Hi everybody,

Today I finally (after 6 weeks and 2 days) got my SCJD result back. I am glad to say I passed! My final score is 378 out of 400.

SectionMax PointsActual Points
---------------------------------------------
General Con: 100 90
Documentation: 70 70
OOD: 30 30
GUI: 40 28
Locking: 80 80
Data Store: 40 40
Network Server: 40 40
Total: 400 378

I am not sure why I lost so many points on the GUI, but other than that I am quit happy.

Thanks to everybody around here for their support and advice. A special thanks goes out to Andrew Monkhouse for his great book and good feedback on this forum.

Best regards,
Jethro

Congratulations with your SCJD! When did you do your essay exam?
I documented my decision while developing. If you do it at the end there is a big chance you forget things.
Your welcome, good luck and have fun while experimenting!
Off course it is not supposed to be slow, but if you want to find out the problem I suggest experimenting with the FileChooser. One of the experiments you might to do is trying it without the FileFilter. Making an SSCCE (Short, Self Contained, Correct (Compilable), Example) will also help.
Is it also slow if you remove the FileFilter?
Personally I feel this approach is a no-go. Making fields public could lead to all kinds of problem (thread safety, no way to validate the values, etc.). However, if you feel like taking the risk than document your decision.
And off course you can configure the logger way in a lot of different ways while you can not do that with System.out.
I did not use assertions.

As to logging: I would really recommend using this. It helped my find a few nasty bugs, especially on the server side. Using logging greatly improves your feel on what the application is doing and it which order. I think this will also improve the life of the grader, because they might be able to use your log statements in order to assess what your application is doing.
Yes I know, I'm just impatient, because I really want to know my if I passed :-)
Yes you are right, a lock cookie is used by a client.
I am waiting for over 5 weeks now
A lock cookie should be used to check if the Thread that accesses a certain record hold the lock to that record. In your lock() method you should generate such a cookie, you could use System.nanoTime() for this (for example).
Congratulations!

I am waiting on my results for over a month now to...

Thanks!

Congratulations on your certification. What will be the next certificate which you are going to pursue?

I have done my essay exam a small three weeks back, how long did you had to wait until you received your results? I am assuming you saw your results on the "https://www.certmanager.net/"; under the "Test history" button?
