1. Create an interface Icar that has the following methods:                                        

●      Method “calculateTax()”, returns the type float: calculate the tax of the car.

●      Method “calculatePrice()”, returns the type float: calculate the total cost of the car.                                                                      

●      Method “getInfor()”, returns the type void: display the information of the car.

2. Create a class Car inherit from interface Icar.                                                                                         [6]

Declare fields has access modifier as private use for properties: name, producer, year, seat and rootprice.                                                                          

●        Create two constructors and all method get/set for its attributes

●        Implement method calculateTax() to calculate the Tax as follows:            

○    If the car has under 7 seats then tax = RootPrice * 60%.

○    Else tax = RootPrice * 70%

●        Implement method calculatePrice() to calculate TotalPrice as follows:      

○    TotalPrice=RootPrice  + Tax

●        Implement method getInfor() to show the information as follows: .... car produced by ... in ... has ... seats with the total price is ....$. Variable includes :name of the car, the name of the manufacturer, year of production, seats and TotalPrice (For example: Ford car produced by Ford in 1997 has 4 seats with the total price is 20000 $).                                                                               

3. Declaring class LuxuryCar inherits from class Car and adding follow attrubtes :                           

private float specialRate;

●        Create two constructors and all method get/set for its attributes

●        Override method calculatePrice to calculate TotalPrice as follows :          

TotalPrice = RootPrice + Tax + RootPrice * specialRate

●        Overload method calculatePrice with 1 parameter named “transportCost” with type float. It calculates TotalCost as follows:                                                   TotalPrice = RootPrice + Tax + RootPrice * specialRate + transportCost.

4. Create a class named Test.                                                                           

●        Declare and initialize 1 instance named “myLuxuryCar” of class LuxuryCar.

○    Input Name, Producer, Year, Seat, rootPrice from the keyboard (Catch exception when input value). Display the contents of this LuxuryCar.

○    Calculate TotalPrice in case transportCost is $ 20,000, and display it.
