Serialization and deserialization are processes in Java that allow you to convert objects into a format that can be easily stored, transmitted, or reconstructed. These processes are particularly useful when you need to persist objects to files, send them over a network, or store them in a database. Here’s an explanation of each:

Serialization:

  • Serialization is the process of converting an object’s state (i.e., its data members) into a byte stream.
  • The resulting byte stream can be saved to a file, sent over a network, or stored in some other way.
  • In Java, you can make a class serializable by implementing the Serializable interface. This interface serves as a marker, indicating that an object of the class can be serialized.
  • Serialization is typically used for data persistence, caching, and network communication.
  • Example:
package com.tipsontech.demo;

import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectOutputStream;
import java.io.Serializable;

//A class that implements Serializable
class Person implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
private String name;
private int age;

public Person(String name, int age) {
this.name = name…
