Learn how to be more productive with Scala, a new multi-paradigm language for the Java Virtual Machine (JVM) that integrates features of both object-oriented and functional programming. With this book, you'll discover why Scala is ideal for highly scalable, component-based applications that support concurrency and distribution. Programming Scala clearly explains the advantages of Scala as a JVM language. You'll learn how to leverage the wealth of Java class libraries to meet the practical needs of enterprise and Internet projects more easily. Packed with code examples, this book provides useful information on Scala's command-line tools, third-party tools, libraries, and available language-aware plugins for editors and IDEs. Learn how Scala's succinct and flexible code helps you program faster Discover the notable improvements Scala offers over Java's object model Get a concise overview of functional programming, and learn how Scala's support for it offers a better approach to concurrency Know how to use mixin composition with traits, pattern matching, concurrency with Actors, and other essential features Take advantage of Scala's built-in support for XML Learn how to develop domain-specific languages Understand the basics for designing test-driven Scala applications

Need to move a relational database application to Hadoop? This comprehensive guide introduces you to Apache Hive, Hadoop’s data warehouse infrastructure. You’ll quickly learn how to use Hive’s SQL dialect—HiveQL—to summarize, query, and analyze large datasets stored in Hadoop’s distributed filesystem. This example-driven guide shows you how to set up and configure Hive in your environment, provides a detailed overview of Hadoop and MapReduce, and demonstrates how Hive works within the Hadoop ecosystem. You’ll also find real-world case studies that describe how companies have used Hive to solve unique problems involving petabytes of data. Use Hive to create, alter, and drop databases, tables, views, functions, and indexes Customize data formats and storage options, from files to external databases Load and extract data from tables—and use queries, grouping, filtering, joining, and other conventional query methods Gain best practices for creating user defined functions (UDFs) Learn Hive patterns you should use and anti-patterns you should avoid Integrate Hive with other data processing programs Use storage handlers for NoSQL databases and other datastores Learn the pros and cons of running Hive on Amazon’s Elastic MapReduce

Get up to speed on Scala--the JVM, JavaScript, and natively compiled language that offers all the benefits of functional programming, a modern object model, and an advanced type system. Packed with code examples, this comprehensive book shows you how to be productive with the language and ecosystem right away. You'll learn why Scala is ideal for building today's highly scalable, data-centric applications while maximizing developer productivity. While Java remains popular and Kotlin has become popular, Scala hasn't been sitting still. This third edition covers the new features in Scala 3 with updates throughout the book. Programming Scala is ideal for beginning to advanced developers who want a complete understanding of Scala's design philosophy and features with a thoroughly practical focus. Program faster with Scala's succinct and flexible syntax Dive into basic and advanced functional programming techniques Build killer big data and distributed apps using Scala's functional combinators and tools like Spark and Akka Create concise solutions to challenging design problems with the sophisticated type system, mixin composition with traits, pattern matching, and more

Software development today is embracing functional programming (FP), whether it's for writing concurrent programs or for managing Big Data. Where does that leave Java developers? This concise book offers a pragmatic, approachable introduction to FP for Java developers or anyone who uses an object-oriented language. Dean Wampler, Java expert and author of Programming Scala (O'Reilly), shows you how to apply FP principles such as immutability, avoidance of side-effects, and higher-order functions to your Java code. Each chapter provides exercises to help you practice what you've learned. Once you grasp the benefits of functional programming, you’ll discover that it improves all of the code you write. Learn basic FP principles and apply them to object-oriented programming Discover how FP is more concise and modular than OOP Get useful FP lessons for your Java type design—such as avoiding nulls Design data structures and algorithms using functional programming principles Write concurrent programs using the Actor model and software transactional memory Use functional libraries and frameworks for Java—and learn where to go next to deepen your functional programming skills

Tools for Better Concurrency, Abstraction, and Agility

Functional Programming for Java Developers

O desenvolvimento de software atualmente está encampando a programação funcional (FP - Functional Programming), seja para escrever programas concorrentes, seja para gerenciar grandes volumes de dados. Onde isso deixa os desenvolvedores Java? Este livro conciso oferece uma introdução pragmática e acessível a FP para desenvolvedores Java ou qualquer pessoa que use uma linguagem orientada a objetos. Dean Wampler, especialista em Java e autor de Programming Scala (O'Reilly), mostra a você como aplicar princípios de FP como imutabilidade, evitar efeitos colaterais e funções de ordem mais alta no seu código em Java. Cada capítulo fornece exercícios para auxiliá-lo a praticar o que aprendeu. Assim que você entender os benefícios da programação funcional, descobrirá que ela melhora todo o código que você escreve. •Aprenda os princípios básicos da FP e aplique-os à programação orientada a objetos •Descubra como a FP é mais concisa e modular que a OOP •Aprenda lições úteis de FP para o seu projeto de tipos em Java – como, por exemplo, evitar nulos •Projete estruturas de dados e algoritmos usando princípios de programação funcional •Escreva programas concorrentes usando o modelo Actor e software transactional memory •Use bibliotecas funcionais e frameworks para Java – e aprenda aonde ir a seguir para aprofundar seu conhecimento em programação funcional

Ferramentas para Melhor Concorrência, Abstração e Agilidade

Programação Funcional para Desenvolvedores Java

Sie ist elegant, schlank, modern und flexibel: Die Rede ist von Scala, der neuen Programmiersprache für die Java Virtual Machine (JVM). Sie vereint die Vorzüge funktionaler und objektorientierter Programmierung, ist typsicherer als Java, lässt sich nahtlos in die Java-Welt integrieren – und eine in Scala entwickelte Anwendung benötigt oft nur einen Bruchteil der Codezeilen ihres Java-Pendants. Kein Wunder, dass immer mehr Firmen, deren große, geschäftskritische Anwendungen auf Java basieren, auf Scala umsteigen, um ihre Produktivität und die Skalierbarkeit ihrer Software zu erhöhen. Das wollen Sie auch? Dann lassen Sie sich von den Scala-Profis Dean Wampler und Alex Payne zeigen, wie es geht. Ihre Werkzeugkiste: Schon bevor Sie loslegen, sind Sie weiter, als Sie denken: Sie können Ihre Java-Programme weiter verwenden, Java-Bibliotheken nutzen, Java von Scala aus aufrufen und Scala von Java aus. Auch Ihre bevorzugten Entwicklungswerkzeuge wie NetBeans, IntelliJ IDEA oder Eclipse stehen Ihnen weiter zur Verfügung, dazu Kommandozeilen-Tools, Plugins für Editoren, Werkzeuge von Drittanbietern – und natürlich Ihre Programmiererfahrung. In Programmieren mit Scala erfahren Sie, wie Sie sich all das zunutze machen. Das Hybridmodell: Die Paradigmen "funktional" und "objektorientiert" sind keine Gegensätze, sondern ergänzen sich unter dem Scala-Dach zu einem sehr produktiven Ganzen. Nutzen Sie die Vorteile funktionaler Programmierung, wann immer sich das anbietet – und seien Sie so frei, auf die guten alten Seiteneffekte zu bauen, wenn Sie das für nötig halten. Futter für die Profis: Skalierbare Nebenläufigkeit mit Aktoren, Aufzucht und Pflege von XML mit Scala, Domainspezifische Sprachen, Tipps zum richtigen Anwendungsdesign – das sind nur ein paar der fortgeschrittenen Themen, in die Sie mit den beiden Autoren eintauchen. Danach sind Sie auch Profi im Programmieren mit Scala.
