so that when the internals of a class change the vm knows whether it can serialize/deserialize an object based on the version of the class it has

thats used mainly to identify or distinguish the class versions!
serialization is given to a class to uniquely identify it during
serialization and deserialization. It is required so that the class will
be compatible with different version of jvm. You can set a random number
as serailVersionUID.
