Provide a different implementation of ChoiceQuestion. Instead of storing the choices in an array list, the addChoice method should add the choice to the question text. For this purpose, an addLine method has been added to the Question class. /** A question with multiple choices. */ public class ChoiceQuestion extends Question { // Add any needed instance variables, but don't store the choices // The choices should be added to the text of the superclass /* code goes here */ /** Constructs a choice question with a given text and no choices. @param questionText the text of this question */ public ChoiceQuestion(String questionText) { /code goes here */ } /** Adds an answer choice to this question. @param choice the choice to add @param correct true if this is the correct choice, false otherwise */ public void addChoice(String choice, boolean correct) { /* code goes here */ } }
