Introduction to Java Basics Essay (9) JavaSE Edition - Documentation Comments

In the previous section, we wrote about the definition and use of some static variables and static methods, as well as the differences between them and non-static. In this section, we will add:

If all methods in a class are static and have no member variables, you need to Restrict the corresponding class. This class cannot create objects. The specific operations are as follows:

PRivate ArrayTool(){}

//The methods in this class are all static, so this class does not need to create objects. In order to prevent others from creating objects of this class, you can make the constructor of this class private.

1. Documentation comments

Use the javadoc tool in the java fake machine to generate documentation comments, and use the documentation comments in the code to generate them.

Note:

1. Each compilation unit (class file) can only have one public class
2. The name of the public class (including upper and lower case) must have the same name as its class file.
3. Public class does not need to exist in a class file (*.java).

Use javadoc tag:

javadoc tag consists of "@" followed by the tag type and special annotation reference
javadoc tags are as follows:
@author indicates the author who developed the module of this class
@version indicates the class The version of the module
@see Reference steering, that is, related topics
@param Description of a certain parameter in the method
@return Description of the return value of the method
@exception Description of exceptions that may be thrown by the method
