Question

How do you use subclassing to design simple class hierarchies that allow code to be reused for distinct subclasses? (250 own words)

Answer 1

what is subclass:

classes can be derived from other classes. The derived class is called a subclass.

The class from which it's derived is called the superclass.

The object oriented paradigm supports code reuse through inheritance. classes exist in a object oriented language in a class heirarchy.

A class can be declared as a subclass of another class,which is called the parent class.which is called as parent class or super class.

inheritance comes into two varieties:single inheritance and multiple inheritance.

in single inheritance the class hierarchy from a tree rooted in the most general class.

Single inheritance enables a derived class to inherit properties and behavior from a single parent class. It allows a derived class to inherit the properties and behavior of a base class, thus enabling code reusability as well as adding new features to the existing code.

in multiple inheritance : which allows class to be a subclass of one or more superclasses.

Multiple Inheritance is a feature of object oriented concept, where a class can inherit properties of more than one parent class. The problem occurs when there exist methods with same signature in both the super classes and subclass. On calling the method, the compiler cannot determine which class method to be called and even on calling which class method gets the priority.

if you have any doubts ask me.... thank you
