The definitive style guide for writing readable, maintainable Java code With Essential Java Style, developers finally have a Java style guide that offers detailed patterns for real-world implementation. Using [GGD1]real code, not abstract discussion, Jeff Langr brings together scores of today's best implementation solutions for the problems every Java developer faces. By standardizing these solutions, developers can build Java programs more quickly, efficiently, and reliably-and above all, make them dramatically easier to maintain. Langr brings together the most useful ideas from many sources, notably the excellent Smalltalk patterns identified in Kent Beck's Smalltalk Best Practice Patterns (Prentice Hall, ISBN: 0-13-476904-X). The patterns in Essential Java Style cover methods, messages, state, collections, classes, and formatting. Each pattern appears on its own page, with its own name and summary box designed to show exactly which problem is being solved. Streamline the development processes by using these patterns to eliminate random coding and naming styles that complicate maintenance, overly procedural code that can be difficult to understand, and varying techniques for common operations that are often inefficient. Essential Java Style will be an invaluable reference for Java developers, managers, and other technical professionals throughout the entire project lifecycle by providing:

  • The industry's best solutions for dozens of common operations
  • Techniques for both JDK 2 and JDK 1.1
  • Detailed coverage of the Java 2 Collections Framework
  • Techniques for making code more understandable without extensive commenting
  • Detailed patterns for real-world implementation
  • Real "best-practices" code for real Java challenges
  • Patterns covered include behavior, state, collections, classes, and formatting
  • The ideal reference for team-based development!
