A comment on this question: http://programmers.stackexchange.com/questions/136900/calling-a-method-that-returns-a-boolean-value-inside-a-conditional-statement says that you should use !boolean instead of boolean == false when testing conditions. Why? To me boolean == false is much more natural in English and is more explicit. I apologise if this is just a matter of style, but I was wondering if there was some other reason for this preference of !boolean?
