289636 Multiple choice java program

Mini-project 2: A multiple choice exam for Java programming

Write a program that provides a multiple-choice question exam for the Java programming language. The

number of questions should be substantial (>50) and should cover all aspects studied in the 1st year Java

courses (>30 should be on the topics covered in Object Oriented Programming).

Level 1

Includes screen output and keyboard input and basic classes.

There are Java source files for at least three major classes of the program.

Good source comments and code indentation is expected for all implemented parts of the program.

Example: The program reads the questions and answers and prints them.

Level 2 –

Includes methods and variables for at least three major classes, and all constructions above.

At least 3 major methods fully implemented and working for each class

Example: As above, but also questions are displayed on the screen, and answers are classified as correct or

wrong.

Level 3 –

At least three major program classes will be implemented, with methods working and well designed, and

all constructions above

Use of inheritance with at least one superclass and three subclasses

Class, method and variable naming will be clear and consistent

Example: As above, but also questions and answers are defined using inheritance, e.g. questions can be easy

(e.g. two alternatives), medium (e.g. 4 alternatives), difficult… or open (several alternatives + the option for

the user to enter another possible answer)

Level 4

Polymorphism should be used in at least three subclasses, and all constructions above

Exception handling is used to catch and handle at least three different types of exceptions

At least four major program classes will be implemented, with methods working and well designed,

Comments are clear and applied to class and method level consistently

Example: As above, plus the behaviour of the system with respect to the user input is handled using

polymorphism.

Level 5

Use of Vectors in all parts of the program, and all constructions above.

Exception handling is carried out appropriately in all parts of the program.

Inheritance is correctly applied to all parts of the program.

Example: As above, but questions and answers are now stored into vectors, and once the user has submitted

an answer this cannot be changed. A GUI will also be included: questions and answers are shown on a

window, answers provided by clicking buttons or using text areas for open questions.

Level 6

Includes file input and/or output, and all constructions above

The systems will be displayed on a fully working GUI (including opening and saving files).

Example: As above, plus at the end of the exam an analysis is provided (e.g. “answer x was wrong; correct

answer was y because z”). It should be possible to save the user session into a file, and read questions and

answers from a file.
