good example of Javadoc

Question

is there a good example of a source file containing Javadoc?

I can find lots of good examples of Javadoc on the internet, I would just like to find out the particular syntax used to create them, and assume I can pore through the source of some library somewhere but that seems like a lot of work.

How about the JDK source code, but accessed through a 3rd party like docjar? For example, the Collections source.

That way, there's no big download.

Thats a good answer since collections where written by Josh and Neal. – cherouvim Jul 03 '09 at 17:00
My antivirus software says that docjar link is unsafe. Do you know of any other websites that feature the collections source? (I would let it slide if this wasn't a fairly high-traffic question :) – Gordon Gustafson Oct 06 '13 at 19:11

If on windows, JDK installation contains a `src.zip` file with the source code of the standard libraries. – Sri Harsha Chilakapati Dec 09 '14 at 13:18
How is it legal for a 3rd party to distribute copyrighted code? Or does the copyright allow that? – ThePyroEagle May 04 '16 at 19:38

The page How to Write Doc Coments for the Javadoc Tool contains a good number of good examples. One section is called Examples of Doc Comments and contains quite a few usages.

Also, the Javadoc FAQ contains some more examples to illustrate the answers.

that was my obvious thought but I'd have to download the whole big mess. :-( – Jason S Jul 03 '09 at 15:00

Chances are you already have it, since it comes with the JDK (though it's an installation option). – Michael Borgwardt Jul 03 '09 at 16:03

I use a small set of documentation patterns:

always documenting about thread-safety
always documenting immutability
javadoc with examples (like Formatter)
@Deprecation with WHY and HOW to replace the annotated element

ANT for example - source code browsable online: http://svn.apache.org/viewvc/ant/core/trunk/src/main/org/apache/tools/ant/DefaultLogger.java?view=co

To choose other files start from: http://svn.apache.org/viewvc/ant/core/trunk/src/main/org/apache/tools/ant/?pathrev=761528

The documentation of Google Guava's EventBus package and classes is a good example of Javadoc. Especially the package documentation with the quick start is well written.

Download the sources of Lucene and see how they do it. They have good JavaDocs.

If you are using Eclipse, then you can setup your JDK (not JRE) in Installed JREs, and then use Open Type (Ctrl + Shift + T), give something like java.util.Collections

To add to what was said, most IDEs automatically configure javadocs and source when you configure the JDK for them to use. This does not only apply to Eclipse. – ThePyroEagle May 04 '16 at 19:40

If you install a JDK and choose to install sources too, the src.zip contains the source of ALL the public Java classes. Most of these have pretty good javadoc.
