Serialization with ObjectInputStream and ObjectOutputStream

      

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

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);
  }
}

class SerializeDemo {
  public static void main(String[] args) {
    Employee e = new Employee();
    e.name = "A";
    e.address = "B";
    e.SSN = 11111;
    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();
    }
  }
}

class DeserializeDemo {
  public static void main(String[] args) {
    Employee e = null;
    try {
      FileInputStream fileIn = new FileInputStream("employee.ser");
      ObjectInputStream in = new ObjectInputStream(fileIn);
      e = (Employee) in.readObject();
      in.close();
      fileIn.close();
    } catch (IOException i) {
      i.printStackTrace();
      return;
    } catch (ClassNotFoundException c) {
      System.out.println("Employee class not found");
      c.printStackTrace();
      return;
    }
    System.out.println("Name: " + e.name);
    System.out.println("Address: " + e.address);
