You could also use Integer.compare(int, int) and pass Integer.parseInt(item.number) to avoid creating more Integers.

What happens if the valueOf method cannot parse the String into an Integer? Will it return null?

[MrIStillDontCare]

Or my preferred version:

items.stream()
->
.toList();

If you do not need to provide comparison to other modules.
