K&B inner classes Q.2

[Neha Daga]

class Boo {
   Boo(String s) { }
   Boo() { }
}
class Bar extends Boo {
   Bar() { }
   Bar(String s) {super(s);}
   void zoo() {
   // insert code here
   }
}

Which create an anonymous inner class from within class Bar? (Choose all that apply.)

A. Boo f = new Boo(24) { };
B. Boo f = new Bar() { };
C. Boo f = new Boo() {String s; };
D. Bar f = new Boo(String s) { };
E. Boo f = new Boo.Bar(String s) { };

the answer they say is B and C.
B is fine with me but how come C is a correct answer its creating an anonymous class from within Boo not from Bar.

Because you are inserting the code in the code for the Bar class. Since the code is in the Bar class, it will be an anonymous inner class in Bar.

oh yes , I didn't see that......thanks

Because the line is inserted in the class Bar . The other possibilities are not possible because they use an argument in the constructor which is not possible for an anonymous class.
