Class Description

Class Overview

Class Goals

• Start to think in terms of design patterns.
• Recognize and apply patterns to specific software development problems.
• Use known patterns as a shared vocabulary in designing and discussing solutions.
• Use Factories and Singletons to control object creation, for a variety of reasons.
• Use Observers, Observables, and Model/View/Controller systems to decouple application behavior and preserve code scalability.
• Understand the full motivation for the Command pattern and take advantage of Command frameworks in JFC.
• Implement Adapters, rather than building redundant classes or creating intermediate data structures for consumption by existing code.
• Understand and apply a range of other J2SE and J2EE patterns to improve code quality and scalability, and to produce high-quality solutions right off the bat.

Class Materials

All students receive a course manual or book and all the class examples.

Students in private onsite classes will also receive:

• Technical Reference Library

Class Prerequisites

Experience in the following areas is required:

• Solid Java programming experience is essential - especially object-oriented use of the language. Language features and techniques that are integral to some lab exercises include interfaces and abstract classes, threading, generics and collections, and recursive methods.
• Previous experience with UML (Unified Modeling Language) will be helpful, but is not critical. The course uses UML class diagrams extensively but keeps notation fairly simple, and also includes a quick-reference appendix.
