private enum member within same file, is it possible?

[Oskar Morganstern]

  

public class Bridge {
    public enum Suits {
        CLUBS(20), DIAMONDS(20), HEARTS(30), SPADES(30),
        NOTRUMP(40) { public int getBidValue(int bid) { return ((bid-1)*30)+40; } };

        Suits(int points) { this.points = points; }
        private int points;
        public int getBidValue(int bid) { return points * bid; }
    }

    public static void main(String[] args) {
        System.out.println(Suits.SPADES.points);
    }
}

  

How come I can access points?
something which I declared as private. I know that if I declared the enum in a separate file that it would not be visible. But why is it visible within the same file?
