No-arg constructor and Serialization/Externalization

[Vijay Chouhan]

Hello All,

Happy New Year to everyone. I am not sure if it has been answered before in this forum.

The serialization mechanism does not work if the first non-serializable superclass does not have a no-args constructor. Probably because without it, the JVM has no way of creating an object while deserializing.

However it works fine if you are using Externalization. Could someone throw some light on why so?

I hope my question makes sense.
