Understanding Serialization in Java: A Beginner’s Guide

Serialization is an important concept in Java, especially when you need to save the state of objects or transfer them over a network. In this tutorial, we’ll discuss how serialization and deserialization work in Java using a simple Car class. The process of serialization allows you to save the state of an object to a file, while deserialization allows you to read that object back into memory. Here, we will explore the steps of serializing and deserializing an Car object.

We begin with a Car class, which implements the Serializable interface. This is essential because Java needs to know that the objects of this class can be converted to a byte stream and saved to a file.

import java.io.*;

// Simple Car class implementing Serializable
class Car implements Serializable {
    String make;
    int year;
    Car(String make, int year) {
        this.make = make;
        this.year = year;
    }
}
public class CarSerializableExample {
    public static void main(String[] args) throws Exception {
        // Writing the object (Serialization)
        ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream("car.txt"));
        Car car1 = new Car("Toyota", 2021);
        out.writeObject(car1);
        out.close();
        
        // Reading the…
