From I read online, it seems a good practice to create a serial version ID for a class.

My question is that in an application, do I have to create an unique ID for each class?

Or can I simply assign the following ID to each class in my application?

private static final long serialVersionUID = 1;

    • You only need a serial version ID for classes that will be serialized, i.e. mostly those that implement Serializable
    • The ID is per class, it’s not a problem if two classes have the same
    • It’s only necessary if there is a chance that serialized instances will be deserialized by a different version of the program. This is often not the case.
