Java API Design Guidelines Dr. Dichotomy's Development DiaryJava API Design Guidelinesby Eamonn McManusDecember 28, 2005 Summary There are tons of books and articles about how to design and write good Java code, but surprisingly little about the specific topic of API design. Here's a summary of what I've learnt on the subject from various sources and my own experience. I recently attended an excellent talk at JavaPolis, Elliotte Rusty Harold's XOM Design Principles. Although the talk is nominally about XOM (an API for XML documentation manipulation), in fact more than half of it is about API design principles in general. I've been closely involved with the evolution of the JMX API for over five years and have learnt a great deal about what works and what doesn't during that time. I'm going to try to summarize here what I see as being the key points from this talk, from my own experience, and from a couple of other sources: An excellent tutorial on netbeans.org, How to Design a (module) API.

JDepend JDepend Summary JDepend traverses Java class file directories and generates design quality metrics for each Java package. JDepend allows you to automatically measure the quality of a design in terms of its extensibility, reusability, and maintainability to manage package dependencies effectively. JDepend traverses Java class file directories and generates design quality metrics for each Java package, including: Number of Classes and Interfaces The number of concrete and abstract classes (and interfaces) in the package is an indicator of the extensibility of the package. Before using JDepend, it is important to understand that "good" design quality metrics are not necessarily indicative of good designs. The design quality metrics produced by JDepend are intended to be used by designers to measure the designs they create, understand those designs, and automatically check that the designs exhibit expected qualities while undergoing continuous refactoring.

Design pattern (computer science) There are many types of design patterns, for instance Algorithm strategy patterns addressing concerns related to high-level strategies describing how to exploit application characteristics on a computing platform.Computational design patterns addressing concerns related to key computation identification.Execution patterns that address concerns related to supporting application execution, including strategies in executing streams of tasks and building blocks to support task synchronization.Implementation strategy patterns addressing concerns related to implementing source code to support program organization, andthe common data structures specific to parallel programming.Structural design patterns addressing concerns related to high-level structures of applications being developed. History[edit] Although design patterns have been applied practically for a long time, formalization of the concept of design patterns languished for several years.[5] Practice[edit] Structure[edit] Criticism[edit]
Java Software Development Tutorials and Videos: Java, J2EE, Spring, Groovy, JavaFX, Eclipse, NetBeans, Hibernate Architecture Patterns Introduction | US Treasury Architecture Development Guidance (TADG) | IBM Patterns for e-Business | Some Pattern Resources This chapter provides guidelines for using architecture patterns. Introduction Patterns for system architecting are very much in their infancy. They have not (as yet) been integrated into TOGAF. Background A "pattern" has been defined as: "an idea that has been useful in one practical context and will probably be useful in others" [Analysis Patterns - Reusable Object Models]. In TOGAF, patterns are considered to be a way of putting building blocks into context; for example, to describe a re-usable solution to a problem. Patterns offer the promise of helping the architect to identify combinations of Architecture and/or Solution Building Blocks (ABBs/SBBs) that have been proven to deliver effective solutions in the past, and may provide the basis for effective solutions in the future.

JAVA DESIGN PATTERNS Prashant Satarkar He has a good experience into Java and J2EE designing and development. He has worked for many national and international clients as developer and designer on J2EE technologies. Requirement Analysis and Designing has been his core competency. He has also studied Rational Unified Processes. The design patterns can come in handy designing phase of the project. Here is a write-up by Mr. Abstract: “Pattern” as the name suggests, means series of events occurring in a definite order. Learning the design patterns is a multiple step process: 1. Patterns Defined: The patterns can be defined in many ways. “Design patterns are recurring solutions to design problems.” Patterns: According to commonly known practices, there are 23 design patterns in Java.
Code Generation Network Building Standards Compliant Web Sites Interaction Design Patterns -- maintained by Tom Erickson This page contains information about resources related to pattern languages for interaction design (of which user interface design is a subset), and a few links to more general papers that may be of use to interaction designers. I also include some links to organizational design patterns, which I find hard to disentangle from interaction design. Those interested should also see Jan Borcher's HCI patterns page. Those interested in other uses of pattern languages should see the Patterns Home Page , which is the most comprehensive source of information, and also Brad Appleton's Software Patterns Links .

Welie.com - Patterns in Interaction Design Software As She’s Developed » Blog Archive » AJAX Patterns: Design Patterns for AJAX Usability I’ve been putting together some AJAX design patterns. Update (May 15, 2005): I’ve set up AJAXPatterns.org to keep working on these patterns. I’ve also cleaned up a couple of things here, although all future changes will occur at ajaxpatterns. Thanks to Leoglas for spotting two errors here. Why AJAX Design Patterns? AJAX holds a lot of promise for web usability, and the underlying technology has already delivered some stunning applications. Patterns being patterns, there’s not a lot of unseen information here. This is a work-in-progress. Related Work Thomas Baekdal’s AJAX Usability Guidelines contains some great advice and inspired me to write these patterns. Design Principles for AJAX Applications Some (and eventually all?) Architectural Patterns Local Event-Handling You want the user experience to be dynamic and responsive, but it slows things down if you have to keep going to the server. Example: Websites have kept local information at hand for many years. Display Patterns Popup data input
