JAVA HELP! Can you add questions and covert chapter numbers into points and make an application that calls them over 100? Create a new NetBeans 8.2 Java 8 project called TestSimulator. Add the eight classes from the UML class diagram in a package called “testsimulator” as shown below. Create a class stub for each class such as below: public class ClassName { } Add the necessary additional keywords for classes that inherit from interfaces or abstract classes. Part 2: Main menu Consult the UML class diagram and add implementation to the TestSimulator class as follows: getSelection() method: • Print the following menu-based messages: Welcome to the TestSimulator program menu. Select from one of the following options. (1) New test. (2) Test summary. (3) Exit. Enter your selection: • Accept the choice from the user. • Ask the user to enter their choice again if a non-number is received. main() method: • Add a loop that runs the getSelection() method until the user enters option (3). • Add a branching construct that prints a message regarding the user’s choice for each option. • The program finishes normally after option (3) is selected. Part 3: Question class The Question class is an abstract class that represents one question for a test. It contains details about the question, but not much about the answers. This is because there are different types of answers (i.e.: multiple-choice versus true/false) and those details will be implemented elsewhere. Consult the UML class diagram and add implementation to the Question class based on these guidelines: • The isAnswerCorrect() method is an abstract method. I.e.: It has no body. • No further notes are given about the other members (fields, constructors and methods), so use the UML class diagram to guide your implementation. Part 4: MultipleChoiceQuestion class The MultipleChoiceQuestion class adds extra functionality inherited from the Question class to represent one multiple-choice question for a test. It adds extra details about the answers. Consult the UML class diagram and add implementation to the MultipleChoiceQuestion class based on these guidelines: • The isAnswerCorrect() method is overridden from the Question class. It returns true if “correctAnswer” and “chosenAnswer” are the same, otherwise false. • The constructor accepts “answer1”, “answer2”, “answer3” and “answer4” separately, but they are stored together as “answers” of type String[4]. • Field “chosenAnswer” takes a default value of ‘a’, which is the first answer. • No further notes are given about the other members (fields, constructors and methods), so use the UML class diagram to guide your implementation. Part 5: TrueFalseQuestion class The TrueFalseQuestion class adds extra functionality inherited from the Question class to represent one true-false question for a test. It adds extra details about the answers. Consult the UML class diagram and add implementation to the TrueFalseQuestion class based on these guidelines: • The isAnswerCorrect() method is overridden from the Question class. It returns true if “correctAnswer” and “chosenAnswer” are the same, otherwise false. • Field “chosenAnswer” takes a default value of ‘true’, which is the first answer. • No further notes are given about the other members (fields, constructors and methods), so use the UML class diagram to guide your implementation. Part 6: QuestionFinder interface The QuestionFinder interface provides the containsQuestion() method used in the QuestionBank and Test classes. It provides one method with the following definition: public default boolean containsQuestion(String questionID, ArrayList questions) { ... } The method returns true if the “questionID” is found in the “questions” ArrayList, otherwise false. This method is implemented as a concrete method. Concrete methods are allowed in interfaces provided that the default keyword is used. This is a new feature added to Java version 8. 7 Implement the containsQuestion() method in the QuestionFinder interface based on the above guidelines.
