Two Cars

Here is the program with a few more blank lines:

class Car
{
  . . . .
}

class MilesPerGallon
{
  public static void main( String[] args ) 
  {
    Car car1 = new Car( 32456, 32810, 10.6 );
    System.out.println( "Miles per gallon of car 1 is " + car1.calculateMPG() );

    Car car2 = new Car( , ,   );

    System.out.println( "Miles per gallon of car 2 is " + car2.calculateMPG() );

  }
}
