A modern programming language that makes developers happier.

kotlinlang

does kotlin serialziation uses `Serializable`  of java ?
why I am asking this question, actually we need to store the some serialized data in local/Room DB
With Java's Serializable, problem is if we make any changes to the class implementing Serializable,. Its `serialVersionUID`  gets changed, which causes the problem in deserializing

No, kotlinx.serialization is for converting Kotlin objects into standard structured representations, like JSON or Protobuf. Java's `Serializable` is an internal format that is only useful within Java, and kotlinx.serialization has no interop or compatibility with it.

Note that you can have a class be "serializable" with _both_ Kotlinx.serialization, and also by the Java interface.

You really shouldn't be using Java `Serializable` for any reason other than marshalling data around your application. Because of its `serialVersionUID` and the fact that the serialized representation is so closely linked with the Class binary, it's not really meant to persist serialized state over time.

In contrast, the standard formats like JSON are very-much designed to be parsed at a later date, with changes to the class/schema that originally produced it, or even to pass into other programming languages.

For `SerialVersionUID` I just got to know this Today
