Which one is the main calling?

[sonir shah]

class Car
{
   public int gearRatio = 8;
   public String acelerate() {  return "Acelerate : Car";  }
}
class SportsCar extends Car
{
   public int gearRatio = 9;
   public String acelerate() {  return  "Acelerate : SportsCar";  }
   public static void main(String[] args)
   {
      Car c = new SportsCar();
      System.out.println( c.gearRatio+"  "+c.acelerate() );
   }
}

What will be printed when SportsCar is run?
Answer :8 Acelerate : SportsCar
I feel it should print :-
9 Acelerate : SportsCar, since in the main you are saying "new SportsCar()"
Please explain?

The varibles are called by reference type and not by object type. Here the refrence is of type Car so Car.gearRatio will be printed

When accessing fields, the compile-time type counts (here c.gearRatio will be the gearRatio of class Car), while when accessing methods the run-time type is taken into account (you got that one )
