Hi from France,
I passed programmer certification java 1.4 on 20 september.
Just a few notes:
a) Dan & Marcus tutorials are a great help (specially dan exam for collections)
b) It looks normal that the "Java Language Specification" book must be read to avoid casi all tricks. But hard to read for non american
c) I had casi no questions about assertions
d) I think it's quite easy to fail this exam if you're not concentrated or have only an average practice of Java
In the result statistics, Sun should indicate the number of questions per objectives.
This site is very good. Thanks to you to the help you provide through your links, exams, and cow test.
meuh and sorry for bad english
