Question
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.
