Production experience:
1. You have to learn how to use JAVA DOC in English. Don't think that there is a Chinese document for you to read, so you will always run behind most people.
2. Beginners who use online forums and search engines always like to ask questions. It is recommended that you search online before answering. Most of the questions can be answered online because others have asked similar questions before.
3． Proficiency in Commonly Used Classes If you want to truly enter the industry, you must be proficient in some common classes. Don't ask to check JAVA DOC for a common method during the interview, which will lead to missed job opportunities. A year ago, I had this experience.
4. Thinking about the production ideas of some common website functions, such as thinking about how the article system realizes the mixed arrangement of pictures and texts. You can take a look at some production ideas for large websites.
5. Tutorials and examples on the SUN website. There are many good tutorials here, including examples of using some methods of classes in the JAVA class library.
Difficult encounters:
1. If Chinese issues were not developed on the English version of the operating system, this would not be regarded as a big deal. Until now, some problems have not found good solutions. For example, TOMCAT started in the service under the control panel will generate a DOS window after running. The two startup methods have different support for Chinese.
2. I don’t know whether the problem of bad pictures on the website is a problem with the network server or a problem with TOMCAT. There will be bad pictures.
at last:
Congratulations on using JSP/JAVABEAN technology to develop a dynamic website for the first time. After many hardships, it finally paid off! In the past two years, I have frequently visited DEV-CLUB (CHINAASP), CHINAJAVAWORLD, and JAVAUNION, and I have benefited greatly. Thanks!
