Edit Question
Title
Body
I have the following kind of situation: Set<Element> set = getSetFromSomewhere(); if (set.size() == 1) { // return the only element } else { throw new Exception("Something is not right.."); } Assuming I cannot change the return type of getSetFromSomewhere() , is there a better or more correct way to return the only element in the set than Iterating over the set and returning immediately Creating a list from the set and calling .get(0)
