How to do Serialization and Deserialization ?

Leave a Comment / CoreJava, Serialization / By SOMASEKHAR REDDY

n this tutorial, We’ll discuss about java’s java.io.Externalizable interface. The main goal of this interface is to provide custom serialization and deserialization.

package com.vidvaan.corejava.serilaization01.serilizable;

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

public class DeserializationExample {

	public static void main(String[] args) throws IOException, ClassNotFoundException {
		// Deserialization
		Employee deserialisedEmpObj = deserialize();
		System.out.println("After deserialization => " + deserialisedEmpObj.toString());
	}

	// Deserialization code
	private static Employee deserialize() throws IOException, ClassNotFoundException {
		try (FileInputStream fis = new FileInputStream("Employee.ser");
				ObjectInputStream ois = new ObjectInputStream(fis)) {
			return (Employee) ois.readObject();
		}
	}

}

package com.vidvaan.corejava.serilaization01.serilizable;

import java.io.FileInputStream;

import java.io.IOException;

import java.io.ObjectInputStream;

public class DeserializationExample {

public static void main(String[] args) throws IOException, ClassNotFoundException {

// Deserialization

Employee deserialisedEmpObj = deserialize();

System.out.println("After deserialization => " + deserialisedEmpObj.toString());

}

// Deserialization code

private static Employee deserialize() throws IOException, ClassNotFoundException {

try (FileInputStream fis = new FileInputStream("Employee.ser");

ObjectInputStream ois = new ObjectInputStream(fis)) {

return (Employee) ois.readObject();

}
