Answer 2

Change this line :
System.out.println(car.setColor());
to
System.out.println(car.getColor()+"");

Hi,
you cannot print out setColor() since it doesn't have a return value, it only changes the color (and it needs an argument). If you want to print out the cars color, you need to use the getColor() method.
