Has To be in Java

For this assignment, you will design a set of classes that work together to simulate a

cars fuel gauge and odometer The classes you will design are the following:

The FuelGauge Class: This class will simulate a fuel gauge. Its responsibilities are as

follows:

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 I 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 I gallon, if the amount of fuel is

greater than 0 gallons. This simulates burning fuel as the car runs.

The Odometer Class: This class will simulate the car's odometer. Its responsibilities are

as follows:

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 FuelGauge object. It should decrease the FuelGauge object's current amount of fuel by 1 gallon for every 24 miles travled. ( The cars fuel economy is 24 miles per gallon)

--Demonstrate the classes by creating instances of each. Simulate filing the car up with the fuel, and then run a loop that increments the odometer until the car runsout of fuel. During each loop iteration, print the car's current milage and amount of fuel.

--The Ouput-- should look in this format

Milage: xxxx

Fuel level: # of gallons

(This format should be repeated)

           }
           else
