Serialization

Hi there!
I wonder what exactly happens to a static variable that has been declared and initialized in a class that implements Serializable and when that class is passed to an output stream with the writeObject() method as follows:


Output: 10 0 10

As static variables would not be serialized, should'nt s2.z return 0? What exactly is happening here. Can someone explain?

Run B.class after runing A.class. You will get s2.z=9. because z is static member and will initialized when the class is loaded (first time).

don't get confused by transient.
after being deserialized, transient variable is reset to its default value, while static variable keeps its original value
 
It is sorta covered in the JavaRanch Style Guide.
