Specialization and generalization is the subclass and superclass hierarchy mechanism in a relational database akin to the concept of inheritance in Java. Types of Inheritance in Java. In encapsulation, the variables of a class will be hidden from other classes, and can be accessed only through the methods of their current class. Basic yet prompts complication sometimes as a result of its properties and behavior not. In the last textfield, you can write the class name of java program. If any object is not serialiizable, serialization will be failed. It depicts the relationship between objects, such as a teacher, can be associated with multiple teachers. Certain attributes of the superclass may apply to some but not all entities of the superclass. Generalization - Generalization is the process of extracting common properties from a set of entities and create a generalized entity from it. Generalization Generalization is like a bottom-up approach in which two or more entities of lower level combine to form a higher level entity if they have some attributes in common.
