class Question (id:Int, ans:Boolean) {//id and ans are parameters to the constructor
//They are NOT class variables.  But if I had declared them with var id:Int, say, then
//they WOULD be class variables

    //modified, I am essentially locking an object in place.  An
    //object of this class, once constructed, cannot be modified
