What is the purpose of the serialVersionUID field and how does it play a role during deserialization?
- It determines whether an object can be serialized or not
- It helps prevent security vulnerabilities in deserialization
- It is a randomly generated unique identifier
- It specifies the version of the class, ensuring compatibility during deserialization
The serialVersionUID field is used to specify the version of a class during serialization. It plays a crucial role during deserialization by ensuring compatibility. If the version of the class that was serialized differs from the version during deserialization, it can lead to InvalidClassException. This field helps maintain compatibility and avoid issues. The other options are not the primary purpose of serialVersionUID.
