"Absolutely no reason" is wrong, "almost certainly no reason for most programs" is more accurate. You'll need arrays of you're writing buffers, various types of collections (B-trees, hashtables), etc.

Well, while I do agree with you (I would even add performance-sensitive code to your list. Something like int[] applied at the correct places can do a lot), if we want to be absolutely nitpicky one can just use ByteBuffers over arrays for pretty much everything.

Of course if you want to be pedantic. But no one is writing these. 99% of all code is going to use collections from the standard library.
