What is the primary function of Javadoc in Java programming?

The primary function of Javadoc in Java programming is to generate documentation in HTML format automatically. Javadoc is a tool that is part of the Java Development Kit (JDK) used to produce API documentation for classes and interfaces in a Java program. By utilizing special comment formats within the source code, developers can document the purpose, parameters, return values, and other relevant information pertaining to their code. When run, Javadoc processes these comments and generates structured HTML files that offer clear, navigational documentation accessible to users and developers.

This capacity to produce well-organized documentation is invaluable for programmers, as it helps both the original creators and future developers understand how to use and interact with various components of the software. The documentation generated includes comprehensive information that can be easily read and understood, enhancing the usability and maintainability of Java applications.
