DocCheck is an extension to the Javadoc tool that reviews Javadoc comments in the source code, identifying gaps and irregularities. It produces an HTML report that separates serious problems from trivial ones, and makes "suggestions" in the form of templates that show you what is needed. (Those suggestions can then be copied into the code and edited.) DocCheck recursively examines directories, and can be instructed to ignore packages and classes using fully-qualified wildcard patterns.
