What is Externalizable or Java externalization or Custom Serialization in Java?

Welcome to this in-depth Java tutorial where we explore Externalizable, also known as Java externalization, and custom serialization! In this video, we will dive into the concepts of Externalizable interface in Java, its benefits, and how it differs from the Serializable interface.

Java Serialization is a powerful feature that allows objects to be converted into a byte stream for storage, transmission, or distribution across different Java virtual machines. Externalizable provides a way to customize this serialization process beyond what Serializable offers, giving developers more control over how objects are serialized and deserialized.

In this tutorial, you'll learn:
- The basics of Java Serialization and its purpose
- What Externalizable interface is and when to use it
- Step-by-step guide to implementing Externalizable in your Java classes
- Differences between Serializable and Externalizable
- Real-world examples demonstrating custom serialization with Externalizable
- Best practices to follow when using Externalizable for optimal performance

Whether you're a beginner exploring Java serialization or an experienced developer looking to enhance your understanding of custom serialization techniques, this tutorial will provide you with valuable insights and practical knowledge.

good effort.i have doubt we can use transient key word before the field for the same in serialization process .then what is the difference.
