Hi all,
Here is the question from K&B's CD:
class Bing {
Bing(String s) {};
Bing() {};
}
class Bang extends Bing {
Bang() {};
Bang(String bangS) {super(bangS);};
// inserted here
}
The question is which line can be inserted at // without produces error. One answer is
Bing b = new Bing() {"Foo";};
However, I am not understand why the above statement is OK. So I inserted this line and compile, following error is raised:
Bang.java:9: illegal start of type
Bing b = new Bing() {"Foo";};
^
Bang.java:9: <identifier> expected
Bing b = new Bing() {"Foo";};
^
2 errors
Why such error produced in compiling?
Thanks,
David

Hi,
I wouldn't like to contradict Kathy or Bert ,
and see a spell cast on me now that I'm preparing
for the SCJP...
...but the answer doesn't look correct,
I can't compile it either, maybe it should have
been: Bing b = new Bing("Foo");
greetings,
Gian Franco

Hi David,
From what you've posted it looks like a syntax error
As Gian has pointed out, it should either be
Bing b = new Bing("Foo");
or
Bing b = new Bing();
You may want to check their Errata page.

Cheers,
-Jarrod

Hi Jarrod,
I did not find errata page related to this question. It seems that it is a typo now
