Sorted by: 38. The Serial Version ID is used when serializing and deserializing an object. Java recognizes if the bytes you want to deserialize match the local class version. If not it will throw an exception. This is important when doing RMI or persisting object structures. There's a very good description about serializing in the javadoc of ...

Deserialization is the reverse process – converting a stream of bytes into an object in memory. During serialization, the java runtime associates a version number with each serializable class.It means that the class can be serialized. This means that it can be converted into an stream of 0's and 1's and be sent to other service, like a webservice or and ORM (hibernate) or whatever. Then this service knows how store the stream.
