Java Rules (DevelopMentor) (Paperback)

Java™ Rules distills the Java Language Specification into an extraordinary resource for every Java developer. Doug Dunn has eliminated obscure information only needed by JVM and compiler developers, and added crucial real-world guidance not found in the spec. The result: the most readable, accessible Java reference ever created. Java™ Rules offers a thorough overview of the Java 2 Platform, the java.lang, java.io, and java.util packages, and associated APIs and class libraries. Long-time consultant and trainer Doug Dunn introduces the inner workings of the language with exceptional clarity, detailing fine points and delivering expert tips for creating robust, efficient software. Topics covered include: lexical structure, compilation units, application programs, packages, JAR files, versioning, reference types, variables and constants, strings and arrays, and much more. For all beginning-to-intermediate level Java programmers, including experienced developers in other languages who want a Java tutorial and reference that respects their expertise.

Detailed yet accessible, Java™ Rules is a comprehensive reference for the application programmer who needs to master the intricacies of the Java™ programming language. Thoroughly describing the core of the Java programming language and the Java™ virtual machine (JVM™), Java™ Rules makes it possible for programmers to efficiently master the Java platform.

Based on the second editions of The Java™ Language Specification and The Java™ Virtual Machine Specification, Java™ Rules presents a subset of those specifications in a gentle tutorial style. From platform basics to APIs, this encyclopedic guidebook reveals every facet of the language--including previously undocumented features. Throughout the book, practical tutorials are supported with official language documentation or with insights shared by respected leaders. The book's unique format and conversational style are ideally suited for experienced programmers seeking a short path to language proficiency.

As both a tutorial and detailed reference, this volume of Java™ Rules covers:

• Lexical structure, escape sequences, and positional notation systems
• The anatomy of a compilation unit
• The five kinds of classes and interfaces
• Containment and inner class hierarchies (versus inheritance hierarchies)
• The static modifier, this and super
• Primitive data types and Object
• Strings and other common data types
• Arrays and the Collections Framework

With Java™ Rules in hand, both novices and experienced programmers can quickly master the language.
