Anybody who took an exam could comment on an depth of knowledge needed for an Exam?
Thanks,
Alex
Well, I am in Houston and also working of my SCJD assignment. I know that there is a generic Java study group, but have not heard anything about SCJD group. What do you have in mind?

Hi Matt.
Look at getColumnClass method of the AbstractTableModel. Based on the return type - JTable will choose the appropriate renderer. Or a more long winded approach, try to register your own column renderer, look at getTableCellRendererComponent method of TableCellRenderer. Plus, I have seen recommendation to look at Sun's Look and Feel specs and see whether the data type you are trying to center align should be there or maybe left-justified.

The first step I considered and implemented is to compile what has been given and run the most simple test against the binary DB file. As a file is already in binary format, I think we just might let it be. But the small test will at least let me see what's inside this file. I also started to put a prototype for GUI as right now it is mostly following Sun's look and feel design guidelines.
I wonder how many people choose RMI over serialization/sockets?
I think you will do well. Mock exam can be a study material in itself. I found them as helpful as any certification books. Plus, as you may knw already that the time has been changed from 1.5 hours to 2 hours, which give one a piece of mind.

It's hard to follow the post from one of the book authors, but I will give my "practical" opinion. I passed the test last night. Score is not in the nineties, but the job is done. What worried me when I was prepearing are those tough questions, that were posted from different sources and Khalid etc.. book as well. It's a good source of Java trivia but if your goal is to get certified, and believe me once you get it you will feel that you worked for that, then it's something you can do without. Real test did not have any of those mind numbing questions. I used RHE, Cram and mock tests.
I took the test a few hours back (found a place that offers seating for exam till 8 PM). Firstly, the customery thanks goes to the this site keepers and to the people who created mock exams. Now, about exam before I start paging out info from memory.
Infamous Mr. Green's tests are close to the real test, but I have to say that the test is harder.
I have not seen anybody mention that but I got 3-4 questions worded "choose the best answer". First one after a looking for a few seconds becomes clear, just go over Math.* functions and see the signatures. One I had to guess and probably missed - not to be in my shows, please go over io classes constructors. One was just plainly unclear as 4 options seemed correct and choosing the best was very unobjective.
There was only a couple "here comes Christmas" questions that looked like presents and it takes only a second or so to see the answer.
There was a couple questions made specifically for ex-C++ developers to throw off their game, by using familiar from previous life notations.
Threads had around 7 questions. Nothing major, now how to create/start a new thread: Thread::start schedules a thread and run method will be executed. Get a basic understanding of synchronized and keep in mind that if the block of code is not protected - a running thread can be preempted at any time.
KNOW YOUR BASICS. Man, do they test you on the basics. I saw everything: primitive ranges, loops, BTW look at nested loops with labels and continur/break. Get a solid feel for overload/override. Remeber the access modifiers order: public-protected-default-private.
Some questions from exam were very closely matched with questions from mocks - my theory is that if one just studies all the mocks and works on missed questions, then you can do real well on exam.
You will have plent of time - 120 min. to go over all the question with no rush. I decided to do just one sweep and took as much time on one question as needed to make a decision and still had half an hour left.
GOOD LUCK
