Class: Vehicle

• Create an abstract class based on the following Unified Modeling Language Class Diagram.
• In the default constructor set Range to -1, and Capacity to -1.
• Abstract method Fuel Efficiency.

  Vehicle

  • range: double (units: miles)
  • capacity: double (units: gallons)
  • Vehicle()
  • Vehicle(range: double, capacity: double)

  • setRange(double): void
  • getRange(): double
  • setCapacity(double): void
  • getCapacity(): double
  • fuelEfficiency(): double

Class: Car (subclass of Vehicle, implementation of Comparable)

• Create a class based on the following Unified Modeling Language Class Diagram.
• In the default constructor set Airbags to 1, Convertible to false.
• Calculate the Fuel Efficiency using this formula - Overriding Abstract Methods. Display an appropriate message if the fuel efficiency should not be calculated.
• Compare To should return 100 if the fuel efficiency of object is smaller, 0 if the fuel efficiency is equal, -100 if the fuel efficiency is larger.

  Car

  • airbags: int
  • convertible: boolean
  • Car()
  • Car(airbags: int, convertible: boolean)
  • Car(airbags: int, convertible: boolean, range: double, capacity: double)

  • setAirbags(airbags: int): void
  • getAirbags(): int
  • setConvertible(convertible: boolean): void
  • getConvertible(): boolean
  • fuelEfficiency():double
  • compareTo(object: Car): int
