Narrowing is not safe because the classes will become more and more specific thus giving rise to more and more doubts. Generalization Generalization uses a "is-a" relationship from a specialization to the generalization class. For serializing the object, we call the writeObject() method of ObjectOutputStream class, and for deserialization we call the readObject() method of ObjectInputStream class. Generalization. Representing hierarchical relationships in a relational database is tricky. Database management system is software that is used to manage the database.

Generalization. The concept of generalization (specialization) is associated with special types of entities known as superclasses and subclasses, and the process of attribute inheritance. For example, if we say Car is a Vehicle, there will be no objection. If a class has a reference to another class, all the references must be Serializable otherwise serialization process will not be performed. Hence, this is called narrowing or down-casting.
