uggest a simple scheme for creating a new class SafeMember that would allow us to export a reference to a Member. The classes outside the system should be unaware of this additional class, and access the reference like a reference to a Member object. However, the reference would not allow the integrity of the data to be compromised. Remember that when designing the “Return Book with fines” use case, Member object is returned to the UserInterface to be able to display the member information such as owed fine. But this also means that the UserInterface can access all the Member methods. Your implementation of SafeMember class should prevent this.

Create all classes for entities. All classes must have at least a constructor, get and set methods for all private variables and a toString method. Create classes also for connection entities (e.g. orders, reservations, etc.) All information should be saved in files. When opening the program, all information from files must be loaded in array lists. Use an array list for every class. The program must have at least one menu where the user can choose the operations to work. You should at least have one class that inherits from another class. You should have at least one interface that is extended by at least 2 classes. You must use the interface methods in your program. You are allowed to use the GUI for this project. If not use JOptionPane You are allowed to use databases, instead of files.

- Customer This class should now implement the Comparable interface. Customer instances should be ordered by their last name, then first name, and finally the name of their associated building. toString() - Add this method that returns a String with the following format: <lastName>, <firstName> Reading This class should now implement the Comparable interface. Reading instances should be ordered by their timestamp. XmlHandler The following methods should be updated: startElement() - The handler logic should be modified such that it can now create and associate Customer, Building, Room, Device, and Reading objects. endElement() - Modify this method such that the current customer instance is added to the ArrayList of customers when a closing customer element is encountered.
