Question

Description
In this assignment, you are required to implement an electronic programming quiz system. User can create
questions and preview the quiz.
Your Task
You are asked to write a Java program for the programming quiz system. There are two types of questions:
Multiple Choice Question and Ture/False Question. User can create questions using the system; and
preview the quiz, which display all questions in the system one by one. During the preview, the user can
attempt the quiz by entering his/her answers to questions. The system will then immediately check the
answer and calculate. After attempting all questions, the total score will be displayed. A sample run of the
program is shown as below (Green text refers to user input): 

Please choose (c)reate a question, (p)review or (e)xit >> c
Enter the type of question (MC or TF) >> MC
Enter the question text >> Each primitive type in Java has a corresponding
class contained in the java.lang package. These classes are called ____
classes.
How many options? 4
Enter Option A (Start with * for correct answer) >> case

Question Class:
- This class represents the generic form of question. It contains the question text (qText) and
the point of a question (point).
- The grade method, which is an abstract method, has a parameter, answer (String). It returns
the points of the question if the answer is correct; zero otherwise.
- The getCorrectAnswer method, which is an abstract method, has no parameter. It returns a
String representing the correct answer to the question.
MCQuestion Class
- It is a subclass of Question.
- It represents a multiple-choice question. A multiple-choice question may have 3-5 options.
- Each element of the instance variable options refers to an option in this question.
- The instance variable answer is a single-character string. It saves the correct answer (“A”,
“B”, “C”, “D” or “E”) to this question.

The method setoptions (String options) has the answer field from the database
(explained below) as the parameter. It will add all options to the instance variable options
and set the instance variable answer.
The constructor MCQuestion(String qText, String options, double point)
creates an MCQuestion object by setting the qText, adding option to options , setting the
correctAnswer to answer and point by reading the QText, Answer, and Point fields from
the database,
The grade method returns the points of the question if the parameter, which can be "A", "B",
"C", .., is equal to the instance variable answer, zero otherwise.
The getCorrectAnswer method returns the letter (i.e. "A", "B", "C", ...) representing the
correct answer.
TFQuestion Class
It is a subclass of Question.
It presents a True/False question.
The instance variable answer is a boolean variable representing the correct answer of the
question (i.e., True or False).
The constructor TFQuestion(String qText, boolean answer, double point)
creates an TFQuestion object by setting the qText, answer, and point by reading the
qText, Answer, and Point fields from the database.
The grade method returns the points of the question if the parameter, which can be "T" or
"F", is equal to the instance variable answer, zero otherwise.
The getCorrectAnswer method returns the letter "T" or "F" representing the correct answer.
3. You must read/write from/to the database provided in this question (Question.accdb). This MS
Access file contains a table called Questions. It contains the following fields:
a. ID (Automatically generated integer by MCAccess)
b. QText (Short Text): The question text
c. Answer (Short Text):
i. If this is a multiple-choice question, Answer stores all options separated by "#".
There is a leading *** for the correct option.
i1. If this is a True/False question, Answer stores the string "Ture" or "False".
d. Point (Single): It is a float point number representing the point of this question.
e. Type (Short Text): "MC" or "TF" denoting multiple-choice or True/False questions
respectively.
4. Question.accdb contains no record at the beginning.
5. You must create a class Asgn03, which has the main method to run the program.
6. Refer to the following screenshots for the data format saved in the database.
