Javadoc uses the delimiters "/**" and "*/" to open and close comments, respectively. Various tags and parameters are used for different types of documentation such as for describing an author ("@author"), the version of a class or interface ("@version"), a method parameter ("@param"), the return value ("@return"), a link to other documentation ("@see"), etc. Javadoc generates output from four different types of source files, namely, source code files, package comment files, overview comment files and miscellaneous unprocessed files.
