In their own words
Javadoc
Javadoc creates HTML API documentation from Java source files and is installed with the Java Development Kit (JDK). Its standard doclet describes public and protected Java types and members, including classes, interfaces, constructors, methods, and fields. It can process packages, individual source files, or both, with an option to include subpackages recursively. Alternate doclets can change the content and format of the generated output, while taglets add support for custom tags in documentation comments. The standard doclet includes DocLint to help identify common comment problems, but DocLint does not check conformance or repair errors. Oracle cautions that generated output may pose issues if it is non-conformant or contains executable content such as JavaScript. JDK 25 downloads are listed for Linux, macOS, and Windows. JDK 25 binaries are free under Oracle No-Fee Terms and Conditions through September 2028; later updates use a license that may require fees for production use beyond limited free grants.
