Are static variables serialized in Serialization process

Question

I\'m stumbled upon understanding java serialization. I have read in many documents and books that static and transient variables cannot be serialized in Java. We declare a

Answer 1

serialVersionUID is a special static variable used by the serialization and deserialization process, to verify that a local class is compatible with the class used to serialize an object. It's not just a static variable as others, which are definitely not serialized.

When an object of a class is first serialized, a class descriptor containing among other things the class name and serial version UID is written to the stream. When this is deserialized, the JVM checks if the serial version UID read from the stream is the same as the one of the local class. If they're not, it doesn't even try to deserialize the object, because it knows the classes are incompatible.
