Quention on Anonymous Inner Classes

[Meghna Bhardwaj]

HI All,

I am preparing for the SCJP 6 and my question is in the below example:
This is from the K&B book, chapter 8, Pg 666, Question 4.

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

}
 

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

The correct options are B and C, and until now it all makes good sense to me. But I coded this in eclipse and here is what I tried:

    Boo f = new Bar(22) {   Bar(int x){}  };
      Boo f = new Boo(24) { Boo(int x ){} };
 

So I am creating a new anonymous inner class and providing a constructor inside it which will accept an integer.
This gives me compiler error. I am wondering why it is possible to only Override the super constructors
and NOT overload them like I am trying.
Any help will be much appreciated. Thanks.

Meghna its not about overloading or overriding constructors. Anonymous inner classes can't declare a constructor whatsoever. So you cannot create a constructor in an Anonymous inner class.
