Congratulations! But somehow the score does not add up for me.

Getting someone to think and try something out is much more useful than just telling them the answer.

Yes you are right, the sum isn't correct...
Maybe a software calculation problem

In this case SUN failed... good for me

It was the orginal copy&paste info from certmanager database

I didn't really prepared myself. I have 4 years experience in Java programming. But I think there are a few good books for SCJD.
Look at Javaranch.com, there is a list with books for exam.

I started programming with the server IO part. Try writing test cases for this part. Then I implemeneted the networking part and after that changed to the GUI.

I tried to keep things simple.
- No table sorting (try to use JDK 1.6, but failed exam - got a free resubmission)
- No AND/OR search options in GUI, just 2 textfields
- Hardcoded Strings for dialogs and so on
- syncronized CRUD(create,read, update, delete) methods - yes I know only one thread could write to file, but I mentioned it in choices.txt

For locking I made a class that represents the lock of one record. In my Data class I have a Hashtable<Long, RecordLock> that holds the objects.
You must think about which methods have to be syncronized !!! (so that never ever 2 threads could hold the lock on the same record)

FOr mor info contact me via email or pm
