Ques from KAM

[Meenakshi_Agarwal]

Hi all!
I have a doubt regarding the Exercise Ques.in KAM 10.23(Pg:321).
10.23) Which of these parameter lists have a
corresponding constructor in the StringBuffer
class?
a) ()
b) (int capacity)
c) (char[] data)
d) (String str)
answer given in the book is
(a),(b) and (d)
The StringBuffer class does not have a constructor
that takes an array of char as a parameter.
My doubt is:
Doesn't the overloaded method append() of StringBuffer
class has a signature as follows:
StringBuffer append(char[] str)
It is also given in the KAM (Pg:318) under the section
Appending, Inserting, and Deleting Characters in String Buffers.
Is the answer given wrong? Should not it be
(a),(b),(c)and(d).
Please clarify.
Thanks in advance!

Hello Meenakshi!
The answer given is correct, it should be (a),(b) and (d). These are the only 3 constructors the StringBuffer class accepts.
You are also correct about the append(char[] str), but this is Not a constructor, it is a method provided by the StringBuffer class.
Regards

Thanks Navin and Dominic!
It was silly of me to overlook the word 'constructor' in the question. Thanks again for your prompt reply. With this I have also realized the amount of concentration that one needs to put in, for this Exam in particular.
Thanks once again.
