19 Aug 2003 Instead of writing new applications from scratch, much of a developer's job today involves changing existing code. Simple changes may consist of just adding on to the existing code. However, as multiple revisions or extensive changes are made, the internal structure of the software may begin to deteriorate. It can become difficult to understand, and expensive to modify and maintain. That is why it is important to know how to refactor code. Refactoring is changing the internal structure of software to make that software easier to understand and cheaper to modify without changing its observable behavior. In this tutorial, you'll learn about features in WebSphere Studio Application Developer that make refactoring easy.
Prerequisites
This tutorial assumes that you have experience developing applications with the Java platform. Knowledge of WebSphere Studio Application Developer is helpful but not necessary. If you are unfamiliar with JUnit, you may benefit from completing an earlier WebSphere Developer Domain tutorial, "Keeping critters out of your code".
System requirements
You do not need any special tools to read the tutorial. To follow along and perform the steps as demonstrated, you will need the a copy of WebSphere Studio Application Developer Version 5.
