Why don't we have

This would prevent from the cast

It's too late to change the method signature now.
Sorry about my english, I meant why don't we have had ...
In other words, has there been a reason that it was not like that from the

Wouldn't following statement potentially throw a ClassCastException ?
r[i] = (T)it.next();
Apparently not. I passed in a String[] when it should be Object[] and got ArrayStoreException.
Checking the bytecode I don't see a checkcast.
Thanks, checking that out.
