Unified common coding methods and Java Web Coding
Unified format: (UTF-8 is not required, but must be unified)
JSP:
Servlet:
Request. setCharacterEncoding ("UTF-8"); // set the input encoding format.
Response. setContentType ("text/html; charsetType = gb2312"); // you can specify the output encoding format.

Cache variableDOM traversal is expensive, so we try to cache elements that will be reused.

C # Coding Standard-coding habits
1. Avoid placing multiple classes in one file.
2. A file should have only one namespace. Avoid placing multiple namespaces in the same file.
3. A file should not exceed 500 rowsCode(Excluding the code generated by the machine ).
4. The code length of a method should not exceed 25 lines.
5. Avoid more than five parameters in the method. Use the structure to pass mu

It is a good habit to gradually develop codes.
1. Basic Principles
Mandatory principle:1. The StringBuilder must be used for string addition;2. try... Catch usage
Try {} catch {Exception e. printStackTrace ();} finally {} // It Can Be Used in the Action on the outermost layer, and will not be used elsewhere;
Try {// program code}
First, the arithmetic coding definition
It is a non-grouping coding algorithm. It is based on the whole sequence, using recursive form of continuous coding. Instead of mapping a single source symbol into a code word, the symbol for the entire input sequence is mapped to a small interval within the interval [0 1] on the real axis, and a representativ

Names)
Naming is most helpful for understanding the logical structure of a program. A name description is "what" is more important than "how. Naming can avoid exposing the underlying implementation, thus retaining an abstract layer, simplifying the complexity of the program. For example, you can use getnextstudent () in
Manchester Encoding(Manchester Encoding), also known as Phase Encoding (PE), is commonly used for LAN transmission. In Manchester Coding, there is a hop in the middle of each bit. The hop in the middle is both a clock signal and a data signal. However, in different books, in Manchester encoding, the value of the level beat expression is different, which produces many ambiguities:

The Turbo code skillfully constructs the long code with pseudo random character by the parallel cascade of two simple component codes through pseudo random interleaving, and realizes pseudo random decoding by multiple iterations between two soft/soft out (SISO) decoders. His performance is far more than other coding methods, and has received wide attention and development.
