Hi,

Web site looks different than the last I visited, so I hope this is in the right place. My question is pretty much summed up in the subject, I attained the OCA 7 in 2015 and want to know if I can go straight for the OCP 8 now, or do I have to do the OCP 7 and then do the Java 8 upgrade exam?

Thanks

The greet variable in method niceMethod(String greet) in class WTF is just a local variable to this method and without using the "this" keyword it just reassign the value to itself instead of assigning the instance variable greet.

The niceMethod(String greet) in class WTF2 assign the value to the instance variable greet because of this.greet while the nicemethod2(String greet) is doing the same thing as nicemethod(String greet) in class WTF.

Now, when we print value of wtf.greet:

1. In class WTF, wtf.greet is set by nicemethod2(String greet) and before its only using its first initialized value "String greet = "Hey Willem";"
2. In class WTF2, wtf.greet is set by nicemethod(String greet) and nicemethod2(String greet) will not change the value of wtf.greet so whenever you print wtf.greet it will show the value set by nicemethod.



After re reading this a couple of times it makes better sense now, thanks

So in the niceMethod method of the WTF class you usewhich simply assigns the method parameter to the method parameter (and not to the instance variable).l



Mmmm if I just had to read the code for the 1st time that would'e been my exact thought as well, BUT then how come when niceMethod in WTF class gets invoked and passed the String "Hey Dude" it still prints the value of the instance variable "Hey Willem"...
Can't wrap my head around this one, someone please explain, almost 2 identical classes, only difference is, the call to this is in different methods

Class 1 gives output of:
Hey Willem
Hey Dude



Class 2 gives output of:
Hey Dude
Hey Dude

For other aspirants it might be helpful if you could elaborate on how you have studied/prepared yourself during these 10 days. Did you just read/study the K&B7 study guide? Did you create lots of code snippets? When coding did you use an IDE or a text editor? ...



Read through K&B7 book, worked through 6 Enthuware mock exams (but I only found out in this thread the ebook i bought back in 2013 might actually contain mistakes)... I did write lots of code, looking back now there's at least 50-60 classes in my "Java 7 Prep" project in Netbeans... There's none of the topics I don't understand to be honest, quite frustrating, not to sure how to go about my preparation for the test again next month

The only one thing I didn't do in my preparation was to time myself, I took my sweet time with the mock exams, and this got me into the habit of taking things slowly, which is a very bad thing I suppose

Based on this important note from OCAJP Oracle Certified Associate Java SE 7 Programmer Practice Exams on Amazon, I would say yes.

Mmmmm but it also mentions "updated automatically on a regular basis." Waiting for Paul's reply on this, maybe worth getting this is there has been some changes


Willem,
In case of the simulator, we control the update process and so a user gets the updated version as soon as we update it. We do update the eBook on Amazon also at the same time. However, we do not know when the customer of the eBook gets the update because it is done by Amazon. Therefore, an ebook user may see errors that have already been fixed. For this reason, we have included the statement that you've quoted.
If you have purchased the ebook, you will not get anything new, in terms of content, by purchasing the simulator.
HTH,
Paul.



I bought the ebook in 2013.... I see on the website the simulator has 7 tests, the ebook only has 6


We did quite a bit of reorganization as well as add new questions a few months ago when Oracle made changes to the exam (they changed the number of questions, duration, and pass percent). The current version of ebook on Amazon reflects the same.
But it looks like Amazon has stopped updating yours. We are not really sure about their policy on for how long and how frequently they update the readers. In this case, you will see about 20% change between the old and the new version.



In that case I'd say its worth buying, tested the trial version of the simulator now, a lot more organized, and keeps better track of what you need to improve on etc... Thanks for your input

Just some feedback from my side, i just failed the test by 3%... FOR THE 2nd time, FML!

I first wrote the exam in 2013, back then the passing score was 77% if I remember correctly, I went into the exam not really knowing much, and kind of "winged" it and managed to walk out with 73%, still failing none the less... Fast forward to the present and I managed to land a junior developer job thanks to an IT diploma I have, and I've been coding full time in JavaScript for about 18 months(Obviously the exam doesn't cover scripting language, but it helps to work in a coding environment on a daily basis).. I thought I'd give this test a go again to spice up my CV, read around on the forums and heard that the difficulty of the test is still the same, and the pass rate is now lowered... I Thought "great" should be "easier" this time round, I put aside a week and a half of full time studying (about 6-8hours a day), worked through the new OCAOCP 7 textbook by Kathy Sierra and Bert Bates, and also through all the mock exams in Enthuware, my scores were as follow:

Test 1: 48% ( I was rusty here, did this test prior to consulting any study material)
Test 2: 58%
Test 3: 61%
Test 4: 68%
Test 5: 71%
Test 6: 77%

As you can see I really improved in as little as week, and after reading that the actual exam is easier than these tests I thought I was ready.

So the first time around in 2013 I finished with like 30mins left, I knew the time of this exam was also reduced from 2-1/2 hours to only 2 hours, but seeing that I didn't struggle the first time, concern didn't even enter my mind.

Well I would say the actual exam was on par with most of the Enthuware as far as difficulty goes, but compared to the first time around this felt much harder, there were A LOT of questions with bloated code snippets that is just very hard to work through given that you only have about 90 seconds per question, I would say the first time I took this test for every 3 straight forward questions there was 1 question the needed some thinking and working through... This time it felt the other way around... And this totally caught me off guard, about 60mins into the exam, I realized I was only 33 questions in, with a few marked for review already, and that's when I started to panic, and just pushed to get through the questions, I'm fairly certain I would've easily made it if I had more time, but you know what they say about "IF's, but's and maybe's".

Anyway thats just feedback from my side, so that future exam candidates reading this can use this knowledge so they're prepared for the time limits

I'm rescheduling this for 2 week from now, this time I wont be caught off guard again.

Any idea where I can get different mock exams, don't want to work through the same ones again.
Hey

Is it just me or was the past rate lowered for this certification in 2014, I remember writing this last year and the pass rate being 77%, according to this link its 63% now http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=652&get_params=p_exam_id:1Z0-803 is this correct?

Hi Bruyn, How is the exam?

Let us know your experience



Man not so good, just fell short of a passing mark, got 73%, but I rushed my preparation a bit, back to the drawing board i guess, will take the test again in another month or 2
Okay so I just took the exam for the fist time, feeling somewhat negative at the moment, got 73%... but I'm not the type to quit this easily. Where to next?

I used this book http://www.amazon.com/OCA-Java-Programmer-Certification-Guide/dp/1617291048

And did mock exams from here http://www.amazon.com/Certified-Associate-Programmer-Practice-ebook/dp/B007SA1GNU

But I don't feel like going through the same stuff again, can anyone recommend something new, I see a lot of people recommending this http://www.epractizelabs.com/certification/sun/javase7oca.html is it worth it? Or pretty much more of the same as the exam prep I already have, should I just suck it up and start from the beginning again :P

Hey, so here's the piece of code, with the output below.

OUTPUT:
20
10
11
10


I can't wrap my head around it, I can see why the 20 and the 11 should print, but why the 10 gets printed twice I don't get.
