Java has quickly become one of the most important languages in programming, particularly for professional and enterprise-level projects. From its infancy as a language primarily used for web applets to its maturity through servlets, Enterprise JavaBeans, and database access, Java has become a complex and robust tool for today's developer.

"Hardcore Java" takes this language and breaks it apart, piece by piece, revealing the important secrets and tricks that will take you from a junior-level programmer to a seasoned and expert developer. You'll fly through the fundamentals and quickly find yourself learning about advanced memory management techniques, optimization and bytecode-level enhancements, and the techniques required to build lightning-fast GUIs. Throughout the book, you'll also master the art of writing and maintaining bulletproof and error-proof code, all while grasping the intricacies of the Java language.

"Hardcore Java" covers:

Use of the final keyword to optimize and protect your Java classes.

Complete and thorough coverage of all types of nested classes, including how to optimize anonymous and inner classes.

Detailed discussion of immutable objects, including unique tips on when to use them (and when not to).

Elimination of bugs through exception-handling management.

In-depth studies of constants, including their impact on the Java memory model.

The most thorough discussion of reflection in print, moving far beyond other books' "Hello World" coverage.

Construction and use of dynamic proxies, in both Java Standard and Enterprise editions.

Expansive coverage of weak references, including usage patterns and their role in garbage collection andmemory management.

"Hardcore Java" is an invaluable addition to every programmer's library, and even the most advanced developers will find themselves moving beyond their own conceptions into truly advanced applications of the language. Thousands of lines of code, heavily commented and easily runnable, illustrate each concept in the book.

The author of the best-selling "Java in a Nutshell" has created an entire book of real-world Java programming examples that you can learn from. If you learn best "by example," this is the book for you.

This third edition covers Java 1.4 and contains 193 complete, practical examples: over 21,900 lines of densely commented, professionally written Java code, covering 20 distinct client-side and server-side APIs. It includes new chapters on the Java Sound API and the New I/O API. The chapters on XML and servlets have been rewritten to cover the latest versions of the specifications and to demonstrate best practices for Java 1.4. New and updated examples throughout the book demonstrate many other new Java features and APIs.

"Java Examples in a Nutshell" is a companion volume to "Java in a Nutshell," "Java Foundation Classes in a Nutshell," and "Java Enterprise in a Nutshell," It picks up where those quick references leave off, providing a wealth of examples for both novices and experts. This book doesn't hold your hand; it simply delivers well-commented working examples with succinct explanations to help you learn and explore Java and its APIs.

"Java Examples in a Nutshell" contains examples that demonstrate:

Core APIs, including I/O, New I/O, threads, networking, security, serialization, and reflection

Desktop APIs, highlighting Swing GUIs, Java 2D graphics, preferences, printing, drag-and-drop, JavaBeans, applets, and sound

Enterprise APIs, including JDBC (database access), JAXP (XML parsing and transformation), Servlets 2.4, JSP 2.0 (JavaServer Pages), and RMI

The book begins with introductory examples demonstrating structured and object-oriented programmingtechniques for new Java programmers. A special index at the end of the book makes it easy to look up examples that use a particular Java class or accomplish a desired task. In between, each chapter includes exercises that challenge readers and suggest further avenues for exploration.

With literally hundreds of examples and thousands of lines of code, the "Java Servlet and JSP Cookbook" yields tips and techniques that any Java web developer who uses JavaServer Pages or servlets will use every day, along with full-fledged solutions to significant web application development problems that developers can insert directly into their own applications.

"Java Servlet and JSP Cookbook" presents real-world problems, and provides concise, practical solutions to each. Finding even one tested code "recipe" that solves a gnarly problem in this comprehensive collection of solutions and best practices will save hours of frustration--easily justifying the cost of this invaluable book.

But "Java Servlet and JSP Cookbook" is more than just a wealth of cut-and-paste code. It also offers clear explanations of how and why the code works, warns of potential pitfalls, and directs you to sources of additional information, so you can learn to adapt the problem-solving techniques to similar situations.

These recipes include vital topics like the use of Ant to setup a build environment, extensive coverage of the WAR file format and web.xml deployment descriptor, file-uploading, error-handling, cookies, logging, dealing with non-HTML content, multimedia, request filtering, web services, I18N, web services, and a host of other topics that frustrate even the most seasoned developers.

