How will you override default serialization mechanism in java..

Answer / sharmila

Serializable is a marker interface. But you may wish to
control on how an object is serialized instead of using the
default mechanism. In such case add implementations of the
readObject() and/or writeObject() methods to the class being
serialized and override default serialization mechanism.

Also, instead of using Serializable interface,
Externalizable interface can be used

you can inplements the Serialization interface for those
class you want to serailize
its marker interface its haven't any behaviour
but it indiacte that particular class is serializable
you can read and write particular object to convert in a
byte.
