CEC 302 Introduction to Object Oriented programming Resit 2024

About this paper

CEC 302: Second Semester Resit Examination 2023/2024, 03/07/2024 (instructor Dr Denis Nkweteyim), University of Buea: a 21-mark True/False and code-trace question (exceptions, array-vs-primitive passing, pass-by-value, a super() fill-in); a 27-mark question building an abstract Shape/Rectangle/Square hierarchy for a 7-shape inheritance tree; and a 27-mark Date/Student/UGStudent/GStudent inheritance-chain coding question (this paper's own lettered parts omit asking for GStudent's code even though part (d) requires creating a GStudent object, so GStudent is additionally implemented here, following the UGStudent pattern, to make that line of code well-defined).
