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 usageMaster core language features: functions, arrays, maps, tuples, packages, imports, exception handling, and moreDesign and build better object-oriented code with Scala 3Use Scala for real-world programming tasks: working with files, regular expressions, and processesWork with higher-order functions and the powerful Scala collections libraryCreate concurrent programs with Scala futuresUnderstand the Scala type system, including revamped enums, intersection and union types, and enhanced type inferenceUse contextual abstractions to easily extend class hierarchies, enrich existing classes, perform automatic conversions, and elegantly hide tedious detailsApply advanced "power tools" such as annotations and given valuesDiscover how to "program with types," analyzing and generating types at compile timeGet 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.
