Sun java certification Q &

One of the most important tasks for today's aspiring people in the computer industry is to learn Java! So how should Java programmers and Java developers take the test, how should they take the test, and what should they pay attention to during the test?

With the rapid development of the IT industry, obtaining authoritative certification provides more and more opportunities for personal development. Sun has three types of Java certifications: Java programmers, Java developers, and Java2 Enterprise-level designers. Currently, Java certification exams in China are only the first two. Among them, the Java programmer certification test with Sun's designated Java SL-275 as the teaching material, the examination number is 310-025; Java developers certification test with Sun designated Java SL-285 as the teaching material, the exam number for the automated test is 310-027.


Java programmer Certification


1. How can I obtain Sun's Java certification?

If you want to obtain Sun's Java certification, you must pass the Java programmer (SCJP) examination. The authorized Training Center's Java programmer courses can help you learn Java programming knowledge and skills in a short period of time, and accurately grasp the test site.


Ii. What groups does Java certification training target?

Some people often ask: I am unfamiliar with the Java language and have no foundation for programming. How can I get the Java programmer certification? Some people who specialize in program development or even Java development often hesitate to take the test without being trained? In fact, in principle, training and exams are completely independent, and you can register directly for the certification exam. However, the Java certification test sites are not similar to other disciplines, and they are completely different from our daily Java programming, therefore, it is blind to learn by yourself or rely on your own programming. In the training courses for Java programmers, the instructors will aim at the various types of questions that may be encountered during the examination to help students quickly and accurately grasp the exam points. If students do not have a good grasp of what they have learned in a short period of time, they can listen again for free.


Iii. What services does Java certification training provide?

In order to meet the training needs of the majority of students, so that everyone can learn the knowledge more quickly and obtain certification, the lecturer will use Sun's designated teaching materials to systematically, completely and comprehensively describe the course content, based on the depth required by each knowledge point, the students are guided in a hierarchical, important, and purposeful manner. At the same time, the analysis and explanation of various questions can help students understand the Certification Examination intuitively and accurately.


4. How to take the Java programmer Certification Examination?

After you have made sufficient preparations, you can start taking the test. First, you need to register the candidate ID at the test center two days in advance and make an appointment with the test center staff. The examinee must take the test on time and carry his/her ID card. The test result is displayed after the test. The certificate issued by Sun will be sent to the address registered by the examinee via email within two months after the examination.


5. What are the test points for Java programmer certification?

Java programmer certification test to Sun Company SL-275 Original English teaching materials as the standard, need to master and as the knowledge points of the Test content are: Declaration and permission control, flow control and exception handling, garbage collection mechanism, basic syntax, operands and symbols, overload, overwrite, running type, object-oriented, thread, etc. In addition, there are Java. awt, Java. lang, Java. util, Java. common classes in io packages.


6. What are precautions for the Java Certification Examination?

A total of 59 questions in the JavaSL-275 examination, passing the score of 61 (answer 36 questions ). The time is 120 minutes. You can view any question at any time before submitting the exam. The question type can be divided into multiple choice questions and multiple choice questions (which can be determined by single choice or multiple choice boxes). multiple choice questions indicate several correct answers to the question.


7. What materials can help students learn?

There are many books related to Java tutorials on the market, some of which can help students better learn and master the knowledge points that Java programmers should possess, such as Java, Java, and Java programming. However, sometimes some content in these books may differ from the textbooks specified by Sun. In this case, we should refer to the reference of the textbooks. Of course, both teaching materials and books purchased by myself are just a systematic description of the Java language. to grasp the key points and difficulties of the examination, the content of the training course instructor should also prevail.



Java developer Authentication

After obtaining the programmer's certification, you can continue to learn to obtain the Java developer (SCJD) certification. Compared with Java programmer authentication, it is more difficult for developers to master knowledge and obtain certificates. Because of this, the developer's certificate is more valuable to the identification of personal abilities and personal career choices. The following section describes the Java developer certification exams.


1. Java developer Certification Course

Lecturers who teach Java developer certification courses are experienced in development and knowledgeable. During the five-day training course, we not only talked to students about Java program architecture and programming skills, but also instilled Java object-oriented programming ideas. The students will learn how to develop an actual two-tier/multi-tier Java Intranet application and related platform porting problems from the platform.


The specific content of the course includes: Explaining the objectives of each stage of the software development cycle, using appropriate Java program types, understanding the basic elements of API design, and determining program components according to the functional requirements of the project; describes the design and design principles of relational databases; Understand JDBC and ODBC and their usage; create good GUI Design Principles to design your own user interface; use Socket connection to transmit data in an appropriate format, create a multi-tier Java applet or application; learn about porting issues between Solaris and Windows platforms.


Ii. Java developer Certification Examination

Java developers are divided into two parts: program design and machine test. The programming part is not limited. After you register, you can download the exam questions from the specified website and design the program based on the questions. Within the specified period (1 year), the examinee must return a self-designed Java program. However, in general, candidates will send the program back within two to three months. The quiz part will answer questions for the program. As long as you really understand and master the process and content of the design program, there will be no questions to answer these questions. The developer's certification examination is an assessment of a Java developer's comprehensive ability. Through the course study, it will cultivate a programmer's independent programming ability, this certificate is also a powerful proof of this ability.
