Modern Java introduces major enhancements that impact the core Java technologies and APIs at the heart of the Java platform. Many old Java idioms are no longer needed, and new features and programming paradigms can make you far more effective. However, navigating these changes can be challenging. Core Java for the Impatient, Fourth Edition, is a complete yet concise guide that reflects all changes through Java SE 21, Oracle's latest Long-Term Support (LTS) release. Written by Cay S. Horstmann--author of the classic two-volume Core Java--this indispensable tutorial offers a faster, easier pathway for learning modern Java. Horstmann covers everything working developers need to know, including the powerful concepts of lambda expressions and streams, modern constructs such as records and sealed classes, and sophisticated concurrent programming techniques. Given the size and scope of Java 21, there's plenty to cover, but it's presented in small chunks organized for quick access and easy understanding, with plenty of practical insights and sample code to help you quickly apply all that's new. Test code as you create it with JShellImprove your object-oriented design with records and sealed classesEffectively use text blocks, switch expressions, and pattern matchingUnderstand functional programming with lambda expressionsStreamline and optimize data management with the Streams APIUse structured techniques, threadsafe data structures, and virtual threads for effective concurrent programmingWork with the modularized Java API and third-party modulesTake advantage of API improvements for working with collections, input/output, regular expressions, and processes Whether you're an experienced developer just getting started with modern Java, or have been programming with Java for years, this guide will help you write more robust, efficient, and secure Java code.

The Classic Guide to Advanced Java Programming: Fully Updated for Java 21 Core Java is the leading no-nonsense tutorial and reference for experienced programmers who want to write robust Java code for real-world applications. Now, Core Java, Volume II: Fundamentals, Thirteenth Edition, has been revised to cover the new features and enhancements in the Java 21 long-term support release. As always, all chapters have been completely updated, outdated material has been removed, and the new APIs are covered in detail. This volume focuses on the advanced topics that a programmer needs to know for professional software development and includes authoritative coverage of enterprise programming, networking, databases, security, internationalization, and native methods, as well as complete chapters on the Streams, XML, Date and Time, Scripting, and Compilation APIs. In addition, the chapters on Swing and Graphics cover techniques that are applicable to both client-side user interfaces and server-side generation of graphics and images. Cay S. Horstmann clearly explains sophisticated new features with depth and completeness and demonstrates how to use them to build professional-quality applications. Horstmann's thoroughly tested sample code reflects modern Java style and best practices. The examples are carefully crafted for easy understanding and maximum practical value, so you can rely on them to jump-start your own programs. Master advanced techniques, idioms, and best practices for writing reliable Java code Make the most of enhanced Java I/O APIs, object serialization, and regular expressions Connect to network services, harvest web data with the HTTP/2 client, and serve data with the built-in web server or implement your own server Process code via the Scripting and Compiler APIs Work with the Date and Time API, including recent refinements Leverage the Java security model, user authentication, and the security library's cryptographic functions Preview powerful new APIs for accessing "foreign" functions and memory "This is the definitive reference and instructional work for Java and the Java ecosystem." --Andrew Binstock, Java Magazine See Core Java, Volume I: Fundamentals, Thirteenth Edition, for expert coverage of Java programming fundamentals, including objects, generics, collections, lambda expressions, concurrency, and functional programming.

Scala 3--A Clear, Concise Guide Scala 3 is concise, consistent, flexible, robust, and efficient, but there's a lot to learn and navigating features and improvements can be challenging. Scala for the Impatient, Third Edition, is a complete yet concise guide that reflects the major enhancements of Scala 3, from improved syntax and revamped type system to powerful contextual abstractions. This indispensable tutorial offers a faster, easier pathway for learning today's Scala. Horstmann--author of the programming classic, Core Java--covers everything working developers need to know, focusing on hands-on solutions, not academic theory. Given the size and scope of Scala 3, there's plenty to cover but it's presented in small chunks organized for quick access and easy understanding, with plenty of practical insights and focused sample code. Get started quickly with Scala 3 interpreter, syntax, tools, and current usage Master core language features: functions, arrays, maps, tuples, packages, imports, exception handling, and more Design and build better object-oriented code with Scala 3 Use Scala for real-world programming tasks: working with files, regular expressions, and processes Work with higher-order functions and the powerful Scala collections library Create concurrent programs with Scala futures Understand the Scala type system, including revamped enums, intersection and union types, and enhanced type inference Use contextual abstractions to easily extend class hierarchies, enrich existing classes, perform automatic conversions, and elegantly hide tedious details Apply advanced "power tools" such as annotations and given values Discover how to "program with types," analyzing and generating types at compile time Get a taste of what's now possible with Scala macros If you're a Java, Python, C++, or C# programmer who's new to Scala or functional programming--or even if you've already used earlier versions of Scala--this guide will help you write code that's more robust, more efficient, and more secure.

Today, JavaScript is radically different and more powerful than ever. In an environment where user interfaces are increasingly web-based, it's become the "lingua franca” of the web browser. Frameworks such as Electron and platforms like AWS Lambda are extending its power even further. If you're moving to JavaScript, you need to learn modern JavaScript, but most guides still focus on legacy techniques. In Modern JavaScript for the Impatient, best-selling author Cay Horstmann offers a concise, complete, and practical introduction to today's JavaScript techniques and tools, and shows how to avoid pitfalls from the past. Horstmann shows students how to take full advantage of the Standard Library, modern JavaScript tools, asynchronous and web programming, and much more. Students will find especially valuable coverage of toolchains and frameworks, which often baffle JavaScript newcomers. As in Core Java® SE 9 for the Impatient, Horstmann covers plenty of ground, but he presents his techniques in small chunks organized for quick access and easy understanding. This is JavaScript for the projects your students are starting now - and those they'll be seeing tomorrow.
