anonymous inner class

[GM Shobha]

1 class Boo{
2 Boo(String s){}
3 Boo(){}
4 }
5 class Bar extends Boo{
6 Bar(){}
7 Bar(String s){super(s);}
8 void zoo() {}
9 Boo f= new Boo() {String s;};
10 }
Does code in line no. 9,creates an instance of Boo or an instance of subclass of Boo?
This is Q.no 4 in self test on inner classes from Kathy&Bert book.

The topic for this thread should give you a big clue. If f is an anonymous inner class then it can't be an instance of Boo or it would have a name and wouldn't be anonymous, wouldn't it?
