I am about to take the Java 6 SE Certification Exam on Thursday. Just wondering if any of you found anything unexpected on these exams or things you wished you had paid more attention on.

Any general tips, tricks, or warnings, would be greatly appreciated.

(Please don't waste time trying to tell me that I am wasting my time/money, because I am just doing this so that I can get an instant A in my Java class.)

The c# question at the end threw me. But I caught it and handled it ok. –  Kevin D May 2 '11 at 17:42
Just because of the certification you get an INSTANT A? I would say you are wasting something... –  Tom May 2 '11 at 17:43
@KevinD ...am I missing something or was that a joke? –  ioSamurai May 2 '11 at 18:46
@Ryan I think its an exception joke but I'm not sure –  alternative May 2 '11 at 19:59
@Ryan it was. Not saying it was a good one, but it qualifies as one. :) –  Kevin D May 3 '11 at 7:54

Nothing really hard in the JCP if you:

  • know the basics of the language well (keywords, syntax, semantics...),
  • have a good general overview of the class lib's package tree,
  • know the most used collections and the java.util.* package relatively well,
  • have some understanding of multi-threading (always a few questions about that; be sure to know how to use Thread and Runnable correctly),
  • have coded a fair amount of code.

You need to be able to read code and be confident in your answers to not keep thinking "no, that can't be that easy...", because most of the time it actually is.

Good luck.
