Is there a place that contains the most up-to-date API listing? With a good explanation of the function of each class?
Frequently, I write actual code to perform tasks that I later find out had a class to perform that very same function for me. I try to find a class but, all too often, am not able to find it. I believe my search methods are flawed.
You're probably aware of the core Java javadocs, but they're no joy to go through and search interesting classes. Maybe the Developers Almanac is a bit easier to digest. There's also a lot of good stuff in the Jakarta Commons Lang library; it really pays to have a long, hard look at that.
