Pattern-based solutions for every stage of the development lifecycle Documents 30 patterns, including the 23 core patterns for the Sun Certified Enterprise Architect exam.
Increasingly, developers are recognizing the value of design patterns in helping to create more robust, scalable, reliable, and maintainable applications. Now there’s a book that can help you bring the power of patterns to your Java-based projects.
Sun Microsystems experts Steve Stelting and Olav Maassen bring together today’s best pattern-based techniques and demonstrate pattern use for a variety of business systems. This practical guide features proven techniques for all types of patterns, from system architecture to single classes.
After briefly reviewing the fundamentals of design patterns, the authors describe how these patterns can be applied effectively to the Java platform. Next, they provide a pattern catalog, organized into four major categories—the creational, behavioral, structural, and system patterns. In addition, they identify patterns and present techniques for pattern use in the core Java APIs as well as the APIs for distributed development.
Applied Java Patterns also features a section on pattern use in systems built with J2EE and JINI technologies, and coverage of the servlet, JSP, EJB, and JavaSpaces APIs.
