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.

    Deserialization

    Deserialization is the process of reconstructing an object from its serialized byte stream, allowing for the retrieval of data that was previously saved or transferred.

    Learning Practice

  • 20.5

    The Keyword Transient

    The transient keyword in Java is used to indicate that certain fields should not be serialized.

    Learning Practice

  • 20.6

    Serialversionuid

    The serialVersionUID is a unique version identifier essential for ensuring compatibility between serialized objects and their corresponding classes during deserialization.
