4. serialization forums.oracle.comyou can just declair it Serializable and it will work. However, if you ever change the class at all in the future, it will no longer be compatable with old version.

Serialization forums.oracle.comIf a serializable class does not explicitly declare a serialVersionUID, then the serialization runtime will calculate a default serialVersionUID value for that class based on various aspects of the class, as described in the Java(TM) Object Serialization Specification.
