Today I got the certification J6 OCJP IZO-851.
I passed it with 65% but it's a pass.
I did the tests from Ets(first) and Whizlab(second) and then Whizlab again and Ets again, reviewing all questions, mostly questions that were answered wrong.
It wasn't a surprise the result of 65% because in the exam tests I've been passing them with maximum 74% but I passed all of them. I didn't want to invest too much time in the exam. I took me about 5 months to study also working in this time.
About questions in the exam:
- no drag and drop questions
- no serializable questions
- a lot of questions with interface, class implements interface, casting, interface extends interface, class that implements 2 interfaces and extend another class that also had an interface.
- maximum 5 question from collection (TreeSet, Comparator Comparable -what method to implement compareTo or compare)and 4-5 from generics.
-
Thread questions 4-5 - not so fifficult as the once from Whizlab and Ets.
- 1,3 questions with enums, type was passing throug a switch as I remember
- with anonymous class
- 3-4 encapsulation and cuppling and choesion
- overriding
- also question with... accessing modifiers like protected and private, accessing variables, overriding methods with protected over default etc.
- arrays
- questions with compiling and running javac a
java with classpath etc. study them good before going to exam!!!
- files question ... not so difficult ... about 3 questions, like rename a dir and create some file.
- inner classes 1 or 2 or... i don't remember much...
- 1, 2 garbage collection with finalize and... something like this.
From what I've seen about the questions... as a remark ... the lines of code were not so many in the questions. The code was simple and straight. Like they are seeking what it is to be tested and put it in some small code and this code is sometimes tricky.
The Ets questions are more complex by the fact that they have a higher a number of lines in code but helps you on solving fast the simple code of exams.
and... now... that's all I remember.... shortly.
