It creates an ObjectOutputStream that writes to the specified OutputStream. Donec vitae sapien ut libero venenatis faucibus. The generalization relationship occurs between two entities or objects, such that one entity is the parent, and the other one is the child. The ObjectOutputStream class is used to write primitive data types, and Java objects to an OutputStream. Observe that the classes have one common attribute (AccountNo) and one common operation (process). Then you can compile and execute it. protected: accessible within the package . Database management system is a software which is used to manage the database. In generalization, entities are combined to form a more generalized entity, i.e., subclasses are combined to make a superclass.

In UML modeling, the realization is a relationship between two objects, where the client (one model element) implements the responsibility specified by the supplier (another model element). The child inherits the functionality of its parent and can access as well as update it. In other word, we can say that a super class is a generalization of its subclass. With no one best approach, the mapping often requires a smart mix and match of patterns because they are not mutually exclusive. The composition relationship is represented by a straight line with a black diamond at one end. We are saving the state of the object in the file named f.txt.
