public interface DataSerializable
DataSerializable is a serialization method alternative to standard Java serialization. DataSerializable is very similar to Externalizable and relies on reflection to create instances using class names.

Conforming classes must provide a no-arguments constructor to facilitate the creation of their instances during the deserialization. Anonymous, local and non-static member classes can't satisfy this requirement since their constructors are always accepting an instance of the enclosing class as an implicit argument, therefore they must be avoided.
