I couldn't find an errata for SCJP 6, so I don't know if this was previously addressed.

On page 298 of the SCJP 6 book Table 4-1
5th row - throws a compile time error , does not print false

but the table says the result is false.

Foo[] fa = new Foo[3];
//Following throws compiler error, wont print false
System.out.println(fa instanceof Foo);
System.out.println(fa instanceof Bar);
System.out.println(fa instanceof Face);

Neither you provided the code snippet nor URL and I don't have a book to refer, So provide the code !!

Rashmi you are correct here, this should be an errata.

Even foo[1] will only return true when
foo[1]=new Foo(); means foo[1] is assigned Foo object.

here is code Sagar:

OK, I got it now ,
This lines throws the errors :



foo is an object on Foo[], an array object.

I thought it was obvious that this post was made only for those who have the book.

I should have made it more obvious. No regrets.

Ok, fine.
Those who got that book, fine for them. I like to know the question (code), to learn things..(Not for only me, for other fellow Ranchers too). So its better, to provide the code, so that peoples like me ( who don't have a book ) gain some knowledge.

I got the book because it explains things clearly in a way I can understand. It is hard to understand things out of context.
 
I agree. Here's the link: http://aspose.com/file-tools
