Examples of standalone application are Media player, antivirus, etc. Student and Employee are subclasses, because they have different attributes and methods. When a superclass reference (referring to superclass object) is narrowed, then using that reference we can access neither methods of subclass nor methods of superclass. The implementation of its properties and behavior is not a concern of the clients. It can reduce the complex relationship between data. Generalization uses a "is-a" relationship from a specialization to the generalization class. We must have to implement the Serializable interface for serializing the object. There are two types of relationships or associations in Java used to reuse a code and reduce duplicity from one class to another. How to Convert java.util.Date to java.sql.Date in Java?
