hi
I am not sure what you guys mean by the SCJP Beta. I wrote the
SCJP exam last week as well. I haven't yet gotten the certificate but Sun's site says that it can take up to 30 days to receive the certificate.
I presume you are referring to the same exam I wrote.
You can also check under http://www.galton.com/~sun if your
certificate has been mailed already.

hi
I got that exception as well. I suggest you simple do
Object o[]=Arralist.toArray();
and then try converting to Strings later.
by calling toString(); cheers

hi
How many do you think have done the Sun Certified Java Architect exam (both new and old one). How do you guys think the market values these certifications. Especially the Programmer/Developer one.

hi guys
I have just finished my SCJP2 and am staying in Cape Town, South Africa. I am wondering if there is someone out there who is from South Africa an preparing for the SCJD. We could organise and work together on this. I haven't yet purchased my voucher but should do this as soon as possible. I am looking at finishing this up by end of January 2001.
Cheers

hi guys
I didn't have much time to report on my experiences with the
exam itself. I will take this time to share my experience with
the exam.
I can't exactly remember the breakdown of all exams but here is
some tips.
1. answer the questions u know for sure first and come back to
the tricky ones later.
2. don't waste more than 1 minute on one question. if you can't figure out the answer after 1 minute then move on.
3. with respect to I/O classes, make sure you know that InputStream/OutputStream are abstract and thus can't be newed.
4. All Readers/Writer classes (i.e those classes which ends with
either Reader/Writer) are character oriented classes and thus the only way to assign such byte oriented streams such as FileInputStream/FileOutputStream to character oriented streams is through the InputStreamReader/InputStreamWriter classes.
5. Take a look into how Garbage collection works especially
where all references to an Object in an Array have been lost.
6. Collections API, you simply need to know which interfaces/classes store objects that are unique. which ones
for ordered objects, which ones for key/value pairs.
7. String is immutable, so if I create String s1="Desmond";
what ever I do to s1, I will still get "Desmond" unless I null the reference.
8. you can't do + operations to StringBufferes!!
I don't have much time to continue, but I will keep contributing to the forum. good luck those who are taking the exam.
Cheers
