Dependency Inversion – code cast
Blog post series
This blog post is part of a series about legacy coderetreat and legacy code techniques you can apply during your work. Please click to see more sessions about legacy code.
Code Cast
This is a code cast in Java.
During this code cast you will see how to use the concept of Dependency Inversion on a legacy code base. Dependency Inversion is one way of transforming a tightly coupled system into a system that has a core and many small external dependencies. These external dependencies can be called also plugins. Read more about this concept in my previous blog post.

I think you forgot to delete the ConsoleOutput from the default constructor, no?
Yes, you are right, I forgot to delete the instantiation from the Game default constructor. Anyway f you delete that line of code, the code works well. Please see the code here: https://github.com/adi-bolb/trivia/blob/code-cast-6-dependency-inversion/java/src/main/java/com/adaptionsoft/games/uglytrivia/Game.java
And thanks for the vigilance 😉
Thanks, nice series btw! 🙂
