Question

How are the constructors called during serialization and deserialization

1. When there is one class implementing serializable?
2. When there is parent/child

Answer 1

The deserialization process does not use the object's constructor - the object is instantiated without a constructor and initialized using the serialized instance data. The only requirement on the constructor for a class that implements Serializable is that the first non-serializable superclass in its inheritence hierarchy must have a no-argument constructor.
