Java jest dziś językiem, który programiści wybierają najczęściej, gdy mają przed sobą skomplikowany projekt, wymagający najwyższej wydajności, jakości, bezpieczeństwa oraz integracji z innymi systemami. Rozwijany od blisko dwudziestolecia, język ten doczekał się wersji oznaczonej numerem 8. Ta edycja została wzbogacona o wiele nowości, m.in. o długo oczekiwane wyrażenia lambda. Jeżeli szukasz poręcznej książki, do której możesz sięgnąć w przypadku wątpliwości, to trafiłeś na doskonałą pozycję! Ta publikacja należy do popularnej serii „Leksykon kieszonkowy” i możesz mieć ją zawsze przy sobie. W środku znajdziesz konwencje nazw oraz podstawowe elementy języka. W kolejnych rozdziałach zdobędziesz wiedzę na temat typów prostych oraz programowania zorientowanego obiektowo. Ponadto zawarto tu przystępne omówienie wyrażeń lambda, współbieżności oraz zasad dostępu do plików i sieci. Java posiada rozbudowany mechanizm obsługi sytuacji wyjątkowych, który również został omówiony w tym podręczniku. Książka ta jest obowiązkową pozycją na półce każdego programisty języka Javy — jeśli chce on mieć zawsze pod ręką wiarygodne źródło informacji na temat tego języka. Materiał przedstawiony w książce pomaga również w przygotowaniach do egzaminu Oracle Certified Associate Java Programmer. Szybko odszukaj szczegóły dotyczące języka Java, na przykład konwencje nazw, typy, polecenia i bloki, programowanie zorientowane obiektowo. Poznaj informacje szczegółowe o platformie Java SE, między innymi podstawy programowania, zarządzanie pamięcią, współbieżność i typy generyczne. Przeglądaj informacje z zakresu podstawowych operacji wejścia-wyjścia, API NIO 2.0, frameworka kolekcji w Javie, a także API skryptowego Javy. Poznaj informacje dotyczące API Fluent, narzędzi opracowanych przez firmy trzecie oraz podstawy zunifikowanego języka modelowania (UML). „Wspaniale jest móc poznać wyrażenia lambda i operacje funkcjonalne, jak również inne nowe funkcje Javy przedstawione w kontekście platformy Java.” — Geertjan Wielenga, dyrektor produktu w grupie Oracle Developer zajmującej się środowiskiem IDE NetBeans

Writing concurrent and parallel programming applications is an integral skill for any Java programmer. Java 9 comes with a host of fantastic features, including significant performance improvements and new APIs.This book will take you through all the new APIs, showing you how to build parallel and multi-threaded applications. The book covers all the elements of the Java Concurrency API, with essential recipes that will help you take advantage of the exciting new capabilities.You will learn how to use parallel and reactive streams to process massive data sets. Next, you will move on to create streams and use all their intermediate and terminal operations to process big collections of data in a parallel and functional way.Further, you’ll discover a whole range of recipes for almost everything, such as thread management, synchronization, executors, parallel and reactive streams, and many more. At the end of the book, you will learn how to obtain information about the status of some of the most useful components of the Java Concurrency API and how to test concurrent applications using different tools.
Java 9 Data Structures and Algorithms. A step-by-step guide to data structures and algorithms
Debasish Ray Chawdhuri
Java 9 Data Structures and Algorithms covers classical, functional, and reactive data structures, giving you the ability to understand computational complexity, solve problems, and write efficient code. This book is based on the Zero Bug Bounce milestone of Java 9.We start off with the basics of algorithms and data structures, helping you understand the fundamentals and measure complexity. From here, we introduce you to concepts such as arrays, linked lists, as well as abstract data types such as stacks and queues. Next, we’ll take you through the basics of functional programming while making sure you get used to thinking recursively.We provide plenty of examples along the way to help you understand each concept. You will also get a clear picture of reactive programming, binary searches, sorting, search trees, undirected graphs, and a whole lot more!
Java 9 Dependency Injection. Write loosely coupled code with Spring 5 and Guice
Nilang Patel , Krunal Patel
Dependency Injection (DI) is a design pattern that allows us to remove the hard-coded dependencies and make our application loosely coupled, extendable, and maintainable. We can implement DI to move the dependency resolution from compile-time to runtime. This book will be your one stop guide to write loosely coupled code using the latest features of Java 9 with frameworks such as Spring 5 and Google Guice. We begin by explaining what DI is and teaching you about IoC containers. Then you’ll learn about object compositions and their role in DI. You’ll find out how to build a modular application and learn how to use DI to focus your efforts on the business logic unique to your application and let the framework handle the infrastructure work to put it all together. Moving on, you’ll gain knowledge of Java 9’s new features and modular framework and how DI works in Java 9. Next, we’ll explore Spring and Guice, the popular frameworks for DI. You’ll see how to define injection keys and configure them at the framework-specific level. After that, you’ll find out about the different types of scopes available in both popular frameworks. You’ll see how to manage dependency of cross-cutting concerns while writing applications through aspect-oriented programming.Towards the end, you’ll learn to integrate any third-party library in your DI-enabled application and explore common pitfalls and recommendations to build a solid application with the help of best practices, patterns, and anti-patterns in DI.
