About scjp 1.4

Scjp 1.4 is the first in a series of Java certification exams launched by Sun Microsystems. It is the first step for many programmers to become excellent Java developers.

This test tests the basic knowledge of Java and requires a deep understanding of the syntax and semantics of the language.

1. participate in training or self-study Java classic courses. If you have C language and object-oriented basics, you only need to learn sl275 and jdk1.4api by yourself. Otherwise, you should attend the corresponding training courses. I have some basic knowledge about C language and object-oriented programming language, and I also attended the sl275 + WebLogic + JSP course.

2. Determine the exam version, and clarify the knowledge points and the difficulty of the exam. Currently, the scjp exam has two versions: 1.2 and 1.4. The comparison between the two versions is as follows:

There are two types of choice questions: (1) give a piece of code to select its running result; (2) give some description statements about a basic concept to select the correct answer. A blank question is generally a correct piece of code. If you do not select an item, you can enter the running result.

The major difference between the two versions is that 310-025 contains I/O and AWT, And it is relatively easy to examine each knowledge point, the I/O and AWT contents are removed from 310-035, but the assertion test is added, and Wrapper Classes, collections, hashcode () and equals () the test is more difficult. Select an appropriate version based on your needs. During my review, I/O chose 310-035, which is difficult and a challenge for myself.

3. Exercise questions based on knowledge points. Because the certification exam is used to examine the knowledge points in the form of questions, it is one of the most effective ways to pass the exam to do more questions, through sl275 course system learning, after you have mastered the basic knowledge about the knowledge point, you must test your knowledge about the knowledge point by doing the exercises. The content of the relevant knowledge points in the book is comparatively summarized, sometimes I think I have mastered this part of content, but there may be various errors when I do the question. For example, when declaring the main () method, It should be public static void main (string ARGs []). {......}, If static is omitted during the Declaration, it can be passed during compilation, and an error message will be prompted during running. If the parameter in main () is set to string ARGs [], an error will be prompted during compilation, and similar questions will occur during the examination. Some traps may be intentionally set up, but some seemingly simple questions may fail. You are advised to manually debug and analyze the running result of a program code.

For the questions about Wrapper Classes, collections, hashcode () and equals () methods, you must carefully check the API documentation (the sun official website provides a download link, can also be viewed online on the sun website) and take notes for future reference. Consolidate knowledge points, adapt to exam questions, and identify error-prone areas. At the same time, it also plays a role in checking for missing knowledge points.

4. Download the corresponding simulated environment for practical training or online testing. Do not rush to take the test after you have mastered the knowledge points and questions. You should download a software simulating the test environment from the Internet for practical drills. I downloaded jcertify5.0, which needs to be installed and run in the jdk1.3 environment. This software can set the scope of the test for practice or test. It is a good simulation software, the questions are similar to the questions in the actual test.

The software can be used to test the problem completion situation and the knowledge points you have mastered within the specified time (120 minutes, in this way, you can review the poor knowledge points based on the test results, and perform quizzes and exercises repeatedly until you are satisfied.

5. Give yourself sufficient confidence before the test. After having done exercises and Simulated Software tests, you have confidence in all the knowledge points. In fact, there is no problem in taking the test. You have to trust your own strength and cheer yourself up, at this time, I should not do any more difficult questions. At that time, I made such a taboo. I heard that the 310-035 exam was difficult. Currently, there are not many people who have passed the exam, I was afraid that my questions during the exam were more difficult than my exercise questions. On the day before the exam, I made another set of questions, with a total of 43 questions. The pass rate was only 42%. I was very disappointed with this result, I also lost my self-confidence. I dreamed that I had been taking the test at night and the test results were terrible. I woke up the next day and had to postpone the exam. This is a painful lesson.

6. Make an appointment and take an exam. Well-known it certification vendors have designated test centers in some major cities, and Sun certification is no exception. They will sign up at the test center designated by Sun three days before the test and help you register, in addition to taking the exam, you can do other things even if you leave it to the test center.

7. Exam considerations. Arrive at the test center in advance according to the reservation time, familiarize yourself with the test environment, and stabilize your mood. The test center is equipped with a monitor in the test room, And your every move will be recorded. Therefore, the test must be fake, as soon as possible, we will eliminate the idea of "hacking. After you enter the examination system, the examination starts. The examination is divided into three phases:

(1) In the questionnaire survey before the formal examination, the given time is 15 points, there are 10 questions, and four options are provided for you to choose from, it mainly investigates your knowledge about the knowledge points to be examined by scjp, for example, you are proficient in the definition of arrays and classes, understanding, but need help or not understanding, the answer to this part of the content does not affect your score. If you understand the meaning of the question, you can choose according to your actual situation. Otherwise, you can select either of them at will, continue to the next step until all the problems are completed;

(2) The formal examination lasts for 120 minutes. The number of correct answers (for example, choose two) is displayed in the question area, and the next question is followed by the next question, click the exhibit button to view the Code provided by the question;

(3) The questionnaire survey after the question is completed does not affect your examination results. After the questionnaire is over, you are about to be nervous and excited. Now you can view the test results. The examination system lists your answers to each knowledge point. If your score exceeds the specified bottom line, the result is pass.

The moment you get the Test Result Notice is exciting. The general feeling after the test is that scjp certification is not as difficult as you think, as long as you are fully prepared, it is not a problem to obtain the scjp certificate.
