Java provides a mechanism, called object serialization where an object can be represented as a sequence of bytes that includes the object's data as well as information about the object's type and the types of data stored in the object. After a serialized object has been written into a file, it can be read from the file and deserialized that is, the type information and bytes that represent the object and its data can be used to recreate the object in memory. Most impressive is that the entire process is JVM independent, meaning an object can be serialized on one platform and deserialized on an entirely different platform. Classes ObjectInputStream and ObjectOutputStream are high-level streams that contain the methods for serializing and deserializing an object. read less

Serialization in java is a mechanism of writing the state of an object into a byte stream. It is mainly used in Hibernate, RMI, JPA, EJB, JMS technologies. The reverse operation of serialization is called deserialization. The String class and all the wrapper classes implements java.io.Serializable interface by default. Example: import java.io.*; class Persist{ public static void main(String args[])throws Exception{ Student s1 =new Student(211,"ravi"); FileOutputStream fout=new FileOutputStream("f.txt"); ObjectOutputStream out=new ObjectOutputStream(fout); out.writeObject(s1); out.flush(); System.out.println("success"); } } read less

There are three primary reasons why objects are not serializable by default and must implement the Serializable interface to access Java's serialization mechanism. Firstly, not all objects capture useful semantics in a serialized state. For example, a Thread object is tied to the state of the current...

A Java object is serializable if its class or any of its superclasses implements either the java.io.Serializable interface or its subinterface, java.io.Externaliz...
