Create two classes: Vehicle and
UnmannedVehicle. The class UnmannedVehicle is
a
subclass that extends the class Vehicle.
You are also required to write the driver class VehicleInformation,
which allows you to
test your implementation of Vehicle and UnmannedVehicle.
The following are implementation details for the classes you need
to implement (provided
when not self-evident):
• Vehicle class
o Private fields
String vehicleName
String vehicleManufacturer
int yearBuilt
int cost
o Public class constant field
int MINYEARBUILT equals to
1886 (as modern cars were invented in 1886)
o getter and setter methods depending on your program design
o void printInfo() method: Print out the
information of the Vehicle, including its
name, manufacturer, year built, and cost. An example of the output
of this
method is as follows:
Vehicle Information:
Name: RAV4
Manufacturer: Toyota
Year built: 2021
Cost: 38000
Note: As shown in the above example output, starting from the
second line,
each line has three spaces at the beginning.
• UnmannedVehicle class
o Extends the Vehicle class.
o Additional private fields: int SAE and int rating
§ SAE (level of automation) is between 0 and 5 and the rating
between 0
and 10.
o Public class constant fields for min and max SAE and, min and max
rating
o getter and setter methods depending on your program design
o Overrides the void printInfo() method of the superclass. The
method not only
print out the information of name, manufacturer, year built, and
cost, but also
print out the information about SAE and rating. An example of the
output this
method is as follows.
Vehicle Information:
Name: Model Z
Manufacturer: Tesla
Year built: 2022
Cost: 88000
SAE: 3
Rating: 7
Your VehicleInformation.java would use Vehicle and UnmannedVehicle
classes.
To do that, it has two methods Vehicle buildVehicle() and
UnmannedVehicle
buildUnmannedVehicle() that validates the information before
calling the
Vehicle/UnmannedVehicle constructor. Information to validate are
builtYear, cost, SAE and
rating. These methods will return the object reference if
successful, null otherwise.
Your main method should demonstrate the (tentative) creation of 2
unmanned and 2 regular
vehicles.
Below is the sample output.
Sample Output
Error: invalid yearBuilt. Object not created!
Vehicle Information:
Name: RAV4
Manufacturer: Toyota
Year built: 2021

Error: invalid sae. Object not created!
Vehicle Information:
Name: Model S
Manufacturer: Tesla
Year built: 2022
Cost: 80000
SAE: 2
