Overview
We know that most of the time invested in a software project is into its maintenance. As one of the world's leading companies in software craftsmanship, we have been applying Clean Code principles in our projects to minimize the cost & efforts on maintenance. In this session, we will share some of the basics and our experience of Clean Code in a Java example small enough to understand but big enough to relate to real-world projects.

Demo
We will look at the Expense Report example in Java 8, understand why its design smells, demonstrate the problems with legacy code, clean it up to make it maintainable and support some specific new requirements to be implemented.
In case you already know the Expense Report example from cleancoders.com, there's a surprise for you - The solution presented here will be different from the solution by Robert C. Martin…
Be prepared to a fast paced ride through the world of Clean Code!
