JV240: Java and Java EE Design Patterns (2-3 days*)
Course Overview
Design patterns are recurring solutions to common software problems.
The specific details of a software problem may vary from project to project
but patterns capture the essence and basic structure of successful
experiences in solving similar problems. Design patterns thus offer a
technique for capturing design and architecture, presenting and
communicating architectural knowledge at all levels of a system,
allowing experience and insights to be understood and distilled.
This course is an in-depth introduction to design patterns for Java and
J2EE systems and is designed for intermediate Java programmers wanting to
advanced their mastery of the Java language by adopting best-practice
coding conventions and patterns.
View sample slides: PatternsOverview
Covered patterns include fundamental patterns, creational patterns, behavioural patterns, structural patterns, system patterns, concurrency patterns, inter-tier data transfer patterns, presentation-tier patterns, business-tier patterns, persistence-framework patterns and integration-tier patterns.
Business Benefits
Design patterns incorporate proven techniques which embody the wisdom and experience of master practitioners and provide the following business benefits:
- Patterns can save programmers costly time by offering time-tested patterns rather than requiring developers to invent, test and debug their own designs from scratch.
- Patterns can reduce maintenance costs because most are created to assist refactoring and support evolvability.
- Finally, design patterns can increase team productivity because the team can communicate about their design options and choices using well-undertood, high-level pattern terminology rather than explaining low-level coding details.
Audience
Software Developers, Designers, Technical Managers and Architects interested in a hands-on exploration of Java & J2EE Design Patterns.
Pre-requisites
Students should be experienced programmers with a strong Java background. A basic knowledge of distributed computing, (RMI and/or CORBA/Java, J2EE), and a working knowledge of Servlets, JSPs and EJBs.
