According to Sun, 3 billion devices run Java. A classifier implementing an interface identifies the objects that conform to the interface and any of its ancestors. It must be of the long type with static and final. Only objects that support the java.io.Serializable interface can be written to streams. Phasellus viverra nulla ut metus varius laoreet. Java Tutorial. Converting a super class type into a sub class type is called Specialization. The concept of generalization (specialization) is associated with special types of entities known as superclasses and subclasses, and the process of attribute inheritance. 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. "super" in Java is used to refer to methods, static and instance variables, constructors of an immediate parent class. Loosely speaking, a class which tells the main features but not the specific details. In UML, it can exist between two or more classes. Simple yet provokes confusion at times due to its unmatched organization between relational as.
