play with this a little...
it has the basics,
best i can do right now...
import java.io.* ;
import Car ;
class MilesPerGallon
  public static void main( String[] args )
      throws IOException
    BufferedReader userIn =
        new BufferedReader(
        new InputStreamReader( System.in ) );
    String line;
    int    startMiles, endMiles;
    double gallons;
    System.out.println("Enter first reading:" );
    line = userIn.readLine();
    startMiles = Integer.parseInt( line );
    System.out.println("Enter second reading:" );
    line = userIn.readLine();
    endMiles = Integer.parseInt( line );
    System.out.println("Enter gallons:" );
    line = userIn.readLine();
    gallons = Integer.parseInt( line );
    Car car = new Car(
        startMiles, endMiles, gallons  );
    System.out.println( "Miles per gallon is "
        + car.calculateMPG() );
}
