Checkliste og spørgsmål MIP eksamen
For kurset i objekt-orienteret programmering er eksamen en 48 timers
programmeringsopgave. Dette er den generelle checkliste og spørgsmål som
censor og eksaminator bruger til at vurdere de afleverede MIP opgaver.
Checkliste og spørgsmål er på engelsk da de er diskuteret med ikke dansk
talende personer.
Checkliste og spørgsmål kan er IKKE en komplete liste af spørgsmål der kan stilles
til MIP eksamen, men kan bruges til at orientere sig om hvad det er vi lægger vægt på.
Spørgsmål
Dette afsnit lister en række spørgsmål, der skal bruges til
at afdække de studerendes faglige niveau og hvad de burde kunne
svare på i henhold til kursets indlæringsmål.

Checkliste
Dette er en checkliste af de ting vi kigger på for hver MIP opgave. Listen er IKKE komplet,
men skal vise, hvad det er vi kigger på.
- Do classes/methodes/variables/parameters have reasonable names?
- JavaDoc on all public constructions (and relevant private)?
- Implemented in the default package?
- Method overloading used?
- Are constructors used/overloaded?
- Method redefined in particular is toString, clone, equals redefined?
- Are access methods used (get/set methods)?
- Are instance variables private/protected?
- Is the iterator design pattern used instead of for loops?
- Is code repeated, i.e., has copy-paste been used anywhere in the program?
- Are the hardwired or "magic" values in the program?
- Is Serialization used?
- Is the String data type used for dates?
- Is UI code mixed with "core" code (if the UI is changed then also necessary to change core classes)?
- Return used at end of procedures or constructors?
- Polymorph call of methods?
- Is structured exception handling used?
- Are pre/post conditions used?
