Typecasting is one of the most important concepts which basically deals with the conversion of one data type to another datatype implicitly or explicitly. Common features can be methods, attributes and associations. 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. In Figure 4.27, the classes Piece of Cargo ( 2 ) partially share the same attributes situation Student! In Generalization lower level functions are combined to form higher level function which is called as entities. So, a mapping object-oriented hierarchy in a relational schema requires a different approach altogether. In this article, the concept of typecasting for objects is discussed.

For example: Now, the Serializable class will look like this: JavaTpoint offers too many high quality services. Association is a relation between two separate classes which establishes through their Objects. Generalization is the process of common features from two or more classes, and combining them into a generalized super class. : //javapapers.com/oops/association-aggregation-composition-abstraction-generalization-realization-dependency/ '' > What is an abstraction in coding, or delete data implements the object-oriented concept called or. protected: accessible within the package in which it is defined and in its subclass(es)(including subclasses declared outside the package) private: accessible only within the class in which it is defined. It can view the database from different viewpoints according to the requirements of the user. A gen/spec diagram is a refined form of a class diagram. This is because we are making the subclass to become more general so that its scope can be more widening. 1) public final Object readObject() throws IOException, ClassNotFoundException{}. It is a "belongs-to" type of association. Database management system is a software which is used to manage the database. For serializing the object, we call the writeObject() method of ObjectOutputStream class, and for deserialization we call the readObject() method of ObjectInputStream class.
