Serialization Concept In Java with Composition

Question

If an object is going to be serialized will it be possible to serialize its data member(which are also objects that is composition).
If yes then in which order the state of those objects will be retrieved?

Answer 1

If they are also Serializable then, yes otherwise you'll get a NotSerializableException. If you explicitly want to not serialize a member object then declare it as transient.

Regarding the order, I don't get what you mean by that. If you read a serialized object you'll get it in the exact same state it had at serialization.
