Long is a so-called primitive wrapper class. All primitive types in Java have their correspondig "wrapper" type, starting with a capital letter - they are simply classes which encapsulate the given primitive type as a field (and contain some additional helper methods). There can be various reasons for using them, e.g. to put them in collections, which can only contain Objects.