For Java web developers of all levels who are eager to put into practice the theory presented in other API-focused books, the solutions presented in this practical book will prove invaluable over and over again. This is painless way for less experienced developers who prefer to learn by doing to expand their skills and productivity, while accomplishing practical solutions to the pressing problems they face every day. More experienced developers can use these recipes to solve time-consuming problems quickly, freeing up their time for the more creative aspects of their work.

This book is your comprehensive guide to understanding Blockchain and Blockchain consensus algorithms. It covers distributed systems, distributed consensus, and relevant system models. And you'll explore how classical and modern consensus algorithms work. The book also covers quantum consensus and explains the role that quantum computing plays in distributed systems. Consensus protocols allow participants in distributed systems to agree on a common value, despite faults. It's a fundamentally important construct in distributed systems. As a result of rigorous and ground-breaking research over the last four decades, many consensus mechanisms have been developed and are used in the industry today. However, with the advent of Blockchain technology, a renewed interest has arisen in this area, resulting in more research and innovation. The first Blockchain, Bitcoin, was invented in 2008 and introduced a novel consensus protocol called Nakamoto consensus, a solution to the Byzantine General's problem formulated almost 30 years ago. Since the introduction of Bitcoin, the interest in Blockchain and consensus protocols has risen exponentially. As a result, researchers from academia and industry have proposed many new consensus mechanisms. While fundamental goals and some techniques remain the same as established classical protocols, these modern protocols introduce innovative methods to achieve consensus in Blockchain. Some classical algorithms have been modified to make them suitable for Blockchain and some new protocols have been developed. This book is a detailed account of classical distributed consensus and Blockchain consensus algorithms. It explains why and how cryptocurrencies and Blockchain remain secure and decentralized without depending on a trusted third party. In addition, you'll learn how Blockchain can endure, even with hundreds or thousands of participants, out of which some might be malicious. The book introduces quantum consensus, which deals with the problem of reaching agreement in quantum networks and how to enhance classical results. What You Will Learn Understand distributed systems, distributed consensus, and relevant system models and protocols Understand Blockchain and Blockchain consensus algorithms Know how classical and modern consensus algorithms work Know the inner workings of Paxos, RAFT, PBFT, HotStuff, proof of work, proof of stake, GRANDPA, Casper, proof of history, and other consensus protocols Understand quantum Byzantine agreement and quantum consensus Who This Book Is For Distributed systems and Blockchain students and researchers, Blockchain practitioners, architects, designers, product managers, and developers This book targets many audiences as well as those with curious minds. It explains the classical consensus mechanisms, Blockchain age consensus protocols, and the latest developments in distributed consensus. The book does not assume any advanced knowledge of Blockchain or distributed systems, but a general understanding of computing and appreciation of Blockchain technology is helpful. Early chapters provide the necessary background to read and understanding consensus-related content quickly. Readers who already understand classical consensus protocols and distributed systems but want to learn about Blockchain consensus will find the book helpful as it covers Blockchain age protocols in detail. Readers who have come to the Blockchain world without any, or with little, background in distributed systems or classical consensus protocols will find this book equally helpful as it provides a solid understanding of classical consensus protocols. If you have no experience in Blockchain or don't understand distributed computing in general, this book will give you a solid understanding of both subjects and enable you to conduct further research in this exciting area of distributed computing.

Crawford and Kaplan's J2EE Design Patterns approaches the subject in a unique, highly practical and pragmatic way. Rather than simply present another catalog of design patterns, the authors broaden the scope by discussing ways to choose design patterns when building an enterprise application from scratch, looking closely at the real world tradeoffs that Java developers must weigh when architecting their applications. Then they go on to show how to apply the patterns when writing realworld software. They also extend design patterns into areas not covered in other books, presenting original patterns for data modeling, transaction / process modeling, and interoperability.

The first edition of this book has been praised as "the best reference book available on the subject." This new edition, Programming ColdFusion MX, 2nd Edition, goes even further, documenting new techniques for using ColdFusion MX 6.1 to develop and serve dynamic web page content.
