The record

Purpose: Javadoc generates HTML API documentation pages from Java source files.
JDK inclusion: The Javadoc tool is installed with the Java Development Kit (JDK).
Standard output: The standard doclet generates HTML pages describing public and protected types and members, including classes, interfaces, constructors, methods, and fields.
Custom output: Javadoc supports alternate doclets that define the content and format of generated output.
Custom tags: Custom tags in documentation comments are supported through taglets.
Inputs: Javadoc can document whole packages, individual Java source files, or both, and can recursively include subpackages.
Validation: The standard doclet provides DocLint to help detect common problems in documentation comments, but does not validate their conformance or correct errors.
Output safety: Oracle advises users to be aware of problems that may arise from non-conformant output or output containing executable content such as JavaScript.
Operating systems: Oracle lists JDK 25 downloads for Linux, macOS, and Windows.
License limit: Oracle says JDK 25 updates are free under NFTC through September 2028; subsequent updates use the Java SE OTN License, which may require a fee for production use beyond its limited free grants.
