Class Definition

Here is the miles per gallon program, now with a skeleton for the Car class. To keep the program short, user interaction has been left out.

class Car
{
  // instance variables


  // constructor


  // methods

}

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

The source file must be named MilesPerGallon.java after the name of the class that contains main().
