Serialization in Java with Example

Serialization converts state of an Java Object to a byte stream so that it can be transferred to other JVM over the network and can be reverted back into a copy of the object without losing it’s state and values.

This example shows how to Serialize a Java Object by implementing the Serializable interface.

Employee.java

public class Employee implements java.io.Serializable {
   public String name;
   public String address;
   public transient int SSN;
   public int number;

   public void mailCheck() {
      System.out.println("Mailing a check to " + name
                           + " " + address);
   }
}

public class Employee implements java.io.Serializable {

public String name;

public String address;

public transient int SSN;

public int number;

public void mailCheck() {

System.out.println("Mailing a check to " + name

+ " " + address);

}

SerializeDemo.java

import java.io.*;

public class SerializeDemo {
   public static void main(String [] args) {
      Employee e = new Employee();
      e.name = "Prasanna Sherekar";
      e.address = "Amravati, Maharashtra, India";
      e.SSN = 11122333;
      e.number = 101;
      try {
         FileOutputStream fileOut = new FileOutputStream("employee.ser");
         ObjectOutputStream out = new ObjectOutputStream(fileOut);
         out.writeObject(e);
         out.close();
          fileOut.close();
      } catch(IOException i) {
          i.printStackTrace();
      }
   }
}

import java.io.*;

public class SerializeDemo {

public static void main(String [] args) {

Employee e = new Employee();

e.name = "Prasanna Sherekar";

e.address = "Amravati, Maharashtra, India";

e.SSN = 11122333;

e.number = 101;

try {

FileOutputStream fileOut = new FileOutputStream("employee.ser");

ObjectOutputStream out = new ObjectOutputStream(fileOut);

out.writeObject(e);

out.close();

fileOut.close();

} catch(IOException i) {

i.printStackTrace();

}
