Major Classes are Seller, Dealer, Animal, Buyer, and Invoice. Details of the classescan be seen in Table 1. Note that the system does not store information about individual person, apart fromthe Seller, dealer, or a buyer. Write Java code for the class declaration, instance variables, and constructorsfor all the classes. Use inheritance and composition where required. You can create new class(es) if needed,with explanation in comments.Table1:AttributesType (Cow, Goat, Lamb etc), a unique identification tag, color, weight, price per kg, thedate of arrival of the Animal to the dealership, service charges, and whether the Animal issold or not.dealer's name, dealer's id, dealer's address, the dealer's phone number, and the commissionrate. The dealer object also keeps track of the Animals that the dealer has. It includes amethod that calculates the earning of the dealerSeller's name, id, address, contact, profit rate and sales tax rate. Includes methods tocalculate the sales tax on the profit and after tax profit of the sellerName, id, address, contact.
