Type cast to Integer first

int y = (Integer)keys_tab[1];

int y = (Integer)keys_tab[1];

... or use generics; you don't need the cast then.

Oh yeah, and then they'd use the overloaded toArray(T[] t) method in Set.

Great fun isn't it? That won't work for 'T' equal to 'int'. Pure OOP! ;-)

Autoboxing is a curse.

Yep, T will have to be Integer.
Reminds of something I picked up from C# (delegates), alright I'll start a new thread about it.
