What Do you Mean By Object Serialization in java...

Answer / nowsheen tariq

Serialization is a process of writing the state of the
object in a stream. The state of the object (information
available in the object)will be held in the instance
variable (not in the static variables)

There are various streams like
ByteArrayOutputStream, FileOutputStream,SocketOutputStream
all these streams can be used to store data to various
destinations like memory,file and someother program.

writeObject() method is for carryout the operation of
serialization.

Answer / ritesh prabhu

Object Serialization extends the core Java Input/Output
classes with support for objects. Object Serialization
supports the encoding of objects, and the objects reachable
from them, into a stream of bytes; and it supports the
complementary reconstruction of the object graph from the
stream. Serialization is used for lightweight persistence
and for communication via sockets or Remote Method
Invocation (RMI). The default encoding of objects protects
private and transient data, and supports the evolution of
the classes. A class may implement its own external encoding
and is then solely responsible for the external format.

Serialization now includes an API that allows the serialized
data of an object to be specified independently of the
fields of the class and allows those serialized data fields
to be written to and read from the stream using the existing
protocol to ensure compatiblity with the default writing and
reading mechanisms.
