Javadoc is a documentation generator introduced by Sun Microsystems (now part of Oracle) for generating API documentation in HTML format directly from the Java source code.
Over the years, Javadoc’s format has become the de facto industry standard for documenting Java classes, methods, interfaces, and so on.

The Maven Javadoc plugin uses the Javadoc tool and generates API documentation directly from the source code in HTML format.
