Java developers know that design patterns offer powerful productivity benefits but few books have been specific enough to address their programming challenges. With "Java Design Patterns", there's finally a hands-on guide focused specifically on real-world Java development. The book covers three main categories of design patterns--creational, structural, and behavioral--and the example programs and useful variations can be found on the accompanying CD-ROM.

Design patterns have become a staple of object-oriented design and programming by providing elegant, easy-to-reuse, and maintainable solutions to commonly encountered programming challenges. However, many busy Java programmers have yet to learn about design patterns and incorporate this powerful technology into their work.

Java™ Design Patterns is exactly the tutorial resource you need. Accessible and clearly written, it helps you understand the nature and purpose of design patterns. It also serves as a practical guide to using design patterns to create sophisticated, robust Java programs.

This book presents the 23 patterns cataloged in the flagship book Design Patterns by Gamma, Helm, Johnson, and Vlissides. In Java™ Design Patterns, each of these patterns is illustrated by at least one complete visual Java program. This practical approach makes design pattern concepts more concrete and easier to grasp, brings Java programmers up to speed quickly, and enables you to take practical advantage of the power of design patterns.

Key features include:

• Introductory overviews of design patterns, the Java Foundation Classes (JFC), and the Unified Modeling Language (UML)
• Screen shots of each of the programs
• UML diagrams illustrating interactions between the classes, along with the original JVISION diagram files
• An explanation of the Java Foundation Classes that illustrates numerous design patterns
• Case studies demonstrating the usefulness of design patterns in solving Java programming problems

After reading this tutorial, you will be comfortable with the basics of design patterns and will be able to start using them effectively in your day-to-day Java programming work.
