Top 5 myths and misconceptions on taking ocpjp 7 exam

  1. 1. Top 5 myths and misconceptions about the OCPJP 7 examMyth #5: If I pass OCAJP 7 exam, Ill pass OCPJP 7 exam with ease -both are similar except for top-level exam topics!   No, no, no. OCAJP 7 and OCPJP 7 are different beasts. OCAJP 7 is much easier thanOCPJP 7 exam. Oracle wanted a large base to start with, and hence OCAJP covers onlylanguage fundamentals; just take a look at the OCAJP 7 exam topics to understand what wemean. However, OCPJP 7 is a more difficult exam which covers a wide range of examtopics (JDBC, Concurrency APIs, localization, design patterns, ...) as well as topics in depth(just take a look at generics and collections topic, for example). Yes, some questions in OCAJP 7 could be as difficult as OCPJP 7 exam, but in general,OCPJP 7 requires much more preparation. Overall, it would be a very bad idea to appear forOCPJP 7 exam without any preparation, but it may be okay for OCAJP 7 if youveconsiderable programming experience in Java.  Bottom-line: Don’t measure both the exams with the same scale. If youve passed OCAJP 7exam, dont look at OCPJP 7 exam as something similar - they are very different at theirdifficulty level. So, prepare more for OCPJP 7 exam even if youve cracked OCAJP 7 withease. Myth #4: I have many years of work experience in Java, so I donthave to prepare for the exam. No matter how much real-world programming experience you might have, there are tworeasons why you should prepare for this exam to improve your chances of passing it:  • You may not have been exposed to certain topics on the exam. Java is vast, and you might not have had occasion to work on every topic covered in the exam. For example, you may not be familiar with localization if you have never dealt the locale aspects of the applications you were engaged with. Or your work might not have required you to use JDBC. Or you’ve always worked on single-threaded programs, so multithreaded programming might be new to you. Moreover, OCPJP 7 emphasizes Java 7, and you might not have been exposed yet to such Java 7 topics as NIO.2, new concurrency APIs, and enhancements such as try-with-resource statements.  • You may not remember the unusual aspects or corner cases. No matter how experienced you are, there is always an element of surprise involved when you program. The OCPJP 7 exam tests not just your knowledge and skills in respect of regular features, but also your understanding of unusual aspects or corner cases, such as the behavior of multithreaded code and the use of generics when both overloading
  2. 2. and overriding are involved. So you have to bone up on pathological cases that you rarely encounter in your work.Bottom-line: Work experience in Java is good, but youll still need to prepare. A groundedand practical approach would be to take mock-exams in our book - if you pass the mockexams, youre likely to pass the real exam - at least this approach will save you $300! Myth #3: OCPJP 7 exam questions will be equally distributed amongthe exam topics.  If you look at the list of exam topics for OCPJP 7 exam (see this link), youll find 12 top-level exam topics. Somehow, there is a misconception that youll get 7 to 8 questions (i.e.,90 questions / 12 exam topics = 7.5 questions) per exam topic. However, based onexperiences in taking exam, this is not true. Specifically:  • Youre sure to get questions on fundamentals, i.e., questions from OCAJP 7 exam topics, so, this distribution doesnt hold. • You may get more questions on a specific topic (such as generics and collections) when compared to other topics. • You may not even get any questions on a topic. For example, many takers of exam have reported that they did not get any questions in topics such as Concurrency or JDBC.  Bottom-line: Prepare well for all the exam topics and dont be surprised if you get a largenumber of questions from one exam topic and very few (or even no) questions on someexam topics. Myth #2: OCPJP 7 exam questions will be exactly from the examtopics.  Yes, Oracle has listed exam topics (both topics and sub-topics) for the OCPJP 7 exam (seethis link). The questions from the exam will be mainly from these high-level exam topics.However, exam questions are not constrained to be exclusively from the topics on the examsyllabus:• You might, for example, get questions on Java fundamentals (a topic in OCAJP syllabus) concerning the basics of exception handling and using wrapper types. Or consider the exam topic "Test equality between Strings and other objects using == and equals ()" listed under "Using operators and decision constructs" in OCPJP 7 exam - you may get questions on this exam topic. • You might also get questions on topics related to those on the exam syllabus but not specified in it. For example, serialization and use of the transient keyword are not explicitly mentioned in the OCPJP exam syllabus, but they can come up in the actual exam because they are related to reading and writing streams—and one of these is ObjectStreams, which relates to serialization!
