The first method:You can use the Javadoc tool. It can be extracted from the program source code such as classes, methods, member variables and other documents to form an API supporting documentation. However, when writing code, it is necessary to comment on certain specifications. The development documentation for the code can be generated at the same time through the Javadoc implementation tool. The Javadoc tool is located under the C:\

Parallel substitution serial: Data migration load Balancing time space: CPU and memory space swap: Caching Java Program OptimizationString: Consists of a char array, an offset, and a string length. Its true length is positioned and intercepted in this char array by offset and length. Substring can easily lead to memory leaks. For string addition, if you use string addition directly, t
