Question

I am looking through the code someone wrote a while back and wondering whether I am missing something here

Assuming

List<Integer> runUids = new ArrayList<Integer>();

and later on as part of a loop

int runUID = runUidsAL.get(i).intValue();

Is there any reason why intValue() needs to be called here?. Don’t think it’s needed here. Do you?

Answer 1

You didn’t say so, but I assume that runUID is an int.

It’s not necessary to call intValue() explicitly on the Integer object returned by runUidsAL.get(i); Java will do this automatically by auto-unboxing.
