hi all ! I need to get some doubts clarified!

I'm going to buy the enthuware exams to practise for the OCA 8 exam . But I am a little nervous .....

1. Will the enthuware questions be similar to Jeanne and Scott's book chapter wise Review questions ? If I am able to do Jeanne and Scott's study guide book's  chapter wise Review questions, will  I be able to solve Enthuware too ?

2. Will the enthuware questions have a lot of extra and difficult topics ?

3. Can I start off directly with the standard tests or must first do the objective-wide tests ?

4. And is there any validity date on the availability of the purchased enthuware exams ? I mean once I purchase the exams, will there be any deadline date after which, I won't be able to view or access the exams bought ?

From what I gather:
  • Enthuware questions are harder then the real OCA questions, and they are word the same was as the OCA exam. There are stories of people getting 70% on Enthuware practice tests and then getting 90% on the OCA exam.
  • I  just picked this up last week and I should have gotten it sooner as there are at least seven standard tests,  four practice tests, eleven objective-wise tests. Ideally you want to wait at least one day between doing tests so that you can learn from your previous attempt(s).
  • If you can answer Jeanne and Scott's questions then you can answer at least some of the Enthuware questions. When I picked up Jeanne and Scott's book I registered it online at their web site and they have a few online practice tests as well as flash cards and end of chapter tests online. One thing to note is that you should not take the same test again and again with the same questions as you will come to memorize the questions and answers, which will leave you with overly confident
  • You can do the tests in any order that you want to do them it


  • This is how the Enthuware team suggest you use this tool:

    "The topics covered are the topics that you should know for the most part for the exam.

    Getting Started  In the "Test View" tree on the left, there are multiple categories of tests - Standard Tests,  Practice Tests, Objective wise Test, and Custom Tests. Each category has multiple Tests. To take any of these tests, just double click on the Test node. For example, double click on Test 1 under Standard Test to start Test 1. You will be asked to enter a name for this attempt. You can take any test any number of times. Each attempt is showed right under the Test. For example,  if you take Test 1 with the name, First Attempt, you will see a node named First Attempt under Test 1.  

    Standard Tests mimic the real test in terms of topic distribution, toughness level,  and time.  You should start with the first standard test. After taking the test,  go through the explanations for each question...even for the questions that you answered correctly. This is because we try to put lot of useful information in the explanations, which can help you understand the concept better. Identify the topics in which you scored least and study those topics from any book. Develop some sample programs to test out the concepts if necessary.  Only after you are comfortable with topics on which you scored least,  you should attempt the next test. Your goal is to increase the scores on these topics on the next test. If you are able to pass all the tests comfortably, you will pass the real test with flying colors!  

    Practice Tests are useful when you want to check your level of preparation. It contains Easy, Tough, and Very Tough tests.  It may also contain a Most Missed Test. This test contains questions that are answered wrong the most by all the users of this question bank. To use this test, you need internet connection because it fetches the list of most missed questions dynamically from our server.  

    Objective-wise Tests are useful when you are following a book and after each chapter/topic/exam objective, you want to solve questions only from that topic.  
    Finally, if you need something other than all the above types of tests, you can customize the tests under Custom Tests. For example, if you want questions on two topics, just right click on Custom Tests node and click on "Create New Test Criteria".  Give a name to the Test Criteria (e.g. My Test on topic 1 and 2). It will open up a Criteria set up screen which is self explanatory. Once you create this custom test criteria, you can take tests on this criteria just like the other tests. In fact, all other tests are nothing but pre-defined test criteria!

    Note: All the questions delivered by various tests come from a single question bank. Thus, if you take an Easy Test and then take a Standard Test, you might get questions that you've already seen. However, tests under Standard Tests are unique among themselves  (i.e. questions in one standard test are not repeated in any other standard test) and cover all the questions from the question bank."

    Can someone suggest me what would be a decent score on each of the enthuware practice exams, to say one is ready for the final exam ?

    Well according Enthuware as listed in the previous post:

    "If you are able to pass all the tests comfortably, you will pass the real test with flying colors!"

    Now it is a bit unclear as to what pass may mean. For OCA 808 you need to get 65% or better to pass, however if on most other tests (going back to college and high school etc) you only need 51% to pass.

