Did you have any Advance java knowledge or experience before ? how many weeks it would take for one to clear OCPJP ,if one has no prior java hands-on experience but has cleared OCAJP ?



Hi Vidya,

If you don't have any previous hands-on experience in Java development, I think it is feasible if you go full-time 6 weeks straight on preparing for the exam.
About 50-60% of questions are on generics, collections, and functional programming. Therefore, if you want to pass the exam, you must know these topics inside out.

Cheers,

Igor

Thank you, Jeanne. Yes, this exam is way tougher than Sun's SCJP 6 which I passed in 2009.

I would like to thank you and Scott for your straight to the point study guide.

Cheers,

Hello, fellow ranchers!

I'm happy to inform you that I passed my Java SE 8 Programmer II exam with 80% after five weeks of intensive preparations.

Here is what I did to prepare for the exam:
1. OCP Java 8 Study Guide by Jeanne Boyarsky and Scott Selikoff: read twice, did all review questions
2. Enthuware mock exams:
Test 1: 66% - passed
Test 2: 59% - failed
Test 3: 62% - failed
Test 4: 61% - failed
Test 5: 62% - failed
Last day test - didn't have time to do
3. Created flashcards on Quizlet.

Cheers,

Igor

Hello Will,

Here are the highlights:
1. 126 questions/3 hours
2. I completed about 110 questions, my compiler was kinda slow that day
3. Most of the questions are "be-the-compiler" questions on lambdas and streams
4. You'd better to know by heart the main built-in lambda types and Streams APIs, and some practice wouldn't hurt either
5. Streams.peek() is not on the topics list but I had a few questions on it.

A small number of stream operations, such as forEach() and peek(), can operate only via side-effects; these should be used with care.


See for more details: http://docs.oracle.com/javase/8/docs/api/java/util/stream/package-summary.html

Cheers,

Exactly, that's against the Oracle's policy. I suggest you look into the examples I implemented while preparing for the exam - it should give an idea what to expect.

RE: How deep knowledge of javascript in Nashorn question are required?

Basic knowledge of Javascript will suffice.

Hello,

I took the Java 8 OCA beta exam in November last year and recently received a confirmation that I passed it with a score of 75%.

Also, I took the Java 8 Upgrade beta exam today. Since the beta period ends on the 18th of April, I wll get results not earlier than the mid of June
My primary preparation source for the exam was the Java 8 in Action book.
I also compiled/implemented some kind of resources reference with examples for the exam topics.

Cheers,

Igor

Hi Gurpeet,

RE: can you please tell me that do we have to study everything from servlet 3.0 specification or there are some specific sections/topics.
Pay special attention to asynchronous processing, annotations and pluggability but it wouldn't hurt to read the whole specification either.

RE: also can you tell me the difficulty level of exam in comparison to enthuware mock tests ?
The actual exam is easier than the Enthuware's mock exam.

Cheers, Igor.

Hi ranchers,

I am happy to share with you that yesterday I passed my OCPWCD Java EE 6 exam with a score of 87%.

Here is what I used to prepare for the exam:
1. HFS Servlet & JSP, 2nd edition
2. Mikalai Zaikin's study guide
3. Servlet 3.0 specification
4. Enthuware's mock exam – did all main exams with an average of 72%

Cheers, Igor.

Hi Prasath,

You can use EJB3 to implement the business(or services) layer in you web application.
I do not know what kind of your web app is but using EJBs might be overkill.
You can dispense with EJBs and use POJOs with Spring lightweight container instead.
If you go without EJBs, I would suggest that you read "Expert One-on-One J2EE Development without EJB" by Rod Johnson.

Regards,
Igor Baiborodine.
Hi ranchers,

Just passed exam with 86%. Here is my by section break down:

The Servlet Technology Model..........................................83%
The Structure and Deployment of Web Application..............75%
The Web Container Model.................................................71%
Session Management......................................................100%
Web Application Security.................................................100%
The JavaServer Pages(JPS) Technology Model....................85%
Building JSP Pages Using the Expression Language(EL)........80%
Building JSP Pages Using Standard Actions.......................100%
Building JSP Pages Using Tag Libraries...............................87%
Building a Custom Tag Library...........................................80%
J2EE Patterns.................................................................100% (D'oh! No beer from Mark Peabody)

Here is my road map to success:

1. HFSJ - read twice
2. Enthuware - JWebPlus5(did 7 tests with 72% average)
3. Revision notes by Frederic Esnault
4. Design patterns notes by Mark Peabody

I want to thank Bryan Basham, Kathy Sierra & Bert Bates for their brain-friendly study guide,
creators of JWebPlus5, Frederic Esnault and Mark Peabody for revision notes, and all ranchers
for your support.

Yes, it finally happened after four months of vigorous preparation. I have got 75%. Here is my by section break down:

Declarations, Initialization and Scoping…83%
Flow Control…100%
API Contents…80%
Concurrency…50%
OO Concepts…60%
Collections/Generics…60%
Fundamentals…81%

Threading was my real Achilles’ heel. I could have done better overall but got too nervous and just could not think straight at the beginning of the exam. Also was stunned (yes, stunned) by the simplicity of the exam questions. Sometimes I was just spending too much time on plain simple questions trying to find the catch. But I am happy what I have got.

Here is my preparation path:
1. HF Java by Sierra&Bates – read once
2. SCJP5 Study Guide by Sierra&Bates – read twice
3. Whizlabs SCPJ6 Preparation Kit – did all exams with an average 70%.

I find that the study guide by Sierra&Bates is the best book on the market. Whizlabs’ kit is good enough but it suddenly died two days before the exam. For anyone who wants to pass the exam in Montreal(Canada) I would recommend Expertech testing center: quiet, comfortable chairs, air-conditioned, convenient downtown location.

Special thanks to Kathy Sierra and Bert Bates for their amazing books and all ranchers for your help.

Hi Ruben,

but don't forget that int[] CANNOT be boxed into Integer[] and vice versa.
Hi guys,

I think it is more simple if you put it that way:
1. Is int[] instance of Object class? Yes.
2. Is int[] instance of Integer class? No.
That is way the second line does not compile.
Hi,

I think it is because an instance of Iterator provided by Collection.iterator() is used in for loop. In Collection.iterator() API you can read following
"Returns an iterator over the elements in this collection. There are no guarantees concerning the order in which the elements are returned (unless this collection is an instance of some class that provides a guarantee). "
