Chapter 20: Problem 8

How do regular inheritance, multiple inheritance, and selective inheritance differ?

Short Answer

Expert verified
Regular inheritance allows inheriting from one superclass, multiple inheritance allows inheriting from multiple superclasses, and selective inheritance (not a standard term) would involve choosing specific properties to inherit from multiple superclasses.

Step by step solution

01

Define Regular Inheritance

Regular Inheritance, also known as single inheritance, allows a class to inherit properties and behavior from a single superclass (parent class). An inherited class is called a subclass (child class). This means a class can only directly inherit from one other class.
02

Define Multiple Inheritance

Multiple Inheritance is a feature in which a class can inherit properties and behavior from more than one superclass (parent classes). It allows a subclass to inherit features from multiple parent classes.
03

Define Selective Inheritance

Selective Inheritance is not a standard term in Object-Oriented Programming. However, if it's interpreted in the context of multiple inheritance, it can be considered as a process where a class can choose which properties or behaviors a class wants to inherit from its multiple superclasses.
04

Contrasting Differences

Regular inheritance involves inheriting from one superclass, multiple inheritance involves inheriting from multiple superclasses, while selective inheritance involves choosing specific properties or behaviors to inherit from multiple superclasses. The choice depends on flexibility required in terms of inheriting properties and behaviors. Regular inheritance is less flexible whereas multiple inheritance is more so, but can become complex. 'Selective inheritance' provides an even more flexible approach where you need to have control over what to inherit from parent classes.
