For programming languages, a good coding style can not only generate effective framework encoding at the beginning of programming, but also make our coding clearer and more standardized. However, as mentioned by the author in this article, although the coding style of some Java programs is widely used, it will have a n

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

This is a list of 10 more refined Java coding practices than Josh Bloch's valid Java rules. Compared to the list of Josh Bloch, which is easier to learn and focus on daily situations, this list will include uncommon situations involving API/SPI design and may have a great impact. I have encountered this in writing and maintaining jOOQ (SQL for internal DSL Modeli

I often encounter java coding problems at work. Due to lack of research, I cannot give a definite answer. I checked some information online this weekend and made a summary here. Question 1: What encoding should I use to read files in java? Java can read files in two types: byte and character. Byte reading uses InputStr

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

With the development of the computer, the world in order to adapt to their own language and character will design a set of their own coding style, it is because of this disorder, resulting in a number of coding methods, so that the same binary numbers may be interpreted as different symbols. In order to solve this incompatibility problem, the great creators want Unicode encoding in the timely life!!UnicodeU

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

100 times the latter, but it does use the same number of digits in the binary. Can do better, the method is variable length coding, the guiding principle is high frequency with a shorter number of digits encoded, low frequency with a longer digit code. Huffman coding algorithm is to deal with such problems. Huffman coded Java implementation The main data struc

1. Overview This article mainly includes the following aspects: Basic coding knowledge, Java, system software, URL, tool software, etc. In the following description, the word "Chinese" is used as an example. We can see that its gb2312 encoding is"D6d0 cec4", Unicode encoding is"4e2d 6587", UTF Encoding is"E4b8ad e69687". Note that the two words do not have iso8859-1 encoding, but they can be represented by

1. Overview This article mainly includes the following aspects: Basic coding knowledge, Java, system software, URL, tool software, etc. In the following description, we will take the word "Chinese" as an example. We can see that its gb2312 encoding is "d6d0 cec4" and Its unicode encoding is "4e2d 6587 ", the UTF code is "e4b8ad e69687 ". Note that the two words do not have iso8859-1 encoding, but they can b

Coding specifications are important for developers, for several reasons:1. In the life cycle of a software, 80% of the cost is maintained2. Virtually no software, throughout its lifecycle, is maintained by the initial developer3. The coding specification can improve the readability of the software, allowing programmers to understand the new code as quickly and thoroughly as possible.4. If you publish the so

Please contact me if you have any questions :) Coding FAQ (PL/SQL and Java)1. the PL/SQL data type is incorrect. For example, aac001 is of the varchar2 type, but it is not included in ''. Although the program can be queried, it poses a hidden risk for future performance problems.Select aac002 from ac01 where aac001 = 123456;Select aac002 from ac01 where aac001 = '000000 ';2. The code is too long.No matter i

Chinese characters use three bytes. Note that although UTF is used to use less space, it is only relative to Unicode encoding, and using GB2312/GBK is undoubtedly the most economical if it is already known to be Chinese. On the other hand, it is worth noting that although the UTF encoding uses 3 bytes for Chinese characters, even for Chinese-language web pages, UTF encoding is more economical than Unicode encoding, because the Web page contains a lot of English characters. Second,

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?
