Hello all.

This is first ever post on coderanch. Before I start, let me say thanks to all on this forum as I have got great help so far. But I am confused a little.


I bought Enthuware mocks for IZ0-813. I have read Oracle Certified Professional Java Se 8 Programmer II Study Guide. It has great division and mentions what I need to study for IZ0-813 upgrade exam.


But but but....

I am getting questions in mock tests for like TemporalAdjuster for Date Time API. I can see see questions for ThreadLocalRandom. Same for questions around File Meta Data Attributes such as about PosixFileAttributes. I can see questions around those methods of AtomicInteger (such as addAndGet) which book excluded intentionally and said you only need these to remember. I got questions around Map.forEach that book never discusses at all. I can't even find these topics in book.



So. Anyone who has done the exam. Can you please tell me  - Can I assume that this is problem with Mock questions going beyond what is needed OR it is actually a case in real exam. For example Oracle says in exam topics "Use classes from the java.util.concurrent package ". How can I find what exactly is involved? Is there any comprehensive list of underline topics that I am missing?? How does this book knows that we only need these methods from AtomicInteger class??



I have booked the exam for next weekend so I am confused if I need to read about all what I find in mocks can be very stressing.

Please help.

Thanks
Ilyas

Hello M Ilyas!

Few month ago I take the upgrade from Java 6 to Java 8 and bought the mocks for enthuware and certainly can said that you need to study several topics found in the Java 7 certification and the mock have include that kind of question.

I studied with the book Oracle Certified Professional Java Se 8 Programmer II Study Guide and this have a complete chapter that talk about the additional objectives for take the upgrade.

So Yes, you need to study this additional topics for can answer question about java 7 technologies (even though some of them are obsolete in java 8)

Greetings
