... and others would suggest avoiding finalize() altogether, too.
Both finalize() and clone() are relics from the very earliest days of Java. They aren't as well thought-out as later features. Luckily, extremely few programs really need finalize() [use weak or phantom references instead], and few need clone().
I consider cloning of arrays to be a special case. It's the most efficient way to copy a whole array, and there are no confusions with how to override the array-cloning method, because you can't.
Betty Rubble? Well, I would go with Betty... but I'd be thinking of Wilma.
