The core idea of this book is that object- oriented technology is a generic technology whose various technical aspects can be presented in a unified and consistent framework. This applies to both practical and formal aspects of object-oriented technology. Course tested in a variety of object-oriented courses, numerous examples, figures and exercises are presented in each chapter. The approach in this book is based on typed technologies, and the core notions fit mainstream object-oriented languages such as Java and C#. The book promotes object-oriented constraints (assertions), their specification and verification. Object-oriented constraints apply to specification and verification of object-oriented programs, specification of the object-oriented platform, more advanced concurrent models, database integrity constraints and object-oriented transactions, their specification and verification.

Tackle some of the biggest challenges in learning Functional Programming with this modern, up-to-date approach. Objects First with Java: A Practical Introduction, Global Edition, 6th Edition by Barnes and Koelling is an introduction to object-oriented programming, examining various programming concepts from a software engineering perspective. Ideal for beginners but also more advanced students and professional programmers, the book begins with introductory chapters for students without any programming experience, with later chapters more suitable for advanced or professional programmers. This latest edition goes beyond just adding the new language constructs of Java 8. The book's exploration of this new language demonstrates a renaissance of new functional ideas and techniques in modern programming, taking advantage of the boost in their popularity, in line with the new computing hardware available and the changing nature of current issues. Key features include: Extensive use of the Java programming language and BlueJ - the Java interactive development environment. Clear visualisation of BlueJ's classes and objects, allows you to gain a much better understanding of the differences than simply reading source code. Chapters are ordered by software development concepts instead of language features, like in traditional textbooks. Functional programming has become an essential part of the field. This industry-leading text will take you from the first steps of learning objects to more sophisticated concepts and will help you explore and master the mechanics of running a program successfully.

Learn and understand Erlang and Elixir and develop a working knowledge of the concepts of functional programming that underpin them. This book takes the author's experience of taking on a project that required functional programming and real-time systems, breaks it down, and organizes it. You will get the necessary knowledge about differences to the languages you know, where to start, and where to go next. Have you been told by your customer or manager that they heard good things about Erlang, you should use it for the next project? Never had to deal with functional programming or real-time systems? In 2014, the author, Wolfgang Loder, developed a repository for digital assets that had to deliver those assets in binary form quickly and reliably, being able to deal with at least hundreds of requests per second. Since he could decide the architecture and software stack of the solution, he immediately thought of Erlang and its libraries and started to evaluate this option. It was not long after that he discovered Elixir, which sits on top of the Erlang virtual machine and has features more palatable for non-functional programmers, although it is a functional programming language itself. Erlang and Elixir for Imperative Programmers gives you a basis for deciding whether the effort is viable for your next project. This book is partly a tale of the author's own experience and partly a description of the bigger and more subtle differences between Erlang/Elixir and languages such as C++, Java, and C#. What You'll Learn Discover functional programming, Erlang, and Elixir Work on service design and service features Set up your environment: deployment, development, and production Implement the service including public interface, asset processing, and deployment Use the patterns and concepts found in Erlang including type creation concepts and code structuring. Who This Book Is For Experienced and savvy programmers, coders, and developers new to Erlang and Elixir.

