This site covers study material for Sun's Java 2 Programmer Certification (SCJP2) and Sun certification for web component development (SCWCD) exams. Refer to Sun's site for more details on the other exams.

What are the prerequisites for taking the SCJP exam?

There are no prerequisites for SCJP. You do not need to clear the Java Associate exam, before taking the SCJP.

How much time do I need to prepare for the Java Programmer (SCJP) Certification?

The time you need to spend on preparation depends on your background and experience in programming languages in general and Java technology in particular. Assuming you have good background in object-oriented languages like C++ or Smalltalk, but do not have much experience in Java technology, it may take you one to two months to prepare for Java Certification. If you have some experience in Java technology, you may need to spend two weeks to a month to prepare for the Certification exam. The Certification exam covers some of the details of the Java technology that may not be commonly used by a Java programmer.

In case you do not have any background in Object Oriented Programming but have good experience in Procedural languages like C or Pascal, you would need to learn Object Oriented fundamentals also. Sun's Java Certification exam is hard. There are a large number of good books on Java Certification and tons of information available on the Internet to prepare for the Sun Certification. These resources have made the Certification achievable (if not simple) for most people with good aptitude in programming.

Which books are available for Java Certification?

Please refer to the books section of this site. My personal favorite is the Khalid Mughal book.

What is the difference between SCJP 5 and SCJP 6 exam.

Sun is offering two exams at the programmer level - SCJP 5 and SCJP 6 . The exam number for SCJP 5 exam is CX-310-055. The exam number for SCJP 6 exam is CX-310-065. Content-wise the major difference between the two exams is that SCJP 6 includes a few additional classes -, java.util.NavigableSet, java.util.NavigableMap . The level of complexity of both exam is same.

Number of questions 72 60
Correct answers required 43 35
Total time 175 minutes 180 minutes

Should I take the SCJP 5 or the SCJP 6 exam?

SCJP 6 tests the latest version of Java programming language. So it makes sense to go for the latest (SCJP 6) exam.

I have SCJP 1.2 (or 1.4 or 1.5) certification. Should I upgrade to SCJP 6?

Sun offers an upgrade exam to SCJP 6. The fees for this is $300. In my opinion this has only limited value. Your SCJP 1.2/1.4 certificate is still valid. Your time is better spent on taking other certification exams, rather than upgrading to SCJP 6 certificate.

How many questions are there in the SCJP 6 exam.

The Sun's Java Certification Programmer 6 exam consists of 72 questions. These need to be completed in 210 minutes. To clear the certification exam you need to get 47 correct answers.

There are three type of questions in the exam -

  1. Multiple choice questions in which you have to select one or more correct answers from a set of options. A majority of the questions are of this type. In the exam it would be clear from the question whether it has one correct answer or multiple correct answers. For questions with multiple correct answers, you must get all the correct answers, to get credit for that question. Also these type of questions will mention the number of correct answers.
  2. True or False type questions
  3. Questions that require you to drag and drop items from one column to another.

How does Certification help my career? Would it help in my job search? Would it give me a better salary?

If you are looking for a job in Java technology, then the Sun's Java Certification adds a lot of value to your resume. Specifically if you do not have any industry experience in Java technology, and you are looking for a job in Java, the certification will increase your chances many-fold. It is hard to put dollar value on the Certification results, but on an average certified programmers get higher salary than non-certified programmers, everything else being the same. If you have many years experience in Java programming, than the SCJP certification may not add a lot of value to your profile.
