Oral Assessment 7 will focus on the Liskov's treatment subtyping.
You should focus on the type of analysis required for exercise 13. That is, I will give you a method signature and two contracts, one for a supertype, and one for a subtype. As we work through variations on what's a precondition, what's a postcondition, and what the postcondition specifies, you should be able to state whether Liskov's two rules for analyzing methods are satisfied and, if not, why not.
Since I want all students to understand every week of the semester, it's possible that your oral assessment will address last week's topic. Be prepared for both!
This guide covers oral assessments administered between Monday, October 12 and Friday, October 16.
