Problem Description

For this assignment, you will design a set of classes that work together to simulate a car’s fuel gauge and odometer. The classes you will design are as follows:

The FuelGauge Class. This class simulates a fuel gauge. It’s responsibilities are:

– To know the car’s current amount of fuel, in gallons.

– To report the car’s current amount of fuel, in gallons.

– To be able to increment the amount of fuel by 1 gallon. This simulates putting fuel in the car. (The car can hold a maximum of 15 gallons.)

– To be able to decrement the amount of fuel by 1 gallon, if the amount of fuel is greater than 0 gallons. This simulates burning fuel as the car runs.

FuelGauge

+MAX_GALLONS=15:int

-gallons:int

+FuelGauge(g:int)

+getGallons():int

+incrementGallons():void

+decrementGallons():void

The Odometer Class. This class simulates the car’s odometer. It’s responsibilities are:

– To know the car’s current mileage.

– To report the car’s current mileage.

– To be able to increment the current mileage by 1 mile. The maximum mileage the odometer can store is 999,999 miles. When this amount is exceeded, the odometer resets the current mileage to 0.

– To be able to work with a FuelGuage object. It should decrease the FuelGauge object’s current amount of fuel by 1 gallon for every 24 miles traveled. (The car’s fuel economy is 24 miles per gallon.)

Odometer

+MAX_MILEAGE:int=999999

+MPG:int=24

-mileage:int

-setPoint:int

-fuelGauge:FuelGauge

+Odometer(m:int

                       fg:FuelGauge)

+getMileage():int

+incrementMileage()void

FuelGauge

+MAX_GALLONS=15 int

-gallons:int

+FuelGauge()

+FuelGauge(g:int)

+getGallons():int

+incrementGallons()void

+decrementGallons()void

Demonstrate the classes by creating instances of each. Simulate filling the car up with fuel, then run a loop that increments the odometer until the car runs out of fuel. During each loop iteration, print the car’s current mileage and amount of fuel.
