Question

Add a class NumericQuestion to the question hierarchy of Section 9.1. If the response and the expected answer differ by no more than 0.01, then accept the response as correct.

I add a class like this but the second question's result is wrong. To satisfy upper conditon, how can I fix it?

import java.util.Scanner;

public class Question
{
   private String text;
   private String answer;
  

   public Question()
   {
       text="";
       answer="";
      
   }
   public static void presentQuestion(Question q)
   {
       q.display();
       System.out.print("Your answer: ");
       Scanner in =new Scanner(System.in);
       String response =in.nextLine();
       System.out.println(q.checkAnswer(response));
   }
  
   public void setText(String questionText)
   {
       text=questionText;
   }
  
   public void setAnswer(String correctResponse)
   {
       answer=correctResponse;
   }
  
   public boolean checkAnswer(String response)
   {
      
       return response.replaceAll("\s+","").toLowerCase().equals(answer.replaceAll("\s+","").toLowerCase());
   }
  
   public void display()
   {
       System.out.println(text);
   }

}

Explanation / Answer

The reason is the second question you mentioned:

second.setAnswer("3.141593") // this is string which actually calls the string argument function of question class.

Change:
Question second=new Question();
second.setText("pi?");
second.setAnswer("3.141592");

To:
NumericQuestion second=new NumericQuestion();
second.setText("pi?");
second.setAnswer(3.141592);
