I can find the API documentation on any classes in the sun.* packages. Where is it?
The short answer is that we provide documentation only for the public classes in java.*. We do not provide documentation for sun.* because those are the Sun-specific implementation, and specifically not part of the Java technology API standard, and are therefore subject to change without notice. In general, we don’t provide javadoc documentation for sun.* classes in order to discourage developers from writing programs that use them. For further explanation, see the next question. However, if you must have it, the documentation for sun.* is available in the doc comments in the community source code release available separately, mentioned in question A14. For example, the doc comments for sun.
