What are 100 differences between Java Serialization vs Java Deserialization?

Serialization and deserialization are two fundamental processes in computer science used for data storage, communication, and object manipulation. Here are 100 differences between serialization and deserialization:

1. Serialization is the process of converting data or objects into a byte stream, while deserialization is the process of converting a byte stream back into data or objects.
2. Serialization is used for data persistence, network communication, and object sharing, while deserialization is used for data retrieval and object reconstruction.
3. Serialization transforms data or objects into a portable format that can be transmitted or stored, while deserialization restores the data or objects to their original form.
4. Serialization is often used to save data to disk or send it over a network, while deserialization is used to load data from disk or receive it over a network.
5. Serialization typically involves writing data to an output stream, while deserialization involves reading data from an input stream.
6. Serialization can handle complex data structures, object graphs, and recursive references, while deserialization reconstructs these structures and references during the process.
7. Serialization can include metadata about the serialized data or objects, such as class information and field names, while deserialization can interpret and utilize this metadata during the reconstruction.
8. Serialization can be used to transfer objects between different programming languages or platforms, while deserialization allows these objects to be used within the target environment.
9. Serialization can preserve the state of an object, including its instance variables and transient fields, while deserialization restores this state during the reconstruction.
