20. Serialization and Deserialization
Serialization and Deserialization are critical processes in Java that facilitate the conversion of objects into byte streams for storage and transmission, along with their reconstruction back into objects. Java provides built-in support for these concepts through the Serializable and Externalizable interfaces, enabling efficient object management in distributed systems. Key techniques such as handling transient fields and managing serialVersionUID are emphasized for robust application design.

What we have learnt
- Serialization converts objects into byte streams for storage or transmission.
- Deserialization reconstructs objects from byte streams.
- The transient keyword prevents certain fields from being serialized.
Key Concepts
- -- Serialization
- The process of converting an object into a byte stream.

- A keyword used to indicate that a field should not be serialized.
- -- serialVersionUID
- A unique identifier for a serialized class to maintain version control.
- -- Externalizable
- An interface that allows custom serialization logic to be defined.
