Generics and the greatly expanded collection libraries have tremendously increased the power of Java 5 and Java 6. But they have also confused many developers who haven't known how to take advantage of these new features. Java Generics and Collections covers everything from the most basic uses of generics to the strangest corner cases. It teaches you everything you need to know about the collections libraries, so you'll always know which collection is appropriate for any given task, and how to use it. Topics covered include: Fundamentals of generics: type parameters and generic methods Other new features: boxing and unboxing, foreach loops, varargs Subtyping and wildcards Evolution not revolution: generic libraries with legacy clients and generic clients with legacy libraries Generics and reflection Design patterns for generics Sets, Queues, Lists, Maps, and their implementations Concurrent programming and thread safety with collections Performance implications of different collections Generics and the new collection libraries they inspired take Java to a new level. If you want to take your software development practice to a new level, this book is essential reading. Philip Wadler is Professor of Theoretical Computer Science at the University of Edinburgh, where his research focuses on the design of programming languages. He is a co-designer of GJ, work that became the basis for generics in Sun’s Java 5.0. Maurice Naftalin is Technical Director at Morningside Light Ltd., a software consultancy in the United Kingdom. He has most recently served as an architect and mentor at NSB Retail Systems plc, and as the leader of the client development team of a major UK government social service system.

Written for programmers and developers, this text provides the necessary information for Java programmers to find, evaluate, and select suitable application frameworks. It also explains the benefits of frameworks and component technologies.

With Java 5.0, you'll not only find substantial changes in the platform, but to the language itself-something that developers of Java took five years to complete. The main goal of Java 5.0 is to make it easier for you to develop safe, powerful code, but none of these improvements makes Java any easier to learn, even if you've programmed with Java for years. And that means our bestselling hands-on tutorial takes on even greater significance. Learning Java is the most widely sought introduction to the programming language that’s changed the way we think about computing. Our updated third edition takes an objective, no-nonsense approach to the new features in Java 5.0, some of which are drastically different from the way things were done in any previous versions. The most essential change is the addition of “generics”, a feature that allows developers to write, test, and deploy code once, and then reuse the code again and again for different data types. The beauty of generics is that more problems will be caught during development, and Learning Java will show you exactly how it’s done. Java 5.0 also adds more than 1,000 new classes to the Java library. That means 1,000 new things you can do without having to program it in yourself. That’s a huge change. With our book’s practical examples, you'll come up to speed quickly on this and other new features such as loops and threads. The new edition also includes an introduction to Eclipse, the open source IDE that is growing in popularity.

That’s the idea in JavaServer Pages, a very approachable and patient tutorial suitable for anyone with basic HTML knowledge. Early sections explain how JSPs and Java servlets work. (In short, JSPs provide an easy way to write servlets, a powerful alternative to CGI scripts or Microsoft Active Server Pages, ASPs). With JSPs, you write HTML with embedded tags, so you don't have to be a Java expert to use them. The strength of this text has to be the author’s practically minded tutorial showing these pages in action. Dozens of short programming excerpts provide a solid tour of basic techniques, including retrieving form variables and generating dynamic content for a sample news Web site. Later, the author delves into the Java programming language itself, along with custom JavaBeans for use within JSPs. Closing chapters enhance the sample Web site with personalization and even basic e-commerce capabilities. Chances are this case study is all you need to start making use of JSPs and beans successfully on your own. By centering on JSPs first and then working inward to the details of Java, the text can benefit a wide range of readers. Content creators can learn JSPs and gain exposure to some real Java, while serious Java programmers can learn a much simpler approach to writing servlets. Provided you know HTML and the basics of Web development, this easy-to-digest and worthwhile book can let you build Web sites that take advantage of one of today’s most powerful server-side technologies. Topics covered: History of dynamic content with HTML, CGI scripts, Active Server Pages (ASPs), introduction to Java Server Pages (JSPs) and servlets, JSP comments and basic statements, error handling, request time processing and expressions, implicit JSP objects, retrieving user form variables, properties and serialization, basic Java programming (variables, keywords, objects, and simple class design), JSP scriptlets, conditionals, scoping rules, local, page, request and session scope, managing session information, designing JavaBeans, database and SQL basics, personalization techniques, dynamics ads, adding simple e-commerce capabilities, servlet events and APIs, using servlets with JSPs, introduction to XML and multithreaded programming, sample JSP code, and a case study for a news Web site. — This text refers to an out of print or unavailable edition of this title.

