Sorry to hear that you failed to pass the exam. It is a tough exam, so, don't lose heart. You will surely pass next time.
Thanks a lot for your feedback on the exam. A few other people also reported getting questions on FileChannel and setNull. Although FileChannel may be out of scope (and it might be an unscored question), the setNull method of PreparedStatement is squarely within scope.
We tweeted about it as well as updated our question bank last week to include questions on these topics.
Hi, I took the exam 1Z0-819-J recently and I can confirm that both concepts were in the exam. I meant to share this but forgot.
So I don't know about FileChannel (I hate IO stuff and cannot force it in my head so I just ignored it).
But this setNull was something I stumbled upon and was not prepared for (I have the Selikoff/Boyarsky book). So yeah, watch for it. I prepared for the upgrade exam, but since the J exam is cheaper decided to give it a go.
I passed but nothing to write home about Hope you will have more luck next time!
I ran out of time, so I just guessed two or three questions...
I found the questions in the Study Guide more difficult than the questions on the exam. The exam has less answers options (mostly four or five options). Furthermore the exam uses the does-not-compile-option less. So you have to spend less time searching for compilation errors. On the other hand the exam had less code-less questions. Almost every question contained a piece of code you have to interpret. All things considered my failed exam score was the highest I got so far. 😊
