swing toolkit Fully utilize multicore processors with Java's powerful concurrency model See Core Java, Volume II: Advanced Features, Twelfth Edition (ISBN: 978-0-13-787107-0), for expert coverage of Java 17 enterprise features, the module system, annotations, networking, security, and advanced UI programming.
