Core Java, Volume I

The Classic Guide to the Java Programming Language--Fully Updated through Java 25

Whatever version of Java you are using, Core Java, Volume I: Fundamentals, Fourteenth 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 25. 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 compact compilation units, instance main methods, and module imports
• Assemble complex programs with archives and modules
• Effectively utilize Java's powerful concurrency model, using platform and virtual thread

This is the definitive reference and instructional work for Java and the Java ecosystem."
