Question 

Write code for an Invoice class for a car sale. Printing an object of the Invoice should print the
details about the seller, the buyer, the dealer, the date of transaction, the car being sold, the purchase and selling price, the commission earned by the dealer, sales tax, and the total price of the car (calculated given the details in Question 3 part 3). A generation of the invoice object should set the isSold variable of the car class to true. You do not need to write code for any other classes

 

Syntax of the Q3 code is given below:

import java.util.*;

 

class Car{      //class car

    String[] name;

    int reg_number,eng_number, chassis_num,status;

    String[] city, model, color, date_reg,date_arr,type;

    float price;

 

    float abstract calculate (float price);

}

class Dealer extends Car{   //inherits from Car

    String[] deal_name, deal_id, deal_add, deal_pno;

    float dealer_com ;

    float abstract calculate (float price)

    {   dealer_com= 0.01*price + 0.01*price;

    }

    return dealer_com;

}

class person {

    String[] name, address, p_no, email;

}

 

class Seller extends Car{   //inherits from Car

    person p= new person();

    float seller_price,sale_tax;

    float profit;

    float abstract calculate (float price)

    {

        if(purchase_price>sale_price)

        {   

            profit= purchase_price-sale_price;

            sale_tax=sale_tax-0.17*profit;

            return profit;

        }   

        else

            return price;

    }

 

}

 

class Buyer extends Car{   //inherits from Car

    person p= new person();

    float total_amount;

    int f;

    seller s= new seller();

    float abstract calculate (float price)

    {   f=s.calculate(price);

        if(f==price)

            return price;

        else    

            retun price+f;        

    }

 

}

class Invoice{

    public static void main(String[] args)

    {

        

    }

}

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.
