Suppose you are working on an object-oriented module for the sale and purchase of
sacrificial animals. Major Classes are Seller, Dealer, Animal, Buyer, and Invoice. Details of the classes
can be seen in Table 1. Note that the system does not store information about individual person, apart from
the Seller, dealer, or a buyer. Write Java code for the class declaration, instance variables, and constructors
for all the classes. Use inheritance and composition where required. You can create new class(es) if needed,
with explanation in comments.
