Sometimes I think Jakarta Commons is Java’s only saving grace. Every time I do something, I check the myriad offerings of commons for an existing implementation… email (finally), file upload, command line options, etc.

It goes without saying, however, that Lang is #1. Not only does it obviate a bunch of your plumbing code, but it implements a consistent interface… and it’s NPE-tolerant!

Lang is Java done right. Everyday I find something new that I like! Use it now.
