heh..there are two things I really hate, no matter what OS people use - chats and java, especially together

chats are just a dumb copy of the idea of irc, and they never work all right...I hate 'em. and java...gosh, it just eats up memory and is slow and never works correctly :P
what if you try downloading some other java kit? I mean, there are blackdown and j2re (am I correct? sorry, I'm not a java expert), and I've heard these "kits" work differentially..
sorry if I have missed something with this java-stuff, blackdown and so on..but this is my guess. correct me if I'm wrong (ie blackdown is a rabbit or something else stupid hehe)
EDIT: got to add to this one more thing...I've always had java problems (I'm using j2re) with things; some work ok, but quite many don't...what's the deal? why don't they work, if java packs are "common" and java language is "common", don't people do java things well enough? hard to believe..
