transient variable example

//A transient variable is a variable that may not be serialized

package Serialization;

import java.io.Serializable;

public class serializableClass implements Serializable
{

/**
*
*/
private static final long serialVersionUID = 1L;

String name;
int DOB;
int DOM;
/*If we don't want to pass the Year Of Birth of any one, then we simply make that variable as "transient"*/
transient int year;
public serializableClass(String name,int dob,int year)
{
this.name = name;
this.DOB = dob;
this.year = year;
}
public void showWish()
{
System.out.print("Good Morning!");
}
public String toString()
{
showWish();
return "Mr."+name+". Your date of birth is "+DOB+"/"+DOM+"/"+year;
}
}

package Serialization;

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;

public class mainClass {
public static void main(String args[]) {

serializableClass srl = new serializableClass("Arun", 14, 1984);

oos.writeObject(srl);

oos.close();

} catch (Exception e) {

Output =>
Start of serialization ******************************
Good Morning!Mr.Arun. Your date of birth is 14/2/1984
End of serialization *************************


Start of deserialization ************************
Good Morning!Mr.Arun. Your date of birth is 14/2/0
