Hi just thought I'd start a general comments thread. I just wanted to say that when I first looked at the specification I didn't have a clue how to do it and now that I see what it is all about it is making more and more sense to me.

Hi Mandy,

I also intend to take the SCJD exam, and while I'm still on my way of saving some bucks for the voucher, I decided to have a "feel" of what the exam has got for the takers. Im reading, and sometimes post question regarding it and everything looks fuzzy right now but I know that when I get to have my hands on the assignment, everything will gradually be clear.

Goodluck to us!

Yes Mandy, I am just starting out with my assignment and I am trying to figure out my input file. Things are getting clearer slowly, but I am banging my head on why the input file is so complicated.



Good Luck!

I have been working on this for over a year now, and it has gotten much clearer. I suggest taking a look at these threads: http://www.coderanch.com/t/185360/java-developer-SCJD/certification/Reading-db
http://www.coderanch.com/t/186239/java-developer-SCJD/certification/Reading-binary-db-file and getting a hex editor in order to deal with that file. I have that part done, but I'm a little stuck trying to incorporate it into the actual program, actually separating out individual records. But I'm sure I'm near a breakthrough! Actually, I totally wrote the file reader just from those two threads, so it's all there.

The first thing I did was write a data file parser. I read the various fields in, made a schema object, and then dumped the read fields to STDOUT. Once I was getting meaningful data values there, I knew that I was interpreting the file correctly.

Honestly, the file format is easy - it's a flat file; no indexes or anything nasty like that, and once you've worked out how to read data from it you're more than 50% of the way there.

Thanks All!

I have been able to get the schema traslated and input into my program as ContractorRecords, with record numbers. I am working on getting my Data class to implement the interface methods.

All thanks to previous posts. This forum is awesome. I have literally spent 30 hours reading posts all the way back 5 years. I am so impressed with the help and community support. And I bought Andrew and Terry's book. To see Andrew posting with help really encourages me.

I still am going to have more questions, but I am moving forward.
