Core Java, Volume I: Fundamentals, 13th Edition (Early Release June, 2024) 1

The Classic Guide to the Java Programming Language--Fully Updated through Java 21 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. Written for experienced programmers looking for in-depth coverage of the Java language and platform, this revised and updated edition continues to be the first choice for serious programmers. The carefully crafted sample programs demonstrate almost every language and library feature, as well as the newest capabilities introduced in Java 21. The examples 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. This first of two volumes offers a detailed treatment of fundamental Java programming topics, including object-oriented programming, reflection and proxies, interfaces and inner classes, exception handling, generics, collections, lambda expressions, concurrency, annotations, and the Java Platform Module System. Master foundational techniques, idioms, and best practices for writing superior Java code Leverage the power of interfaces, lambda expressions, and inner classes Take advantage of sealed class hierarchies and pattern matching for processing structured data 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 Fully utilize multicore processors with Java's powerful concurrency model See Core Java, Volume II: Advanced Features, Thirteenth Edition, for coverage of Java 21 enterprise features, including detailed discussions of networking, security, internationalization, and advanced UI programming.
