Java API documentation generator
Following program uses few of the important tags available for documentation comments. You can make use of other tags based on your requirements.
The documentation about the AddNum class will be produced in HTML file AddNum.html but at the same time, a master file with a name index.html will also be created.
import java.io.*;
/**
* <h1>Add Two Numbers!</h1>
* The AddNum program implements an application that
* simply adds two given integer numbers and Prints
* the output on the screen.
* <p>
* <b>Note:</b> Giving proper comments in your program makes it more
* user friendly and it is assumed as a high quality code.
* </p>

public class AddNum {

* a the simplest form of a class method, just to
* show the usage of various javadoc Tags.
* @param numA This is the first paramter to addNum method

}Now, process the above AddNum.java file using Javadoc utility as follows −
