Cool! I have studied pretty intensively for a month, using my old copy of Bill Brogden's book (pretty complete, well-organized), JQPlus (excellent! the robust features were well worth my $20, and many questions closely resembled those I saw on the real
test), and Marcus Green's mock tests. My recommendations to studyers/test-takers: Know Threads inside out, know the I/O API including the constructors (mainly know the particularities of I/O class categories & how their constructors reflect that), practice as many good mock tests as you can, and check the more complete advice and notes you can find throughout Javaranch.
Many, many thanks to all who have contributed to Javaranch over the last coupla years. I started coming here in 2000, mostly to play the Roundup game. Put off taking the
SCJP test until now as it wasn't important to me -- I have been a professional programmer since 1997, using
Java since 1999, and until being laid off recently have had no problem getting better jobs as my programming experience has grown. Anyway, maybe SCJP will help me professionally going forward! and studying for it has improved my Javaknowledge, some trivial and some deeper.