  3. 3. • Consider this exam topic "Format strings using the formatting parameters: %b, %c, %d, %f, and %s in format strings." under "String processing" in OCPJP 7. This list of formatting parameters is only an indication and you may get questions on flags such as ‘-’, ‘^’, or ‘0’ or use of escape character % and use %% to print %. • Some of the Java 7 topics are not explicitly mentioned anywhere in the exam topics. For example, consider two sub-topics in "Upgrade to Java SE 7" top-level exam topic "Language enhancements": "Develop code that uses String objects in switch statement", "Develop code that uses binary literals and numeric literals with underscores". In our experience, we have got questions from these two exam topics which are not at all mentioned in main OCPJP 7 exam (IZO-804)! Bottom-line: It would be a folly to strictly adhere to the exam topics listed by Oracle for theexam. Grounded on our practical experience in the exam, its a good strategy to be familiarand prepare for all the top-level topics given in the exam syllabus, including Java 7language features.  Myth #1: OCPJP 7 = (Older version of OCPJP or SCJP) + Java 7.The top in our list of myths and misconceptions is something that is surprisingly commonamong OCPJP aspirants. This is the misconception that most of you may disagree with us.But never mind, well tell you the truth!Those who are familiar with older versions of the OCPJP (such as OCPJP 6) exam or SCJPexam (such as SCJP 5) exam think that OCPJP 7 is nothing but the same old exam pluscoverage of features introduced in Java 7. It is simply not true. In two major ways OCPJP 7and its older avatars are different: OCPJP 7 is both broader and deeper than its olderversions. Lets dig deeper on these two aspects.OCPJP 7 has broader scope: This is easy to explain. The OCPJP 7 exam covers moretopics than the OCPJP 6 and 5 exams and their Sun predecessors, including JDBC,localization, NIO.2, and concurrency APIs. Yes, OCPJP 7 also covers new features of JavaSE 7, including try-with-resources statements, new APIs in JDBC, string-based switches,and binary literals; but that is only one of the differences between OCPJP 7 and its olderversions. Here is the list of exam topics in OCPJP 6 and OCPJP 7:  
  4. 4. OCPJP 6 exam topics OCPJP 7 exam topicsDeclarations, Java Class DesignInitialization and Advanced Class DesignScoping  Object-Oriented Design PrinciplesFlow Control Generics and CollectionsAPI Contents String ProcessingConcurrency Exceptions and AssertionsOO Concepts Java I/O FundamentalsCollections / Generics Java File I/O (NIO.2) Fundamentals Building Database Applications with JDBC Threads Concurrency LocalizationA considerable number of "language fundamental" topics are now moved to OCAJP 7,which is a prerequisite for OCPJP 7 exam. OCPJP 7 has more in-depth coverage of exam topics: This part is harder to explain. Oneof the objectives of Oracle when they revised the exam to OCPJP 7 is to make sure thatfewer candidates pass the exam. With this in mind, when compared to OCPJP 7, thequestions in OCPJP 7 are more difficult, there are more number of questions need to beattended within the same time period of 2.5 hours, and there is a slight increase in thepercentage required to pass the exam (see table):  OCPJP 6 exam OCPJP 7 exam Exam duration 2 hrs 30 minutes (150 2 hrs 30 minutes (150 mins) mins)Number of questions 60 Questions 90 QuestionsPass percentage 61% 65%The other minor differences between OCPJP 7 and its older versions is that all questions inOCPJP 7 are multiple choice questions. Older versions of the exam featured drag-and-dropand match-the-options style questions that are withdrawn in OCPJP 7 exam.Bottom-line: Dont look at OCPJP 7 as just incremental improvement of its older version(s),and take it more seriously to prepare well for the exam (unless youre ready to throw away$300 in the dustbin).
