Java developers

I've been listening to some of the Javapolis 2004 presentations, which have been made available online by Javalobby (registration required, but I think it's worth it). They're interesting - some topics I knew about but was interested to hear what they were saying, others I didn't know about and got a good introduction.

My favourite so far is Rod Johnson J2EE without EJB, which should be considered required listening :-)

Anybody tried to addAll a collection to a TreeSet?

Say,

SortedSet ss = new TreeSet();

ss.addAll(Arrays.toList(new int[] {3, 17, 90, 1, 27, 2005}));

Try it, you'll find it amusing.
