Instance Variables for Fleet

The long-lasting state of a Fleet object is held in its two instance variables. These variables refer to Car objects. The documentation for Fleet might look like this:

---

Fleet

A class that holds two Car objects.

Constructors

Fleet( int Car1StartOdo, int Car1EndingOdo, double Car1Gallons, 
       int Car2StartOdo, int Car2EndingOdo, double Car2Gallons )

Creates a new instance of a Fleet object with the starting and ending odometer readings and the number of gallons of gas consumed for each car.

Methods

double calculateMPG()

Calculates and returns the average miles per gallon for the fleet.

---

The constructor builds the two cars of the fleet. SEach car needs three initial values. So the constructor for Fleet has a total of six initial values. (There are other more elegant ways to do this, but let us do it this way for now.) Here is a short main() that constructs a fleet:

class FleetTester
{
  public static void main ( String[] args)
  {
    Fleet myCars = new Fleet( ____, ____, ____, ____, ____, ____  );
  }

}
