This is the first of three volumes of the Harnessing JavaTM 7 book. It provides a comprehensive approach to learning the Java programming language to all levels of Java developers. It covers the fundamental topics of Java in detail such as Object-Oriented concepts, data types, operators, etc.It contains more than 70 diagrams to help programmers visualize and understand the topics better.More than 170 complete programs included in this volume help beginners and intermediate level programmers learn the topics faster.The second chapter, "Writing Java Programs", has been especially designed for beginners,which walks you through writing your first Java program step-by-step. The following topics are covered in this volume. Programming Concepts Data Types Operators Statements Classes and Objects Object and Objects Classes AutoBoxing Exception Handling Assertions Strings & Dates Formatting Objects Regular Expressions Arrays Garbage Collection Inheritance It covers the following new features of JavaTM 7 in detail. Binary Numeric Literals Underscores in Numeric Literals Strings in a switch Statement try-with-resources Statement Catching Multiple Exception Types Re-throwing Exceptions with Improved Type Checking The java.util.Objects class

Fra bagsiden: As a platform, Java defines the services needed to connect binary components at runtime safely and reliably. To truly take advantage of alle Java has to offer, you must consider not just development, but also deployment, and not just objects, but also components. The book delves into the component-oriented features of the Java platform, thoroughly discussing class loading, refelction, serialization, native interoperation and code generation.

Learn core programming concepts and technologies on the leading software development language This full-color book covers fundamental Java programming concepts and skills for those new to software development and programming. Taking a straightforward and direct approach,Java SE 7 Programming Essentials provides a solid foundational knowledge of programming topics. Each chapter begins with a list of topic areas, and author Michael Ernest provides clear and concise discussion of these core areas. The chapters contain review questions and suggested labs, so the reader can measure their understanding of the chapter topics. Covers topics such as working with Java data types, using operators and decision constructs, creating and using arrays, and much more Includes additional learning tutorials and tools Puts the focus on Oracle's new Oracle Certified Associate (OCA): Java SE 7 Programmer (1Z0-803) exam This must-have resource offers new programmers a solid understanding of the Java SE 7 programming language.

Are you looking for a deeper understanding of the JavaTM programming language so that you can write code that is clearer, more correct, more robust, and more reusable? Look no further! Effective JavaTM, Second Edition, brings together seventy-eight indispensable programmer’s rules of thumb: working, best-practice solutions for the programming challenges you encounter every day. This highly anticipated new edition of the classic, Jolt Award-winning work has been thoroughly updated to cover Java SE 5 and Java SE 6 features introduced since the first edition. Bloch explores new design patterns and language idioms, showing you how to make the most of features ranging from generics to enums, annotations to autoboxing. Each chapter in the book consists of several “items” presented in the form of a short, standalone essay that provides specific advice, insight into Java platform subtleties, and outstanding code examples. The comprehensive descriptions and explanations for each item illuminate what to do, what not to do, and why. Highlights include: New coverage of generics, enums, annotations, autoboxing, the for-each loop, varargs, concurrency utilities, and much more Updated techniques and best practices on classic topics, including objects, classes, libraries, methods, and serialization How to avoid the traps and pitfalls of commonly misunderstood subtleties of the language Focus on the language and its most fundamental libraries: java.lang, java.util, and, to a lesser extent, java.util.concurrent and java.io Simply put, Effective JavaTM, Second Edition, presents the most practical, authoritative guidelines available for writing efficient, well-designed programs.

Bruce Tate, author of the Jolt Award-winning Better, Faster, Lighter Java has an intriguing notion about the future of Java, and it's causing some agitation among Java developers. Bruce believes Java is abandoning its base, and conditions are ripe for an alternative to emerge. In Beyond Java, Bruce chronicles the rise of the most successful language of all time, and then lays out, in painstaking detail, the compromises the founders had to make to establish success. Then, he describes the characteristics of likely successors to Java. He builds to a rapid and heady climax, presenting alternative languages and frameworks with productivity and innovation unmatched in Java. He closes with an evaluation of the most popular and important programming languages, and their future role in a world beyond Java. If you are agree with the book's premise--that Java's reign is coming to an end--then this book will help you start to build your skills accordingly. You can download some of the frameworks discussed and learn a few new languages. This book will teach you what a new language needs to succeed, so when things do change, you'll be more prepared. And even if you think Java is here to stay, you can use the best techniques from frameworks introduced in this book to improve what you're doing in Java today.

Here users can get fast access and accurate reference to the Java language commands needed for creating sophisticated, Java-enhanced web pages. Designed for all levels of Java programmers who need to reference a command they've forgotten or want to double-check, this is the at-your-fingertips guide to the complex Java language.

Review over 150 real-world Java interview questions you are likely to encounter Prepare for personality-based interviews as well as highly technical interviews Explore related topics, such as middleware frameworks and server technologies Make use of chapters individually for topic-specific help Use the appendix for tips on Scala and Groovy, two other languages that run on JVMs Veterans of the IT employment space know that interviewing for a Java programming position isn't as simple as sitting down and answering questions. The technical coding portion of the interview can be akin to a difficult puzzle or an interrogation. With Java Programming Interviews Exposed, skilled Java coders can prepare themselves for this daunting process and better arm themselves with the knowledge and interviewing skills necessary to succeed.

Drawing on the authors knowledge of the Java programming language and their extensive experience working on performance issues, the book reveals common mistakes and misconceptions concerning the performance characteristics of Java technologies. It offers overall development strategies and concrete, battle-tested techniques to dramatically improve the performance of applications constructed with the Java programming language. Java Platform Performance highlights the importance of integrating performance evaluation into the application development process and discusses measurement techniques. The book then presents practical tactics for enhancing application performance in the areas of I/O, RAM footprint, small object management, algorithms, data structures, Swing, and deployment. Specific topics covered include: *Incorporating performance evaluation into the development process *Profiling and benchmarking *Building scalable, fast Swing GUIs *Using high-speed I/O *Computing and controlling the RAM footprint *Reducing the number of classes *Eliminating temporary objects *Selecting high-performance algorithms and data structures *Using Java native code and applet packaging efficiently
