Arrays are “special” in Java – they don’t implement any interfaces, which means they can’t implement the collection interfaces. They’re collections in “natural language” terms, and you can use the enhanced for loop over them – but if you want to use an array within the collection API, you’ll need something like
Arrays.asListwhich wraps an array with theList<T>interface. (The result is only a view on the array – changes to the array are visible through the list, and vice versa.)(This is in contrast to .NET, where
T[]implementsIList<T>etc.)
