Groovy preserves the Java semantics and extends the JDK to give you true dynamic language capabilities. "Programming Groovy 2" will help you, the experienced Java developer, learn and take advantage of the latest version of this rich dynamic language. You'll go from the basics of Groovy to the latest advances in the language, including options for type checking, tail-call and memoization optimizations, compile time metaprogramming, and fluent interfaces to create DSLs. You don't have to leave the rich Java Platform to take advantage of Groovy. Groovy preserves Java's semantics and extends the JDK, so programming in Groovy feels like the Java language has been augmented; it's like working with a lighter, more elegant Java. If you're an experienced Java developer who wants to learn how Groovy works, you'll find exactly what you need in this book. You'll start with the fundamentals of programming in Groovy and how it works with Java, and then you'll explore advanced concepts such as unit testing with mock objects, using Builders, working with databases and XML, and creating DSLs. You'll master Groovy's powerful yet complex run-time and compile-time metaprogramming features. Much has evolved in the Groovy language since the publication of the first edition of "Programming Groovy." "Programming Groovy 2" will help you learn and apply Groovy's new features. Creating DSLs is easier now, and Groovy's already-powerful metaprogramming facilities have improved even more. You'll see how to work with closures, including tail call optimization and memoization. The book also covers Groovy's new static compilation feature. Whether you're learning the basics of the language or interested in getting proficient with the new features, "Programming Groovy 2" has you covered.What You Need To work on the examples in the book you need Groovy 2.0.5 and Java JDK 5 or higher.

Get a grounding in polymorphism and other fundamental aspects of object-oriented program design and implementation, and learn a subset of design patterns that any practicing Java professional simply must know in today's job climate. Java Program Design presents program design principles to help practicing programmers up their game and remain relevant in the face of changing trends and an evolving language. The book enhances the traditional design patterns with Java's new functional programming features, such as functional interfaces and lambda expressions. The result is a fresh treatment of design patterns that expands their power and applicability, and reflects current best practice. The book examines some well-designed classes from the Java class library, using them to illustrate the various object-oriented principles and patterns under discussion. Not only does this approach provide good, practical examples, but you will learn useful library classes you might not otherwise know about. The design of a simplified banking program is introduced in chapter 1 in a non-object-oriented incarnation and the example is carried through all chapters. You can see the object orientation develop as various design principles are progressively applied throughout the book to produce a refined, fully object-oriented version of the program in the final chapter. What You'll Learn Create well-designed programs, and identify and improve poorly-designed ones Build a professional-level understanding of polymorphism and its use in Java interfaces and class hierarchies Apply classic design patterns to Java programming problems while respecting the modern features of the Java language Take advantage of classes from the Java library to facilitate the implementation of design patterns in your programs Who This Book Is For Java programmers who are comfortable writing non-object-oriented code and want a guided immersion into the world of object-oriented Java, and intermediate programmers interested in strengthening their foundational knowledge and taking their object-oriented skills to the next level. Even advanced programmers will discover interesting examples and insights in each chapter.

Your essential comparative approach to learning C++ and Java

Programming with Objects: A Comparative Presentation of Object-Oriented Programming with C++ and Java, a comparative presentation of object-oriented programming with two of the most popular programming languages of today, teaches vital skills and techniques for the Internet age. Based on highly successful courses taught by the author, this book answers the need for a comprehensive educational program on the subject of object-oriented programming. In a clear and accessible format, the author compares and contrasts both languages, from basic language constructs to how both languages are used in application-level programming, such as graphics programming, network programming, and database programming.

Since both C++ and Java were born out of the same language, C, learning these two languages together has several distinct advantages:

• Because they have much in common at the level of basic language structures, learning C++ and Java together saves time and facilitates the mastery of each
• Learning by contrast and comparison can be more efficient and enjoyable, allowing readers access to the strengths and weaknesses of both languages
• Learning to write a program in one language that corresponds to a given program in the other language enables students to tackle more difficult projects in either language
• Comparing similar concepts in the two languages leads to a deeper understanding of the concepts in both

Roughly the first half of the text is devoted to basic language issues. More advanced topics are detailed in the second half, including programming of graphical user interfaces, multithreading, network programming, and database programming.

Designed as a text for educational programs in advanced programming and as a reference for professionals implementing Web- and Internet-based applications, Programming with Objects: A Comparative Presentation of Object-Oriented Programming with C++ and Java is also recommended for programmers familiar with either language who wish to expand their programming skills.

This book concerns software design. Although many current discussions of scientific programming focus on scalable performance, this book focuses on scalable design. The authors analyze how the structure of a package determines its developmental complexity according to such measures as bug search times and documentation information content. The work presents arguments for why these issues impact solution cost and time more than does scalable performance. The final chapter explores the question of scalable execution and shows how scalable design relates to scalable execution. The book's focus is on program organization, which has received considerable attention in the broader software engineering community, where graphical description standards for modeling software structure and behavior have been developed by computer scientists. These discussions might be enriched by engineers who write scientific codes. This book aims to bring such scientific programmers into discussion with computer scientists. The authors do so by introducing object-oriented software design patterns in the context of scientific simulation.
