It is the reverse operation of serialization. In the generalization stereotype, there are two types of constraints that are complete and incomplete to check if all the child objects are involved or not in the relationship. It shows how objects of two classes are associated with each other. The reason for creating such hierarchical relationship is that: Figure 2: Relationship between members of a subclass.

It can provide a clear and logical view of the process that manipulates data. The writeObject() method of ObjectOutputStream class provides the functionality to serialize the object. It is also used to organize the data in the form of a table, schema, views, and reports, etc. AWT and Swing are used in Java for creating standalone applications. Converting a subclass type into a superclass type is called Generalization because we are making the subclass to become more general and its scope is widening. Serializable is a marker interface (has no data member and method). In generalization, entities are combined to form a more generalized entity, i.e., subclasses are combined to make a superclass. Each class stores relevant data in one row and any irrelevant columns in the row are kept empty. Just wanted to refresh these terms and explain in simpler terms.
