Javadoc starts with / ** and ends with * /. Each Javadoc annotation is accompanied by one or more tags, and the HTML tag can also be used within the annotation. When writing Javadoc annotations, please follow the following principles: 1. Roll the "Note Start Symbol" / ** to complete the program code for unused annotations. 2. Write an annotation content from the second line (the first line is "annotation start symbol"), and each line is annweet as the beginning, and the first signal alignment of "Note Start Symbol". 3. Insert a line of blank injury between the text and the label list. 4, the last line (not including the annotation content) is "Note End Symbol" * /. Javadoc annotation placement location: 1, class or interface: Before the IMPORT statement, the category or interface declaration. 2, method, member variable, constructor: before Method Signature). When writing annotations, try to make the first sentence become a summary of this item (in a concise text to clearly describe the use of this item). The Javadoc Toolproof will copy this summary to a summary list of the class, interface, or a member variable. The behavior of the class is far from making a line description for each method. Effective javadoc should include descriptions for the following:
1. How to interconnect 2, how to affect the status of the object 3, how to notify them to inform them of the caller and what error 4, how to handle the use of the use of multithreaded applications 5, methods Domain and its return value
