Description: This article is original, the author contact address is: josserchai@yahoo.com. Since the Chinese issue in Java Programming is an older's all-talk, after reading many of the Java Chinese issues, combined with the author's programming practice, I found that many methods that have been discussed in the past cannot clearly explain the problem and solve problems, especially Chinese issues in cross-platform. So I gave this article, including the Chinese problem in the Class, Servelets, JSP, and EJB classes running in the console. I analyze and recommend a solution. I hope everyone will advise. Abstract: In-depth analysis of Java programming Java compilers on the Java source file and JVM on the encoding / decoding process of the Class class file, through the resolution of this process, the root cause of the Chinese problem in Java programming, finally given The proposed optimized method for solving the Java Chinese issue. 1. The source of the Chinese problem is the initial operating system supported by the system. The encoding supported by the single-byte character encoding, so that all handlers in the computer are initially processed by single-byte encoded English. With the development of the computer, in order to adapt to the language of the world's national nation (of course, our Chinese characters), people have proposed Unicode encoding, which uses double-byte coding, compatible with English characters and other ethnic bodies, so currently Most international software uses Unicode encoding. When the software is running, it obtains a local support system (most time is an operating system) default supported encoding format, and then converts the Unicode's unicode to the local system default support. The format is displayed. The JAVA's JDK and JVM are the case. JDK I said here refers to the International version of JDK. Most of our programmers use international JDK versions. All JDK refers to an international JDK version. Our Chinese characters are double-byte coding languages. In order to allow computer to process Chinese, we have developed GB2312, GBK, GBK2K and other standards to accommodate computer processing needs. Therefore, most of the operating systems are customized to meet the needs of our dealing with Chinese, they are customized, which use GBK, GB2312 encoding format to display our Chinese characters correctly. For example, Chinese Win2K defaults to GBK coding display. The encoding format of the save file in Chinese Win2k is saved. The encoding format of the save file is also GBK, ie, all files saved in Chinese Win2k It uses GBK coding by default. Note: GBK is expanded based on GB2312. Since the Unicode encoding is used inside the Java language, there is a problem with the encoding format supported by the Unicode encoding and the corresponding operating system and the browser, this conversion process has a series of steps. If any of these steps, the displayed Chinese characters will be garbled, this is our common java Chinese problem. At the same time, Java is a cross-platform programming language. Some people put the Java program written on Chinese Win2k to run on English Linux). This transplant operation will also bring Chinese issues. Also, some people use English operating systems and English IE and other browsers to run programs with Chinese characters and browse Chinese web pages. They do not support Chinese, and they will bring Chinese issues.
