Sun SCJP Certification exam experience exchange
Earlier test had Sun Certified Java Programmer, finished and has been busy, now, share the experience of the examination with you.
1) Java 2 Plat Form examination subjects is 310-025, has 59 questions, the passing line is 61%, that is the correct answer to question 36. Examination time is 90 minutes. Particularly repulsive is before the exam have a Agreement, even the time you read it was also taken into account. I began to do not know, is still read slowly, suddenly discovered that we have spent 3 minutes, and quickly begin to make title. Estimated Agreement Nothing important things, you can skip. Barely enough time, I probably spent 60 minutes for End title, leaving more than 20 minutes to check, even given the 3-5 questions I found errors are inadvertently falling into the trap set by the subject, they must be leave time to check. Unfortunately, the remaining 10 questions I did not have time to check around.
2) very narrow scope of the examination. Are basically the basic language knowledge, such as Swing, Jsp, Servlet, Jdbc, Beans and so on do not involve. Everyone can go to Sun website to download the examination outline. Narrow the scope of the examination does not mean easy, on the contrary, some very basic things over and over again,change it quickly, but more difficult.
3) only multiple-choice examinations, including radio and check. Most complex topics clearly has a few answers, not wrong.
4) the impression that almost all of the questions involve more than 2-3 points of knowledge, almost no one can see the answer on the topic. 70% of the test is for you for some procedures, and then run the results question the value of a variable. This topic is very easy to fall into the trap of accidentally being spent. 20% of the subject is to give you a few declarative sentence, choose the right one. These declarative sentence is a very partial examination of things is very partial, not good FOR. Basically, my experience is: If a subject can see the answer immediately, please look at the subject, in most cases is that you fall into the trap. If a topic is very specific you can look up what he wants to test your knowledge points, and that the subject on completion of half of the. The worst is to know what topics you want to test, but have forgotten or did not review the details of the relevant knowledge, so wild guess the guess.
5) One of the highlights of the examination Inner Class. Impression that more than half of the subject and his big Class sets, such as small Class. Review when I spent a lot of time in it, thinking that they know deeply, and the results of the examination is still a problem. Must be a thorough understanding of the relevant definitions, grammar, especially the usage of a wide range of Modifier. There are many very special Modifer rules. These rules must be mastered and borne in mind.
6) Another focus of the examination cycle statement. I thought of the statement is very familiar with the cycle control, resulting in some very partial examination test the usage of very special, although as can be made slowly, but wasted too much time in it is a real pity. Everyone a good look at the book.
7) others as: Casting, IO, Layout, Even Handling, AWT, Thread, Garbagecollection, Math Class and so on, there are a number of questions.
8 The examination questions are not reflected almost entirely practical application. If I have a Java compiler in the side, almost all the questions can be easily resolved. I feel that Sun hopes Java candidates can be as familiar with the Java compiler, like the special grammar and special rules.
9) I have collected many mock exam questions and the questions, there are nearly a thousand questions. It is strange that less than 10 questions in the examination, it appears that Sun’s exam item bank may be implemented is a dynamic question bank, test questions are not back, what hope is passed. And test procedures for a symbol change only slightly, the result is completely different questions, many topics unreliable. Therefore, everyone must be in a certain practical experience on the basis of a properly seen through counseling book, more questions, more analysis of questions, to think more about in order to more easily pass the exam.
10) regardless of how to assess the U.S. certification exams, anyway, a few more test certificate is not a bad thing, at least pay more convenient to find a job.
