3. In the App class you should populate your tree of data starting with 3 Apartments, each rental has 4 renters, and each
renter has 3 items. Save the data by calling the save for each apartment. This should cascade down the tree. Clear
the rentals ConcurrentHashMap and then reload the entire structure (code below) and print the list
while(raf.getFilePointer() < raf.length())
Apartment a = new Apartment(raf);
rentals.put(a.apartmentId, a);
}
