Here, have some sample code..

<sscce>
import java.beans.XMLEncoder;
import java.beans.XMLDecoder;
import java.io.*;

public class AnsweredQuestion {

 public String question;
 public String answer;

 public AnsweredQuestion() {
 }

 public AnsweredQuestion(
   String question,
   String answer) {

   this.question = question;
   this.answer = answer;
 }

 public void setQuestion(String question) {
   this.question = question;
 }

 public String getQuestion() {
   return question;
 }

 public void setAnswer(String answer) {
   this.answer = answer;
 }

 public String getAnswer() {
   return answer;
 }

 public String toString() {
   return "Q. " + question + "  A. " + answer;
 }

 public static void main(String[] args) throws FileNotFoundException {
   String filename = "qanda.xml";

   AnsweredQuestion[] qAndAStore = new AnsweredQuestion[3];

   qAndAStore[0] = new AnsweredQuestion(
     "Is an opal animal, mineral, or vegetable?",
     "Mineral.");
   qAndAStore[1] = new AnsweredQuestion(
     "What is the meaning of life?",
     "42.");
   qAndAStore[2] = new AnsweredQuestion(
     "What is your favorite color?",
     "Green, ..no, BLUE.  AAaaaargh!");

   XMLEncoder encoder = new XMLEncoder(
     new BufferedOutputStream(
       new FileOutputStream(filename)));

   encoder.writeObject( qAndAStore );
   encoder.close();

   XMLDecoder decoder = new XMLDecoder(
     new BufferedInputStream(
       new FileInputStream(filename)));
   AnsweredQuestion[] qAndARetrieve =
     (AnsweredQuestion[])decoder.readObject();
   encoder.close();

   for(int ii=0; ii<qAndARetrieve.length; ii++) {
     System.out.println(  qAndARetrieve[ii] );
   }
 }
}

This probably does not do what you need, but
further questions might require some more effort
on your part, or a consultant or help-desk.

Note that c.l.j.programmer is neither of the last two.

Note that I have not been following the thread closely
enough to ensure this is sample code according to
what Lew was saying.  I just churned it out because
I'm *extremely* bored.

That's fine.  There are a zillion ways to solve the problem.

I see that what you mean by a question is an organization of the information.
 I'd probably separate the issue of whether something is implemented via
checkboxes or a multi-select from the content of the information, similarly to
how Swing and JSF do it.

There are structures to hold the information.  One example is

Map< String, List<String>>

that can hold the question text and the list of answers (as for multi-select),
initially length 0 for unanswered questions.

The presentation of the text would be handled by separate layout components.

But your way seems OK, too.
