Refactoring to Clean Code With samples in C# and Java

Course details

Clean code and refactoring have emerged as an essential guideline and technique for modern software development. Clean code, as the name implies, gives programmers a comprehensive set of guidelines on to how to write a code that is easy to understand, test, and maintain. Refactoring describes a catalogue of techniques and mechanisms that enable programmers to transform existing ugly codebases to a cleaner state. Both clean code and refactoring emerged in agile environment, and are considered the primary tools that allow agile teams to be more responsive to change while producing high quality products. Yet, both can be used outside an agile environment to enhance the quality and maintainability of software products.

This course is structured as an intense set of lectures and workshops that enable attendees to immediately apply the topics covered. Attendees will watch their mentors live as they transform ugly codebases into clean code using both; the refactoring techniques and the clean code guidelines. Attendees will then get their chance in applying what they have seen in similar situations.

This is a BYOD (Bring Your Own Device) course. Each attendee is expected to bring along a portable computer with a suitable Java or C# IDE installed and operational. The mentors will contact the attendees before the start of the course to ensure proper installation and operation of the environment.
