Object-Oriented Design

Object-oriented design (OOD) is a vital skill for today's programmers. Those who possess a solid understanding of OOD often find ways to simplify designs, even for complex problems. Whether you are new to objects or have worked with an object-oriented language for years, this activity will demystify OOD and help you learn to fully utilize your language's object-oriented features.

Flavor: fundamentals
60 to 90 minutes
This activity offers an interactive introduction/review of polymorphism, inheritance vs. delegation, interfaces and dependency management.
