2 Weeks ago, just before the start of my holidays, I got the message from Oracle that I successfully passed my Oracle Certified Master, Java SE6 Developer certification.
I have not been posting here before, as I was able to find answers to all my questions in the rich archive of this forum.
These forum threads have been of great help to guide me in the right direction.
Thanks a lot to all, especially to Roel De Nijs and Roberto Perillo for all the helpful answers!
And good luck to all working on their assignment.
