Exercise 1 Create a class called Question that simulates short-answer style questions to be placed on a quiz. Each Question object should have a question, an answer, and a difficulty level.

The difficulty level should be an integer between 1 and 10 that represents the difficulty level of the question (1 being easy, 10 being hard).

Overload the constructor so that it only accepts 2 parameters, the question and answer, and sets the difficulty to a default value of 1.

Make sure to use the this keyword. Create the getters and setters for the instance data of this class.

Create a toString method that returns a string summary of the Question object.

Create a method boolean isCorrect(String attemptedAnswer) that returns true if the attempted answer is the correct answer for the current question.

Exercise 2 Download and run the TestQuestion and ensure that your Question class passes all of the JUnit tests. Do not modify the unit test file.

Exercise 3 Create a class called Quiz that uses your Question class to create Quiz objects. A Quiz can be composed of up to 25 questions and a score. The Quiz constructor should initialize an ArrayList and the score accordingly. Create a way to keep track of the total number of quizzes ever created. Create a method called void add(Question q) that adds a new question to the quiz. What should happen if we try to add a 26th question to a quiz? Create only the necessary getters and setters. Create a method called void giveQuiz() that presents each question, and its difficulty, in turn to the user, accepts an answer for each one, and keeps track of the results.

Exercise 4 Create a tester class (read: not a JUnit test class) called QuizTime that creates and populates a Quiz, presents it, and prints the final results. Pick an interesting topic to make your quiz about. To the right is a Sample Output for one execution of QuizTime.

Exercise 5 Currently the difficulty of the questions is not used in creating the quizzes. Overload the giveQuiz method in the Quiz class so that it accepts two integer parameters that specify the minimum and maximum difficulty levels for the quiz questions and presents only questions in that difficulty range. Hint: work smarter not harder, dont duplicate code. If your overridden method contains almost all of the same lines of code as the original giveQuiz method, youre doing it wrong. Create another Quiz in your tester class that demonstrates this new feature. Also demonstrate that you successfully track the total number of quizzes created. To the right is a Sample Output for one execution of QuizTime
