I think I may have found an error in the cow roundup. I forgot the question number though, so I can't look it up again. The question was if 2 Integers with value 5 are '=='. The correct answer is yes. Shorts and Integers with a value between -128 and 127 are considered '==', even if they are different objects. With another value they are not '==', but are 'equals'. (Not good English, but I think you know what I mean). Can someone please confirm if that question was incorrect?
