Interface is a syntactical contract that all the derived
classes should follow.

public interface MotorStateObject
{
int State{ get;}

void Running();

void Stop();

int Speed { set;get; }

}
public class Car : MotorStateObject
{ .....
}

public class Bike : MotorStateObject
{......
}

public class Bus : MotorStateObject
{......
}

public class MotorState()
{
public void applybrake(MotorStateObject Object)

{
MotorStateObject.Stop();
}
}