Chapter 10 dives into Java's XML support by first presenting an introduction to XML (including DTDs and schemas). It next explores the SAX, DOM, StAX, XPath, and XSLT APIs. It even briefly touches on the Validation API. While exploring XPath, you encounter namespace contexts, extension functions and function resolvers, and variables and variable resolvers. Chapter 11 introduces you to Java's support for SOAP-based and RESTful web services.In addition to providing you with the basics of these web service categories, Chapter 11 presents some advanced topics, such as working with the SAAJ API to communicate with a SOAP-based web service without having to rely on JAX-WS. You will appreciate having learned about XML in Chapter 10 before diving into this chapter. Chapter 12 helps you put to use some of the knowledge you've gathered in previous chapters by showing you how to use Java to write an Android app's source code. This chapter introduces you to Android, discusses its architecture, shows you how to install necessary tools, and develops a simple app. Appendix A presents the solutions to the programming exercises that appear near the end of Chapters 1 through 12. Appendix B introduces you to Java's Scripting API along with Java 7's support for dynamically typed languages. Appendix C introduces you to additional APIs and architecture topics: Accessibility, ByteArrayOutputStream and ByteArrayInputStream, classloaders, Console, Desktop, Drag and Drop, Dynamic Layout, Extension Mechanism and ServiceLoader, File Partition-Space, File Permissions, Formatter, Image I/O, Internationalization, Java Native Interface, NetworkInterface and InterfaceAddress, New I/O (including NIO.2), PipedOutputStream and PipedInputStream, Preferences, Scanner, Security, Smart Card, Splash Screen, Stream Tokenizer, StringTokenizer, SwingWorker, System Tray, Timer and TimerTask, Tools and the Compiler API, Translucent and Shaped Window, and XML Digital Signature. Appendix D presents a gallery of significant applications that demonstrate various aspects of Java. Unfortunately, there are limits to how much knowledge can be crammed into a print book. For this reason, Appendixes A, B, C, and D are not included in this book's pages. Instead, these appendixes are freely distributed as PDF files. Appendixes A and B are bundled with the book's associated code file at the Apress website (http: //www.apress.com). Appendixes C and D are bundled with their respective code files on my TutorTutor.ca website at http: //tutortutor.ca/cgi-bin/makepage.cgi?/books/bj7. Appendixes C and D are living documents in that I'll occasionally add new material to them. For example, I plan to expand Appendix C by also covering Java Naming and Directory Interface, Java Sound, Remote Method Invocation and Corba, Robot, Runtime and Process, Swing Timer, and many other APIs/architecture topics (including a complete tour of Swing components). Of course, it will take time to write about these topics so don't expect all of them to appear at once -- they will slowly emerge in coming months (although smaller topics such as Robot will emerge much faster). What you'll learn * The

Domain-Driven Design (DDD) is a software development philosophy for tackling complex systems. Software is based around a model of the business domain in code to enable developers and business users to talk about problems in a single language. DDD is attracting new adoptees as .NET developers continue to mature and seek out best practices for developing enterprise level applications.This book is the first to present the philosophy of DDD in a down to earth practical manner for experienced developers. It shows developers how the concepts of DDD can be applied to their applications with real world examples. Unlike other books on the subject, it is packed with patterns, code examples and case studies that help to cement the theory of DDD.After introducing readers to DDD and its application (complete with development best practices and patterns), it goes on to explain Command, Query, Responsibility Segregation Architecture (CQRS), an architectural pattern that can be used to implement a DDD design methodology. Finally, a case study is included to show DDD, CQRS, and Messaging Pub/Sub architecture in the context of a real set of enterprise applications.The book includes: An introduction to the philosophy of Domain-Driven Design (DDD)Command, Query, Responsibility Segregation Architecture (CQRS)DDD Best practices for modeling patternsPublish/Subscribe Messaging Architecture for Bounded Contexts Throughout, the book gives the reader masses of code and examples of the concepts that other books have theorized about.

LINQ is the part of the .NET Framework that provides a generic approach to querying data from different data sources. It has quickly become the next must-have skill for .NET developers. Pro LINQ: Language Integrated Query in C# 2010 is all about code. Literally, this book starts with code and ends with code. Most books show the simplest examples of how to use a method, but they so rarely show how to use the more complex prototypes. This book is different. Demonstrating the overwhelming majority of LINQ operators and prototypes, it is a veritable treasury of LINQ examples.

Rather than obscure the relevant LINQ principles in code examples by focusing on a demonstration application you have no interest in writing, this book cuts right to the chase of each LINQ operator, method, or class. However, where complexity is necessary to truly demonstrate an issue, the examples are right there in the thick of it. For example, code samples demonstrating how to handle concurrency conflicts actually create concurrency conflicts so you can step through the code and see them unfold.

Face it, most technical books, while informative, are dull. LINQ need not be dull. Written with a sense of humor, this book will attempt to entertain you on your journey through the wonderland of LINQ and C# 2010. What you'll learn How to leverage all the new LINQ relevant C# 2008 language features including extension methods, lambda expressions, anonymous data types, and partial methods. How to use LINQ to Objects to query in-memory data collections such as arrays, ArrayLists, and Lists to retrieve the data you want. Why some queries are deferred, how a deferred query can bite you, and how you can make deferred queries work for you. How to use LINQ to XML to revolutionize your creation, manipulation, and searching of XML data. How to query DataSets with LINQ to DataSet so you can coexist with legacy code and use LINQ to query databases other than SQL Server. How to query Databases with LINQ to SQL, write your own entity classes, and understand how to handle concurrency conflicts. Who this book is for
