It's because \u000a and \u000d are corresponding to CR and LF.
And translation of unicode caracters is done before compilation.
So, it means that compiler will first read your code and transform



into


and then will give a compilation error because, for the compiler, brackets must be closed on the same line, not the next one.


It's very well explained in the Java Language Specification (see � 3.10.4
http://java.sun.com/docs/books/jls/third_edition/html/lexical.html#3.10.4 )

I read it and noted some mistakes

page 454: �2 would be

... (unless you implement readObject) ...
in place of
... (unless you implement defaultReadObject()) ...

page 454: exam watch
If DataInputStream and DateOutputStream are nos in the exam, why not remove it from the objectives ? If people are not buying your book, they will use their to study something that is not in the exam.

page 459: selftest3
It's not indicated that IOException are catched somewhere. So, answer F could be considered as valid if we imagine that no catching occurs in the code.
Would be nicer to have
"Given that bw is a reference to ... and that all exception are catched"

page 465, first line

from a directory that has two subdirectories, "dir1" and "dir2"
in place of
from a directory that has two subdirectories, "dir1" and "dir1"

(last dir1 --> dir2)


page 468: selftest1
there are no explanation why start() return also 6 when length of String is 6 (means 0 to 5).


Vincent
I would like to say false,
because you can have Weak References to that object.
And if you have only weak reference to that object, the object is well eligible for garbage collection.

That would be a better formulation:

"An object become eligible for garbage collection when it exists no more strong references pointing to that object"

(after correction of my english :-) )

Vincent
Reason is explained at begin of page 450

It's almost as if the methods were defined in the Serializable interface, except they aren't. They are part of a special callback contract the serialisation system offers you that basically says, "If you (the programmer) have a pair of methods matching this exact signature (you'll see them in a moment), these methods will be called during the serialisation/deserialisation process



You have example of a code that will serialize/deserialize a Dog object on page 447-448 (the SerializeDog class)

Have a nice day.

Vincent
Congratulations.
Seems that it's harder to give existence to a book than to a baby !!!

Now that this book is done, what's the next one ?

Vincent
You can always look at here: http://javadiff.sourceforge.net/jdiff/reports/j2se142_j2se150b1/changes.html

You will have all diff at API level between J2SE1.4.2 and J2SE 1.5.0.

So, are abbreviations like "IMHO", "AFAIK", "BTW", "ASAP"... etc acceptable here?



Personally, I am a french speaker.
I know
IMHO means In My Humble Opinion
BTW means By The Way
ASAP means As Soon As Possible

But I have no idea of the meaning of AFAIK.

And I think that ASAP is not appropriate in a forum. Everything is urgent for everyone. So require a response ASAP is the same, IMHO , than posting a question.
I received my score report today.
And I would like to say that I am very happy to have been certified.

Reason why I am happy is the following:

When I was at school, if I want to pass and go to the next class, I needed to fill in those criteria:
  • Have a passing score of 59% (that's the same as for the Sun Certification)
  • Have at least 50% in each section (that's not the same as for the Sun Certification)



  • So, if it was a real exam, I would failed.
    But here, I success, with 50/72 ==> 69%

    The section where I failed (I mean less than 50%) is the Concurrency. And I completely agree with Sun.

    But I would like to say that, even if now I am a certified programmer, Sun would add the second criteria I mentionned. Have at least 50% for each section.

    Just my 2 cents.

    Hello everyone.
    I just looked at the database, and I can see that I am now a certified programmer.

    But I can't find my score (59% or 80% or 100%)
    And I really want to know which score I did.

    Where can I find such information ?

    P.S I also tried http://www.certmanager.net/sun_assignment/
    but as a first time user, it seems that they can recognize me.

    So, will be obliged to wait until 16 May ?

    It means that plenty of people are not yet ready to develop Java Application.
