I had seen this article – “5 Free OCAJP8, OCPJP8 Mock Exams and Practice questions – 1Z0-808 809 (Java 8 Certification)” – and had looked at some mock exams. I see some ranchers frequently ask about certification mock exam so I decide to share it
Whizlabs questions were very simple. My result was 20/20 so I didn’t look at any question again.
After whizlabs I didn’t take seriously it and I did this sample test in my mobile phone with walking. But my result was surprised me (17/25) therefore I began to look through questions..
The answers of questions 16, 18, 21 and 22 were wrong. Question 19 and 20 were duplicate. Question 7 was required three correct answers but there were only two correct answers.
I didn’t look at explanations in detail but I saw some typos in there.
There were some interesting questions but there also were wrong explanations so I suspect the quality of the test.
For example, there were a lot of typos in the following explanation:
Stings are mutable objects, simply it means once we invoke method on string and apply some changes new string return instead doing change itself. But Stringbuilders are not mutable.
So at line 7 invoking contact method won’t do any change on the str object instead it returns new string “1Z0-808”. So finally 1Z0 will be printed. Hence option A is correct.
The LocalTime is an interface, so we can’t use new keyword with them. So options A and B are incorrect.
The Instant is an interface, we can call its now method to get current date and time, so option C is correct and option D is incorrect.
Maybe the answer of two questions (first about lambda-Runnable, the other about GC) were wrong.