    I would suspect that if you get in the 60s then in the Enthuware tests that you would get at least enough to get the needed 65% for the OCA 808 exam. Whatever you do, don't sell yourself short. By which I mean, don't just try to pass the test to get the certification, but try to get at close to 100% as you can. The reason is that if you only try for 65% and you answer a question or incorrectly more then your quota allows for then you will not get your certification. However if you try for 100% and you answer a question or two incorrectly then you will still most likely get your certification.
    It's been said by many people that if you go into a test thinking "I'm going to fail" then you are most likely going to fail. So go into your test thinking "I'm going to get at least 90%" and you have a better chance of reaching that 90%.

    I think that I should point out that I'm nervous/anxious about my upcoming OCA 808 certification as well which I have scheduled for late August 2017.
    By the way, if you haven't scheduled your test yet don't worry, you can reschedule the test at least once or twice for free as long as you do it well enough in advance. I rescheduled mine from early August 2017 to late August 2017 and it only took a few moments. However rescheduling it subject to testing area availability.

    One other thing @shambhavi sham, I don't think that Jeanne and Scott's go over dividing by 0.0 as listed below:

    Line 3 does not throw an exception. And if you change line 1 to

    You get a different answer. Finally if you change line 1 to

    You get a different answer.

    However none of the above produce any exceptions.
    I would just hate for you to loose a mark on what is seemingly an easy math/exception question.

    i would like to know, for COMPILE TIME CONSTANTS, memory is allocated at runtime only right ? But the compiler keeps track of these compile time constant variable's values right ?

    It's probably best that you start a separate thread/discussion regarding compile time constants as this does not seem to be related to Enthuware.

    I know that I do not have a valid answer to your question about compile time constants.

    @Pete Letkeman , may I know the reason for this behaviour of divide by zero with floats ?

    I just know that it does, I do not know why. And it's more then floats, it's floats or doubles. Please keep in mind that as soon as you include a float in the equation then the result will be a double. This means that



    There are other math related rules such as:
  • any time you do math with only byte, short, char, or int the result will be int
  • any time you do math with a long the result will be long, unless you do math with a float or double in which case the result will be double


  • However as with most things there are exceptions to those rules as well. For example:

    But what if you use final? Then things work out just fine:

    @shambhavi sham,

    I suspect that if you to know more about NaN, -Infinity and Infinity as it relates to decimal division that you will need to start a different thread. Most people will probably think that questions in this thread relate to OCA Enthuware in some way.

    I passed OCA8 last year and OCP8 yesterday, I bought both Enthuware practice packs. I have never made a better decision in my life. All enthru test questions have detailed explanation on why the correct answer is the correct and why the others are not correct. Also, they both include a "Last Day Unique Test" that is really really similar to the real exam, although I think that Test should be done 2-3 days before the exam to let the practice sink in a bit. I can only recommend!

    If you consistently score 80+% on Enthuware mock exams (in exam mode of course, meaning using the appropriate time limit and using nothing but pen & paper), you should comfortably ace the actual exam.

    Pete Letkeman wrote://this won't compile even thought the result is in byte range because any time you do byte, short, char math you get an int result.


    How is this an exception to the general rule "any time you do math with only byte, short, char, or int the result will be int"

    Pete Letkeman wrote://this will compile fine because the system is assured that the result is in the byte range.


    The final keyword is the big difference with the previous code snippet (the one with the non-final byte variables). That turns an ordinary variable into a compile-time constant (in this case). Here is a very, very, very important rule: The compiler doesn't execute any code! So every compiler error you get, is because the compiler knows something is wrong without executing any line of code.

    So in your first code snippet, the compiler doesn't know (nor care) about the values of a and b. You know the sum of both variables is within the byte range, but the compiler doesn't know (nor care). And that's why the compiler handles a+b as an int and requires you to add a cast if you want to assign it to another byte variable.

    But once you add final to both variables, you create (in this case) a compile-time constant. And like this name already suggests: the compiler is aware of the actual value of this variable! And it also knows that the sum a+b will fit into the byte range and therefore will add the cast to byte for you. In fact, the compiler will probably perform one of its optimizations and will execute the sum at compile time (and thus after compilation, line3 will probably be byte c = 30;). So that's a very slight performance improvement, since at runtime the addition doesn't need to be executed anymore as the sum was already calculated at compile time.

    In case, I'm not able to do well in the first attempts of mock tests , after correcting my mistakes, again when i take up the mock, if I'm able to get a good consistent score such as 80 , will it be ok ?

    Probably not! Because by retaking the same mock exams over and over again, you will answer questions correctly only through memorization and not by actual knowledge. That's the reason why you should not rush through all mock exams at once...
