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
Enter Option B (Start with * for correct answer) >> primitive
Enter Option C (Start with * for correct answer) >> *type-wrapper
Enter Option D (Start with * for correct answer) >> show
How many points? 3
Please choose (c)reate a question, (p)review or (e)xit >> c

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.
