✦ Synopsis

Design Patterns in Java(TM)gives you the hands-on practice and deep insight you need to fully leverage the significant power of design patterns in any Java software project. The perfect complement to the classicDesign Patterns, this learn-by-doing workbook applies the latest Java features and best practices to all of the original 23 patterns identified in that groundbreaking text.

Drawing on their extensive experience as Java instructors and programmers, Steve Metsker and Bill Wake illuminate each pattern with real Java programs, clear UML diagrams, and compelling exercises. You'll move quickly from theory to application--learning how to improve new code and refactor existing code for simplicity, manageability, and performance.

Coverage includes


Using Adapter to provide consistent interfaces to clients
Using Facade to simplify the use of reusable toolkits
Understanding the role of Bridge in Java database connectivity
The Observer pattern, Model-View-Controller, and GUI behavior
Java Remote Method Invocation (RMI) and the Proxy pattern
Streamlining designs using the Chain of Responsibility pattern
Using patterns to go beyond Java's built-in constructor features
Implementing Undo capabilities with Memento
Using the State pattern to manage state more cleanly and simply
Optimizing existing codebases with extension patterns
Providing thread-safe iteration with the Iterator pattern
Using Visitor to define new operations without changing hierarchy classes If you're a Java programmer wanting to save time while writing better code, this book's techniques, tips, and clear explanations and examples will help you harness the power of patterns to improve every program you write, design, or maintain.
