I keep failing to pass the following requirement. Can anyone give me some guidance? "The draw(Game) method must call the setCellValueEx(int, int, Color, String, Color, int) method on a Game object with the following arguments: x, y, Color.NONE, APPLE_SIGN, <color of the apple>, 75. (Replace <color of the apple> with a color you like, for example, Color.GREEN)."

can someone explain to me why apple.draw(this) works? I mean I get that apple.draw(apple) is wrong since apple is of type Apple while draw(Game) expects Game type but why does "this" work? I thought "this" refers to the object that's calling the method which is apple so "this" should be of type Apple too?

Hi! No, the 'this' keyword refers to the class.

@Tara this is the first time i see that "this" refers to a class . I used to know that it refers always only to the current object

"this" refers to the object of SnakeGame class, because SnakeGame inherit Game class，so "this" can also call the setCellValueEx() method.

Hi team, We are unable to meet the below requirement. Could you please elaborate about the same. The draw(Game) method must be called on the created apple. Pass this to the method.

it can be a little confusing, the right sentence i think will be: Pass 'this' to the method.
