Hi all !

Can anyone please sort out my problem :

Problem : In Khaled book the syntax of constructor is written as follows :
<constructor header> (<parameter list> )
{
<constructor body>
}

And one restriction is given that : "Constructors cant specify exceptions in the header"

I revealed from this statement that you cant use throws caluse in constructor till i have attempted to compile the follwing piece of code which compiles fine

class exp
{
exp() throws Exception {}
}


So please explain me what the above statement is conveying.

Thanx.

Although my mock exam web site contains a mock exam set that is organized based on the chapters of Khalid's book, I have never actually seen his book. Instead, my primary source of information for my mock exams was the Java Language Specification, so I can direct you to the chapter of the JLS that covers constructors.

The term "constructor header" appears to be something that Khalid defined to simplify the topic, so I can't offer any more information on that term beyond what appears in his book. All I can say is that a constructor declaration can include a "throws clause".

In the current 2nd Edition (for SCJP 1.4) of the book it has (p 117 section 4.4):



I cannot see any mention of a restriction regarding exceptions.
