Why doesn't this work?

Ok,
So I have this simple code:
String s = "9";
int i = 9;
int k = i + Integer.intValue(s);
========
Now shouldn't Integer.intValue convert String s to a primitive so it can add it to i?
Instead Java finds java.lang.String instead of int.
What's the logic behind this?

intValue is an instance method not static.
Doing this should work:

Another possibility is Integer.parseInt which avoids creating the extra Integer object:
