I think I may have committed a deadly sin. I didn't javadoc-comment my code as I wrote it.
Now I'm sitting on close to 50 undocumented files (though not all of them are "public" and require javadoc). I am wondering if there is any software which will step through my source code and let me choose some methods to prepend with javadoc-style comments, and then write out a little skeleton comment, perhaps just with "write description here" placeholders for the method and any applicable @param and @return attributes.
Does this exist or am I going to have to write it myself/do it all by hand?
