Serialization

[Ritu Kapoor]

We implement readObject(ObjectInputStream)/writeObject(ObjectOutputStream) in a class implementing Serializable interface to customize the serialization process. Now my question is:

1) Why are we supposed to provide implementation of these methods, when the Serializable interface is a marker interface. Where these methods come from ? Why the method signature should be like this.

2) When should we use serialization and Externalizable interface, when the customization of serialization can be achieved by either of them.