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

"I've been paged at 3:00 a.m. to provide support because the system wasn't doing what it should and no one had a clue how to figure out why. I've scrolled through endless log files to decipher system problems, when a management solution could have presented an operator with a warning message hours earlier!" Wanting other developers to be able to learn from his experiences, Steve wrote Java Management Extensions. Java Management Extensions is a practical, hands-on guide to using the JMX APIs, Sun Microsystems’s new Java-based tool for managing enterprise applications. This one-of-a-kind book is a complete treatment of the JMX architecture (both the instrumentation level and the agent level), and it’s loaded with real-world examples for implementing management extensions. It also contains useful higher-level information about JMX (the "big picture") to help technical managers and architects who are evaluating various application management approaches and are considering using JMX. This book takes developers through JMX step by step, pointing out the “gotchas” before they have a chance to trip up smooth operation of the application. As J2EE becomes more widely adopted, the Java standard for management (JMX) becomes more and more crucial to avoid "splinter standards," where each vendor has its own distinct, if successful, way of doing things.

Java is fashionable, but is it reliable? Java is entertaining, but is it secure? Java is useful, but is it safe? The purpose of this book is to answer those questions, from the point of view of people who want to use Java, but want to do so reliably, securely and safely.Показать полностьюJava is fashionable, but is it reliable? Java is entertaining, but is it secure? Java is useful, but is it safe? The purpose of this book is to answer those questions, from the point of view of people who want to use Java, but want to do so reliably, securely and safely. That makes this book different from much recent writing on Java, which focuses, perfectly legitimately, on how a Java system can be broken into and how to avoid those dangers. On the contrary, this book focuses on how Java can be made secure and how to exploit its strengths. The goal is to provide practical help to the various groups involved in making a Java-based application or Web site into an industrial-strength commercial proposition. Various groups have different needs and different skills, which this book meets in its different parts. * The first part is aimed at the intelligent non-specialist who oversees system management or application development, or incorporates Java into the security policy. Only a basic understanding of computers and a limited exposure to Java is assumed, but all the themes of Java security are introduced in a context that stresses over and over again how Java security must be seen as an integral part of system security. * The second part goes into more detail on how Java security works, and is aimed more at system and network administrators and programmers, who need to know more of what is going on. * The third part looks at the broader context in which Java operates, including some extensions to Java security and some aspects of its future. This book explains the evolution of the Java security model, andthenfocuses on the Java 2 security architecture and its revolutionary domains of protection. It offers a very large number of examples to give you a better understanding of the technology involved.

If you're a Java programmer working in an Oracle environment, you're probably familiar with JDBC as a means of accessing data within an Oracle database.Показать полностьюIf you're a Java programmer working in an Oracle environment, you're probably familiar with JDBC as a means of accessing data within an Oracle database. SQLJ takes you further, allowing you to access a database using embedded SQL statements. Java Programming with Oracle SQLJ shows you how to get the most out of SQLJ. Layered on top of JDBC, SQLJ greatly simplifies database programming. Rather than make several calls to the JDBC API just to execute a simple SQL statement, SQLJ executes that statement simply by embedding it within the Java code. In this book, Jason Price explains SQLJ programming from a task-oriented point of view. You'll learn how to: * Embed queries and other SQL statements within Java programs * Deploy SQLJ code not only on client machines, but also to JServer — Oracle’s Java engine built into the database * Use advanced techniques for working with collections, streams, large objects, and database objects, all without leaving the comfort of the SQLJ environment * Tune SQLJ programs for maximum performance Throughout the book, the exposition of SQLJ and SQLJ programming techniques reflects the author’s many years of professional experience as a programmer and consultant. Examples are first-rate, enabling you to learn SQLJ in no time. If you're writing Java code to access an Oracle database, you can't afford not to know about SQLJ.
