Chapter 6_Classification, Generalization, and Specialization

Classification

is the process of grouping objects together based on common characteristics.

In Java, this is achieved through the use of classes and interfaces.

Classes, interfaces

_____ and _____ can be used to classify objects based on their attributes and behaviors.

Interface

is a collection of abstract methods and constants that can be implemented by a class

Interface

defines a set of methods that a class implementing that interface must provide.

methods in an interface

do not have any implementation, but only the method signatures are defined.

inheritance

Hierarchical relationship of classesi is created using _____.

child class

can inherit properties and methods from a parent class, and can also add its own properties and methods.

hierarchy of classes

This creates a _____, where each child class can inherit from its parent class, and can also be inherited by other child classes.

Generalization

is the process of creating a more general class from a more specific class.

Generalization

This allows you to create a hierarchy of classes that share common properties and behavior.

Specialization

is the opposite of generalization

Specialization

it involves creating a more specific class from a more general class.

Specialization

This allows you to add additional properties and behavior to a more specific class without affecting the more general class.

Specialization

is the act of capturing differences among objects in a class and creating new distinct subclasses with the differences.

Specialization

In this way, we are specializing information about objects of the superclass into subclasses.

Classification

categorizing objects into a class.

Classification

A subclass is a specialized class of a superclass, and a superclass is a generalized class of a subclass.

Generalization

the act of capturing similarities between classes and defining the similarities in a new generalized class

Generalization

the classes then become subclasses of the generalized class.

Specialization

the act of capturing differences among objects in a class and creating new distinct subclasses with the differences.
