The survey only has one question where an Integer is compared to an int. In the other cases the comparison is int vs. int. Only in the case of a comparison between an Integer and and Integer, which the survey didn't contain, must the details of auto-boxing be known (i.e. the auto-boxing caches).

A small teaser: one question was answered incorrectly by 60% of the respondents.
