In the above example, two separate classes Bus and Passenger, are associated through their Objects inside the class Demo. In this way, we can establish the relationship between two different classes by using the concept of association. A bus can have many passengers, So it is a one-to-many...
Example of Inheritance// C++ program to demonstrate example of // simple inheritance #include <iostream> using namespace std; // Base Class class A { public: void Afun(void); }; // Function definiion void A::Afun(void) { cout << "I'm the body of Afun()..." << endl; } //...
Abstraction is the concept of hiding the internal details and describing things in simple terms. For example, a method that adds two integers. The internal processing of the method is hidden from the outer world. There are many ways to achieve abstraction in object-oriented programmings, such a...
Let’s understand the concept of encapsulation and access modifiers with the help of a simple example: #include <iostream>using namespace std;class AccessExample {public: // Public member variable int publicVar; // Public member function void publicFunction() { cout << "Public Function" << ...
Video #2: Concept of Inheritance in Python Video #3: Overloading, Overriding & Data Hiding in Python Classes and Objects Python is an object-oriented programming language where programming stresses more on objects. Almost everything in Python is objects. Classes Class in Python is a collectio...
A very simple example to explain the concept is to make the member variables of a class private and providing public getter and setter methods. Java provides four types of access level modifiers: public, protected, no modifier and private. What is the difference between Abstraction and ...
Example of encapsulation: A class in java is a simplest example of encapsulation. It keeps the data(variables) and behavior(methods) of an entity together. A class also restricts access to these data and behavior through the use of access specifiers. The concept of keeping instance variables ...

It supports the concept of hierarchical classification. For example: Car is a four wheeler vehicle so assume that we have a class FourWheeler and a sub class of it namedCar. Here Car acquires the properties of a classFourWheeler. Other classifications could be a jeep, tempo, van etc. Four...
