Hello,

I got my OCPJP certification last fall and now I plan to expand my knowledge in relation to the Java platform. My initial thought was to go for Oracle Certified Master for Java Developer (formerly SCJD). As far as I saw on the Oracle's site, this type of certification is prohibitively expansive because of the compulsory training that you have to attend to, which costs around $2000.

As far as I looked on the Oracle Certifications Site there are some certifications that don't require a compulsory expensive training and those are: Oracle Certified Expert Java EE 6 Web Services Developer, Oracle Certified Expert Java EE 6 Web Component Developer and there may be others.

What I am asking are the following:
1. Is Oracle Certified Master better for employment purposes than Oracle Certified Expert?
2. Given that I have the Programmer certification, what certification level do you recommend aiming for? OCE or OCM?

Thank you.
Yes, I've run it and encountered deadlock several times.

When I say that the main thread acquires a lock, I refer to the point when the hunter method is called from the main thread.

Correct me if I'm wrong, but as far as I understand this, the lock for the thread referenced by 'q' may be taken by either thread 'q' itself when running run() method or the main thread when calling hunter() method.
Hi,

I've encountered a question on certpal.com site at the exam from all topics no. 3 for Java 6. The question number is 34.
Here's the code snippet:



They say that the correct answer is the first one: the fact that the output is guarenteed to be 4444.

But, when running the above code it seems like deadlock is an usual issue. In my opinion, this happens because the Main thread acquires a lock for one of the 4 objects(let's say A) and then the A thread can't call its run() method since the lock is taken away by Main.

I'd rather go for "The ouput is not guarenteed".

What do you think?
Hello everyone,

My name is Ariel and I've recently finished the K&B (Java SE 6) book. I've came across a book called "OCP Java SE 6 Programmer Practice Exams" by the same authors.

That book was published in November 2010 and at that time Oracle was acquired Sun, as far as I know. The details about the exam that the above book gives are the old ones about SCJP such as:
- the exam code
- the 180 minutes you have at your disposal
- drag and drop questions

My questions are:
1. Is this book good for taking mock exams in terms of the OCJP exam?
2. Are drag&drop questions still present in the latest version because I read a lot of contradictory information in books and Java Ranch forums.
3. If the answer to 1. is yes, are the OCP Practice Exams and SCJP preparation CD(MasterExam attached to K&B Java 6) enough for taking mock exams?

Thank you very much and sorry if the questions that I raised were answered before.
