I’ve seen pointers here and there to a site called javadocs.org. When you type in a class name (or package name), it will bring up the JavaDoc for that class. What I find amazing is that the site is somewhat redundant, in that Google’s index is good enough to take care of this for you most of the time. For example, check out the first result from Google for these searches:
arraylist. If you want to really be impressed, try out
vector. (Google doesn’t return the JavaDoc for those classes as its first result, but you can see it on the first page.) Including the package name in the search is just cheating, you get a guaranteed hit. I used to have tons of JavaDoc bookmarks, but the miracle of search engines (Yahoo is just as effective as Google it seems) has released me from that burden.
