Chapter 11.7, Problem 11.7.1CP

Explanation of Solution

Object Oriented Programming:

  • The real world entities are called as object like pen, pencil, chair etc. The object oriented programming is a paradigm or methodology to design a program using objects and classes.
  • The Object Oriented Programming main aim is to implement real world entities that is classes, inheritance, abstraction, polymorphism and object.

Three pillars of Objected Oriented Programming:

The object oriented programming language consists of three pillars. They are:

  • Encapsulation
  • Inheritance
  • Polymorphism

Encapsulation:

  • One of the fundamental concept of OOP is encapsulation. In Java, the encapsulation is a mechanism of wrapping the variables and code acting on the methods together as a one unit.
  • The variables of a class will be hidden from another classes and it can be accessed only though the methods of their present class.
  • It is also called as “data hiding”.

Inheritance:

The derived classes do not inherit the constructor functions of the base classes.

  • Inheritance is the concept of inheriting the members and properties of a base class from the derived class...
