public abstract class SimpleQuestion

extends java.lang.Object

implements Question

Basic and incomplete implementation of the Question interface, which you can subclass at will to create new types of Questions.
In your sub classes, you should define some Fields to store the possible answers (*not* Answers), and override isAnswerValid and makeNewAnswer, and (most probably) save, delete and the 2 usual constructors.
