About this paper

A Test for CSC 308 Java Programming at the University of Buea, dated 20th April 2022 (source is a graded handwritten student answer script; the student's identifying details and handwritten answers are excluded, with the solution derived independently from the printed questions). Question 1 is a 7-question MCQ set on bytecode, literals, platform-independence, object declaration, and three code-trace questions covering octal literals, pass-by-value versus pass-by-reference for arrays, and loop/variable scoping. Question 2 covers Java's one-public-class-per-file rule and tracing default field values versus assigned values. Question 3 is a fill-in-the-code exercise implementing a BankAccount class constructor and an overdraft check, with a full program output trace.
