directly to the client, and if the program specifies the encoding format for the output, it is exported to the browser in the specified encoding format, otherwise the default iso-8859-1 encoding format is used. The process flow chart is as follows: 3. The database sectionWe know that Java programs are connected to the database through the JDBC driver, and the JDBC driver defaults to the ISO-8859-1 encoding format, which means that when we pass dat

Often encountered in the work of Java coding problems, due to lack of research, always can not give the exact answer, this weekend on the Internet to check some information, here to do some summary.Question one: What encoding should I use to read a file in Java?The way Java reads files can be divided into two categorie

characters to the database, JDBC first converts the data in the Unicode encoding format inside the program to the ISO-8859-1 format, and then passes it to the database, when the database saves the data, it is saved by ISO-8859-1 by default, so this is why the Chinese data we often read in the database is garbled. 3. Several principles that must be clarified when analyzing common Java Chinese problems First of all, after detailed analysis above, w

Coding | Problems Java language default encoding is Unicode, and we Chinese commonly used files and databases are based on GB2312 or BIG5 encoding, how to properly select the encoding method and correctly handle the Chinese character encoding? This article will start with encoding common sense, combine Java programming example, analyze above two questions and pro

has been trying to figure out the coding problem in Java, but also read some articles on the internet, but still foggy. It was not until recently that I saw Fanglixun's web course that I understood a little.Keep a record of your understanding and see if you can be clear about it. The first question: I define a string in Java code, what is it encoded?

());} Alternatively, your code can return the clone of the exposed object. Check local methodThe local method is a Java method, and its implementation is written in another programming language, such as C or C ++. Some developers implement local methods because the Java language is slower than many compiled languages even when using the real-time (just-in-time) compiler. Others need to use local code to i

Unicode encoded.But the code conversion is not negative negative is so simple, here we can correctly convert back, because Iso8859-1 is a single byte encoding, so each byte is converted to a String as is, that is, although this is a wrong conversion, but the encoding does not change, So we still have a chance to convert the code back!Summarize:So, when we deal with Java coding problems, we need to be clear

Often encountered in the work of Java coding problems, due to lack of research, always can not give the exact answer, this weekend on the Internet to check some information, here to do some summary.The first thing we need to know is:(1) In the computer disk storage is a byte, the network is also transmitted bytes;(2) The so-called encoding, refers to the characters encoded into a specific encoding format of

In this paper, we describe the method of Base64 encoding for utf-8 of Chinese strings by JS. Share to everyone for your reference, specific as follows: String to encode: "Select username from user" Using Java for encoding, Java programs: String sql = "Select User name from user"; String encodestr = new String (Base64.encode (Sql.getbytes ("UTF-8")); Coding
