Modified Files:
added toXML and fromXML functionality to Exam so that
it now can store Results if they are present in Exam.
Had to modify Student Class and overwrite equals and
hashCode method to be useable in Exam HashMap with
Results. As the HashMap couldn't be used after fromXML
as the objects hadn't the same hashCode.
