Question

Java code that implements the following scenario:

There are three classes one for quizzes one for questions and a main.

One quiz question can appear in a number of quizzes. If a quiz question is updated, it's important that all quizzes then reflect that change. Questions are true or false questions, which have a prompt and a correct answer. There are also automated quiz-testers which have a unique id and can attempt to answer questions. To do this they always check the prompt of a question for a particular string and answer true if they find it, or false if they do not. This string is customized for each quiz-tester. It should be possible to get the score a quiz-tester receives on any given quiz. It also should be possible to get an overall average quiz score, which should be calculated by treating each quiz score (NOT question!) equally and finding the average of all quizzes in the system.

Completes the following methods in the main:

creates a question with these parameters -- (int id, boolean answer, String prompt)

Returns the QuestionPrompt from the given question id number

Creates a quiz from a given id number

adds a question to a quiz given the question id number and the quiz id number

updates the questoin from the given -- (int questionId, boolean answer, String prompt)

from the quiz id returns the quiz

Creates a QuizTester from -- (int id, String searchString)

GetQuizTesterScoreOnQuiz( int quizTesterId, int quizId)

GetQuizTesterOverallScore( int quizTesterId)
