Sure.
Here is the program with a few more blank lines:
import java.io.* ;
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 "
+ ____.calculateMPG() );
}
}
