Object-Oriented Refactoring Course Description

Refactoring is the process of changing a software system in such a way that it does not alter the external behavior of the code yet improves its internal structure. It is a disciplined way to clean up code that minimizes the chances of introducing bugs.

Use of object-oriented programming is to create software that is easy to modify and extend. In order to achieve this, we first have to look at why code tends to rot. We have to be able to recognize the code smells that indicate that code rot is occurring. Once we’ve detected the code rot, we have to apply object-oriented principles to refactor the code and eliminate the problem.

The Object-Oriented Refactoring training course teaches students the motivations, pitfalls, and the art of refactoring object-oriented solutions. The course also teaches students how to perform safe refactoring using Integrated Development Environments like Eclipse, NetBeans and IntelliJ, and a test-first, test-driven process.
