Question 3: 1. Explain the importance of method signature in method overriding. 2. The system might want to use an overridden method (function) with a common signature across the relevant classes Seller, Dealer, Buyer, and distinct classes Car and Invoice for maintaining the finances. Details of the classes can be seen in Table 1. Explain with proper syntax as to how this can be achieved using object-oriented programming. 3. Write Java code (for the methods only) that implements the method with the same signature for each class with the following details: a. Calculates the commission earned by the dealer. A dealer charges 1% commission each to the buyer and seller on sale price of the car. b. The profit or loss for the seller. A seller earns profit (incurs loss) computed as the difference between the sale and purchase price of the car. Sales Tax is deducted at the rate of 17% on the profit earned. No sales tax is charged in case of loss. The method should display an appropriate message accordingly. c. The total amount paid by the buyer.
