Implement a class Car, each of whose objects has a certain amount of gas in the gas tank, uses a specific amount of fuel per mile, and has a gas tank with a certain capacity.

Provide a constructor that specifies the miles per gallon for the car. Define a method named drive that allows the car to be driven a certain distance and decrements the fuel supply appropriately. Also define a method named refuel that adds fuel to an existing Car object. Be sure to define appropriate accessor and mutator methods for the class.

Test your class using a program that instantiates two different cars, one with a fuel efficiency of 32 miles per gallon and a 12-gallon tank, and one with a fuel efficiency of 21 miles per gallon and a 22-gallon tank. Each car is driven 121 miles with 10 gallons of fuel. Compute the amount of fuel remaining in each car.
