PLEASE HELP WITH THIS PROGRAM. JUST NEED HELP WITH MODIFICATIONS TO A PROGRAM THAT IS ALREADY OUT THERE!!!

So this is a programming challenge from the tony gaddis starting out with java book. PC 10, from chapter 8. Following are the instructions.

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 MODIFICATIONS I NEED HELP WITH ARE: your program will consist of four files, two for the FuelGauge and Odometer, one for the Car, one to hold main(). You put the pieces together in Car in a single public method called simulate(). The latter makes calls to the FuelGauge and Odometer methods. In main() you create an instance of Car and call simulate(). Car is an aggregation of FuelGauge and Odometer.

Your help will be greatly appreciated. If you would like the code for the first part of the program please let me know!!

10. Car Instrument Simulator 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 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. e 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. The odometer Class: This class will simulate the car's odometer. Its responsibilities are as follows: e 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 traveled. (The car's fuel economy is 24 miles per gallon.) Demonstrate the classes by creating instances of each. Simulate filling the car up with fuel and 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
