Подскажите в чем проблема плиз(

System.out.println(Dream.HOBBIE.toString());

вместо
 System.out.println(new Hobbie().toString());

public class Solution {

    public static void main(String[] args) throws Exception {

        System.out.println(Dream.HOBBIE.toString());
        System.out.println(new Hobby().toString());
    }

    interface Desire {
    }

    interface Dream {
          public Hobby HOBBIE = new Hobby();
    }

    static class Hobby implements Desire, Dream {
        static int INDEX = 1;

        @Override
        public String toString() {
            INDEX++;
            return "" + INDEX;
        }
    }
