serializing an object

[dmjpro]

this is my code .....

import java.io.*;

class TestSerializeClass implements Serializable
{
public TestSerializeClass()
{
System.out.println("Debasis no argument constructor");
}
private void writeObject(ObjectOutputStream out)
{
System.out.println("Debasis write Object");
}
private void readObject(ObjectInputStream in)
{
System.out.println("Debasis read Object");
}
}

class TestSerialize
{
public static void main(String args[])
{
TestSerializeClass t = new TestSerializeClass();
}
}

when those above two private methods will be called and by whome ...


actually i don't understand why the serialization of an object is necessary ...

plz help me out ....

thanx in advance

Serialization involves saving the current state of an object to a stream and restoring an equivalent object from that stream. For example, saving an object to a file and reading it back later or transmitting an object over a network connection from a client to server, etc. Have a read of these tutorials

Hello,

If you are trying to call the two methods [viz,writeObject() and readObject() ] declared in class- 'TestSerializeClass' from within the class- 'TestSerialize' you will get an error, can you think why?

Hint: Look at the access modifiers of those methods.

[hirak1984]

we serialize any object to store it somewhere in the hard disk,and remove fron main memory.

it is important for large programs because it reduces the overheads of main memorythus the application speed increases.
this is the most basic idea,I can give.
the details is quite complex.
