Chapter 14.5, Problem 14.22CP

Program Plan Intro

Subclass:

• One class is derived from another class. The subclass is the derived class, which means the subclass contains more information when compared with the superclass.
• The subclass may not use all the methods of the superclass all the time. It uses only required methods.

Superclass:

• The superclass is the base class or a parent class which is used to derive a new class.
• The methods, functions and variables in the subclass are not used by the superclass.

Example:

Consider the example of superclass and subclass which is given below:

class Employee

{

//definition of superclass

}

class Manager extends Employee

{

//definition of subclass

}

Here, “Employee” is the superclass and “Manager” is subclass, which is extended from the superclass.
