![Sample question – 1 [answer]
e) The program prints: in catch -> in finally ->
The statement println("after throw -> "); will never be executed
since the line marked with comment LINE A throws an exception.
The catch handles ArithmeticException, so println("in catch -> "); will
be executed.
Following that there is a return statement, so the function returns.
But before the function returns, the finally statement should be
called, and hence the statement println("in finally -> "); will get
executed.
So, the statement println("after everything"); will never get executed.](https://image.slidesharecdn.com/certifications-130117202905-phpapp02/75/OCAJP-7-and-OCPJP-7-certifications-25-2048.jpg)

When null is passed as second argument to Arrays.sort()
method, it means that the default Comparable (i.e., natural
ordering for the elements) should be used.
The default Compartor results in sorting the elements in
ascending order.
The program does not result in a NullPointerException or any
other exceptions or a compiler error.](https://image.slidesharecdn.com/certifications-130117202905-phpapp02/75/OCAJP-7-and-OCPJP-7-certifications-29-2048.jpg)

OCAJP 7 and OCPJP 7 certifications
This document provides an overview of Oracle's Java certification exams OCAJP7 and OCPJP7. It discusses the benefits of getting certified such as getting noticed by recruiters and proving expertise. It describes the exam topics, structure, and registration process for both exams. The key points are: - OCAJP7 is for beginners and tests fundamental Java skills. OCPJP7 tests more advanced topics and requires OCAJP7 certification. - Exams contain around 90 multiple choice questions testing both conceptual and code-based problems. - The best preparation is practicing coding, reading documentation, and taking mock exams focused on weaker topics.

- 19. What kind ofexam is it? It’s a multiple-choice questions exam The number of options would be based on the questions Can be from 4 to 7 options (typically four options) Many questions will have more than one answer to be selected! The question will clearly tell you how many options you need to select
- 20. What does thequestions test? Questions intend to test your ability to solve real-world problems Most questions would be programming questions Given a program or code segment, predict the behavior Also few conceptual questions These questions will test your knowledge and will not have any programs in it. Examples: .What are different kinds of drivers in JDBC .What are different kinds of liveness problems with threads
- 21. Example: Conceptual question Whichone of the following relationship describes the OO design concept of "composition"? a) is-a b) is-a-kind-of c) has-a d) is-implemented-in-terms-of e) composed-as Answer: c) has-a Composition is a design concept that refers to has-a relationship.
- 22. Tests your Javalanguage knowledge Questions will test your knowledge of language features and their usage Will test if you understand language features and can apply them in practical situations Most questions will be on nitty-gritty details or corner cases, or unusual aspects of the language Example:You don’t just need to understand the generics feature in Java but also need to understand problems due to type-erasure, mixing legacy containers with generic containers, etc.

- 30. Does not testyour memorizing skills! The exam tests your understanding of the Java language and library and your ability to apply it for problem solving It does not test your memory skills However, there are few topics where you may need to remember key things; examples: Letters used for creating custom date and time formats ("string patterns") for use with SimpleDateFormat class Characters used for forming pattern strings in regular expressions Format specifiers and their meaning for use in format() method in String and in printf()
- 31. Out-of-syllabus questions? Examquestions need not be exactly from the exam objectives Any topics related to the exam objectives can come in the exam For example, serialization and use of transient keyword is not explicitly mentioned in the OCPJP exam topic But this topic come in the actual exam because it is related to reading and writing streams .one of the streams is ObjectStreams and it relates to serialization!
- 32.
- 33. Code, code, code! The best way to prepare for the exam is to write lots and lots of small programs and learn from your mistakes! If possible, do some small toy projects in the topics you’re new or not familiar with. Examples: For localization, you can localize your old programs For JDBC, you can create a simple exam simulator program For I/O fundamentals and NIO.2, you can implement simple DOS or Unix commands using these Java APIs
- 34. Read, read, read! By reading more, you’ll learn more about the language features and the library. Lots of resources in the internet. Two indispensable ones are: Oracle’s online Java tutorial: Read the Java tutorial available in the Oracle website for free; you can access it at http://docs.oracle.com/javase/tutorial/; tutorial pages to prepare for OCPJP7 are available in http://docs.oracle.com/javase/tutorial/extra/certification/javase- 7-programmer2.html Java documentation. The Java API documentation is a rich mine of information. This documentation is available in web (see http://docs.oracle.com/javase/7/docs/api/) as well as shipped as part of the Java SDK.
- 35. Focus more onnew topics Take a close look at the exam objectives and grade yourself from say 1 to 10 with 10 being the highest. Prepare all the topics for which you've rated yourself as 8 or below. Focus more on the topics in which you’ve rated yourself 8 or below.
- 36. Take mock-exams Attemptmock exams Take the exam as if it were the real exam: Get a quite place where you can take the test without a break Don’t refer to any books, ask others, or check web … Prepare based on the topics where you score very low And then take another test, and so on …
- 37. Registering and takingthe exam
- 38. How can Iregister for the exam? You can register and pay at the Pearson VUE website Recommended option You can buy exam voucher from Oracle and then register yourself in Pearson VUE website You can register and pay in the Oracle Testing Center (OTC)
- 39. That’s it –All the best!
