For serializable objects, sufficient information is kept to restore those objects even if a different (but compatible) version of the implementation of the class is present. The Serializable interface is defined to identify classes which implement the serializable protocol: package java.io; public interface Serializable {};

Aug 3, 2022 · Serialization in Java. Serialization in Java allows us to convert an Object to stream that we can send over the network or save it as file or store in DB for later usage.

Quá trình chuyển đổi chuỗi byte thành đối tượng gọi là ... Java serialization enables writing Java objects to the file systems for permanent storage or on the network to transfer to other applications. Serialization in Java is achieved with Serializable interface. Java Serializable interface guarantees the ability to serialize the objects. This interface recommends we use serialVersionUID also.

If a serializable class does not explicitly declare a serialVersionUID, then the serialization runtime will calculate a default serialVersionUID value for that class based on various aspects of the class, as described in the Java Object Serialization Specification. This specification defines the serialVersionUID of an enum type to be 0L.
