Actually, the old code is more efficient than your new code.
Per the spec
https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/util/Vector.html#toArray(T%5B%5D)
Returns an array containing all of the elements in this Vector in the correct
order; the runtime type of the returned array is that of the specified array.
If the Vector fits in the specified array, it is returned therein. Otherwise, a
new array is allocated with the runtime type of the specified array and the
size of this Vector.
So your new code allocates one more array than the old code.
