I believe that when you apply, the first level is a written test. Even a very experienced engineer is not a smooth pass. If the written test is not good, it may not be able to interview, even if it is able to interview, the examiner will not impress you. Very good, there will be a lot of questions. It is estimated that it is difficult to eat. Of course, if you are a very experienced master, it is possible to pass the interview, but it will also affect your treatment.
It is possible that someone will ask, if you are a Java engineer having a certain development experience, how could it pass a written test, in fact, this possibility is existing, and it is very big, because the topic of the written test is very basic, some are all You usually have never been noticed, maybe you have used it in development, but don't know what is, for example, write JSP is definitely used in Out, Request, etc., but not necessarily, they call JSP's built-in object, if Question: What are the built-in objects of JSP, you don't have to answer, so in the case of developing Javabean, you usually use ArrayList, Hashmap, etc., but you don't necessarily know the difference between ArrayList and Vector, HashMap The difference between HashTable, maybe you are mixed in development, nor will it be wrong, but the efficiency will be greatly reduced. If you mix in multithreading development, you may have an error. Maybe these are small problems, if there is a certain basis Look at the book, I will know, but I can't answer or answer in the written test may affect whether you can interview, if the interview company is the company you think, because these details, I can't go in, isn't it? Unfortunately.
I wrote this article is to let most people regret, more than one joy after the interview, maybe someone will ask: You will work a few years, just make a summary here, what you said in the written test Maybe it? I want to say that I have a short work hours (graduated in 2002), but the big and small company has a lot of interviews, sometimes because of the small problems on these written tests, it is not possible to go. The company, the result, I summed up the interview and loss of the interview, re-read the basic knowledge, and I successfully apply a big company, and I have a relatively high salary of the same work experience. The reason why I spend time. Summary, the purpose is to get into the company you want, and get the salary of yourself. Maybe these summaries have brought to you than a few technical articles, because it is directly with your interests, future hooks. This article applies In terms of development capabilities but Java, J2EE foundation is underneuric and looking for friends from Java, JSP, J2EE development, and maintenance. If your time is sufficient, it is a comprehensive look, if time is tension, you can look at it. I'd better look at the problem.
Ok, gossip doesn't say much, listed below, I have encountered problems in my written test, and the extension of these issues, the problem is based on the basics, the answer is not here, check the information, see the book can solve, I am This solemn statement: It doesn't mean that the following questions will be able to interview, it is a master, just don't read the book, my summary is just to improve your written test, it is not very solid, time is very tight Help you successfully try. Remember: it is not universal.
Java foundation:
1, scope public, protected, private, as well as the difference
2, the difference between ArrayList and Vector, the difference between Hashmap and HashTable
3, can the char type variable can be defined as a Chinese? Why?
4, many threads have several representations, what is it? Synchronize several implementation methods, what is it?
5. Inheriting the order of execution of the class is generally a choice question, ask you what will print out?
6, the internal class implementation?
7. How to optimize the garbage recovery mechanism?
8, FLOAT FLOAT F = 3.4 is it correct?
JSP
1. What built-in objects have jsp? What is the role?
2, what actions are there? What is the role?
3, the difference between the two implementations of INCLUDE?
4, what is the difference between the two jump methods? What is the difference?
Servlet
1, talk about the life cycle of servlet?
2, the servlet version (forgot to ask which two versions) Different? JDBC, JDO
1, you may let you write a JDBC even Oracle program.
2, Class.Forname role? Why is it used?
3, what is JDO?
XML aspect
1, what parsing technology is there? Is there anything?
2. What are your aspects of XML technology in the project? How to implement it?
3. How to solve Chinese problems when using JDOM to resolve the Chinese problem? How to resolve?
EJB aspect
1. What are the contents of EJB2.0? What are the differences in EJB2.0 and EJB1.1?
MVC aspect
1, all parts of MVC have those technologies to achieve? How to implement?
Design mode:
1. Use the design mode in the development? What are the occasions?
JavaScript
1. How do I verify digital?
Corba
1. What is CORBA? What is the use?
The above is my summary, may not be all, because the time problem Time to find (9CBS / Java version) can understand, I hope to help friends who are looking for work, remind the pen test paper that is very accurate and high, may be reduced to your interview, and ask a lot less problem.
Of course, I still have to remind the software to develop, and the friends who maintain the work should pay attention to the foundation, good at summary and comparison, and how can they chase them.
