What does serialization mean in java?

[Honorata]

Hi All,

I have lots of confusion in the serialization concept of the java.I want to share this problem with you to sort-out the solution over this.

Is this something like encoding? or what?

Please anybody let me know what is serialization in the java?

Your help will be greatly appreciated...

Hi friend,

The procedure of storing an state of the object to a byte sequence along with rebuilding of those bytes in a live object during some future time is called as "serialization in java". The API serialization gives a standard way to the java developers for handling serialization of the object.

Please refer the serialization program:

import java.io.Serializable;
import java.util.Calendar;
import java.util.Date;

public class PersistentTime implements Serializable
{
private Date time;

public PersistentTime()
{
time = Calendar.getInstance().getTime();
}

public Date getTime()
{
return time;
}
}

Hi,

I have sound knowledge about the java programming but unfortunately I am not deeply aware about the java serialization. Please see something below can help you :

import java.io.*;

public class SerializingObject_demo{

public static void main(String[] args) throws IOException{
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Please enter name of the File : ");

String file = in.readLine();

System.out.print("Enter the extention : ");

String ext = in.readLine();

String filename = file + "." + ext;

File f1 = new File(filename);

try{

ObjectOutput ObjOut = new ObjectOutputStream(new FileOutputStream(f));

ObjOut.writeObject(f1);

ObjOut.close();

System.out.println("Serializing completed successfully.");

}

catch(IOException e){

System.out.println(e.getMessage());

}

}

}

*. Serialization process comprises the storing the object's current state to a stream as well as restoring an object from that particular stream.

*. Serialization in java extends the core Java classes of Output/Input
by using support of objects.

*. In java serialization is used in light-weight persistence & to communicate through RMI(Remote Method
Invocation () OR sockets.
