Enumeration type (also called enumeration) provides an effective method to define a group of named Integer constants that can be assigned to variables. For example, if you must define a variable, the value of this variable indi
of similar products in a factory class for instantiation, which is similar to the current workshop assembly line. One assembly line is responsible for producing similar products, different products need another pipeline for production. The factory model is used to create factories for subtle products, such as individuals.RealIn the wage calculation process, we still need to Calculate taxes, funds, and other operations. If we use the factory model for design, it will become complicated. How can
Directoryinfo and fileinfo are directory and file functions. In addition, they make it easier to traverse the relationship between files and directories. For example, you can easily obtain the fileinfo object of files in the directory represented by the directoryinfo object.
Note that the Directory class and file class only provide methods, while the directoryinfo and fileinfo both provide methods and properties. For example, the file class has a separate getattributes () method and setattribute
