Now I've read all the other entries (I didn't want to read them before I voted in case I was influenced), I realise how many different ideas there are and how many different opinions.

To try to please even more people than by picking one picture, couldn't you have a Do-It-Yourself cover? You could have a blank space in the centre of the front cover and sell the book with a set of stickers, one of each of the pictures. Everyone could then choose their own favourite and stick it on their book. Each copy would then be personalised.

Well, it's always hard making a decision of any kind, so I'm definitely going to need a copy of this book to make design decisions a bit less stressful. Having said that, I have a vested interest in making sure that the cover appeals!

Tackling this on an emotional level, I was immediately intimidated by all those people with such big heads!! How can the book be of any use to me (a small-headed person, as you might have gathered) if it's covered by a big-head? Not only that, but some of the angles the pictures were taken at gave me a sense of vertigo. Oh help!

Having eliminated the big-headed, scary people, I was looking for a comforting soul-mate. Someone who looked caring, supportive and reassuring.

I have chosen P: Biker Couple as they look the friendliest and make a nice couple.

I think you may want to do the String comparison using equals() rather than '==', eg. data.equals("ind").
You will probably want another 'else' for when the combo selection goes back to "a".

You can get round this by using the FocusAdapter class. This implements the FocusListener for you, but with empty methods.
This means you just need to subclass it and write the methods that you're interested in.

IMHO, other than the Sun free practice questions, I wouldn't bother with any others. If you've worked your way through all of Dan's and Marcus's mocks and your scores are OK, go for it!
Good Luck!
I was too mean to go out and buy a new book for the exam, but I already had O'Reiily's 'Java in a Nutshell' and I found this a really good concise reference.
It probably won't teach you Java from scratch, but I still use it as a reference after passing the exam.
Hi Veena,
The Sun site will tell you what is on the exam, but quoting from it:
Section 7 (second bullet) 'Recognize conditions that might prevent a thread from executing.'
Section 9 (first bullet) 'Make appropriate selection of collection classes/interfaces to suit specified behavior requirements'
From this it sounds like you should do both! If it's any help, I didn't cover interrupt(), but did do Iterator and ListIterator in Collections, and I passed. Other people may have different ideas though.
Good Luck,
Helen
I did my exam in a UK Prometric test centre, and they wanted to know the details of my Sun voucher before I booked the exam. They were happy then to take a credit card payment and arrange the exam time over the phone. In fact, I changed the exam date about a week before I was due to take it and they were fine with this.
Good luck with the retake.
Hi,
I've never seen strictfp used in any real-world coding but I understand that it is used to indicate that any floating-point maths must conform to the IEEE 754 standard, so all values must be expressed as float and double and any internal values can't use platform-dependent formats that may give you extra range or precision. This is so that you can predict what any rounding errors will be.
As long as you know it can be applied to a class or method only, this is all you'll need for the exam.
Whoa! I've been feeling smug all day that someone thinks I'm a lady!
That aside, I've worked right through this example and got it working, but I'm having problems getting a client to work on another machine. I've put in the RMI Security Manager and tried to lookup the service, but keep getting an Unmarshalling exception with a ClassNotFound one inside.
I've read lots of threads from people who have also had this problem but none of them have helped me fix it.
As you can see, the next instalment of this thread is eagerly awaited!

Hi Michael,
This was really great and I learnt a lot from it. Thank you.
Could you now add something about security policy and RMI as well?

At last, I've managed to get both sets of notes. I haven't changed anything, but each day I've tried to download them and today, it finally worked.
I haven't changed anything at all in my set-up so I still don't know what the problem was, but it obviously pays to be persistent. Now to do some study!
Thanks for everyone's help,
Helen

Well, the latest in this saga is that I can now access Michelle's notes, but not Ken's. I haven't changed anything at all, but it suddenly works (partially!).
A very clever colleague of mine has looked at the corrupted file I've downloaded and says that it looks like it has been divided into 30k packets and the first has been lost so the rest of the file has been mangled and glued together wrongly. (Sorry about the non-technical explanation, but you can tell this sort of thing is not my forte!) Apparently, without the first packet, TCP/IP just puts the packets together as received since the information about the correct order is in that first packet.
Does this make sense to anyone? Is there anything I can do about it?
Thanks for all your help,
Helen

Hi,
Thanks for your suggestions; I tried several of them but still can't access the notes. I've updated Adobe Reader from 5.0 to 6.0 and it's made no difference.
I think the problem is with the download as the start of the WCDStudyNotes-Michelle.pdf looks like this for me:

No mention of %PDF!
Does anyone have any more ideas?
Thanks for all your help,
Helen
