I want to thank You all for help. Special thanks for:
Katherine Sierra & Bert Bates (for awesome book for SCJP),
Henry Wong (great, great knowledge and experience),
Cameron Wallace McKenzie (your anthropomorphization is great),
Devaka Cooray (your ExamLab is the best simulator ever).
More people like You and the world become better.
Moreover the climate here, on JavaRanch is very, very friendly - I can not say the same about forums in my country.
I cleared SCJP6 with a very good score last week and it would not be possible without Your help.
Thanks You all again.
I think that I will stay on SCJP forum and I will try to help other Java Ranchers, if I have enough knowledge, of course
