I was just taking one of the practice tests for Wizlabs SCJP 6.0 and there were 3 questions relating to classes ConcurrentHashMap, ConcurrentSkipListMap, and ConcurrentSkipListSet.

I don't remember seeing anything about those classes in the K&B 6 book at all, and going back through the book I can't find any mention of them either.

Are these classes required knowledge for the real exam? Is there a reason they are not in the book?

Thanks!!

Brian if it's not in K&B, it is not likely to come in the real exam...

That is what I was thinking Ankit and the reason I am posting it here. I am using the newest version of Wizlabs SCJP 6.0 and it had 3 questions relating to the above mentioned classes. That is 4.2% of your grade. Sure, it's not a significant amount but if your right on the border of pass/fail then it IS a big deal.

Would like to know if anyone has taken the real deal and seen ANY questions related to any concurrent collections?

Thanks!

I dont think you get them as they are not mentioned even in scjp 6 objectives.

I didn't think any actual classes were mentioned in the objectives are they, just concepts?

I know that Ritu Sharma frequents this site, so he may have some more insight on this.
