Refactoring Lab

CSC 4700  Software Engineering

This is a hands-on lab activity that will broaden your understanding of refactoring and the use of Eclipse. This is for skills development and personal enrichment... there is nothing to hand in.

1. Start Eclipse and create a new Java project called "Utility"

2. In the Utility project, create a new Package called "calc"

3. In the calc package, create a new file called Utility.java

4. Copy and paste the code from Utility.java into the new file you created

5. Run the code, and figure out what it does

6. Refactor the code using Eclipse's automated tools (or manually when needed) to improve it as much as possible, by doing things like:

   • Rename the project, package, class, methods and variables as needed to be more meaningful

   • Remove unused variables

   • Reformate the source (Source->Format), experiment with Formatter in the Project->Properties->Java Code Style

   • Try to extract code (sometimes repeated code) into a method

   • Try to change a method signature

   • Explore online resources for using Eclipse to refactor Java code

   • Show your instructor what you have accomplished

   • Share with others the techniques you have discovered
