Inheritance in Object Oriented Programming (Java)

Inheritance is one of the core principles of object-oriented programming (OOP), which help us derive a class from another class or a hierarchy of classes that share a set of attributes and methods. In other words, it is a relationship between a superclass (a more generalised class) and a subclass (a more specialised class), where the subclass inherits data and behavior from the superclass.

Method Overloading in OOPS (Java)

Java language has a feature called method overloading, which allows multiple methods within a class to have the same name with different argument lists. It is a type of polymorphism (the process by which we can perform a single task in various ways). To be more concise, overloading is an example of static polymorphism.

Introduction to Constructors in Java

In oops, we may want our object to get initialized with some specific properties, or we may need to do some operations every time an object is instantiated. To do such things, we use constructors. In simple words, a constructor is defined inside the class that contains the code to instantiate the class object.

Classes and Objets in Object Oriented Programming (OOP)

A class is a user-defined blueprint that describes what a specific kind of object will look like, but an object is an instance of a class, which contains data and methods working on that data. In simple words, classes and objects are the fundamental building blocks of Object-Oriented Programming (OOPS).

Abstraction in Object Oriented Programming (OOPS)

In OOPS, Abstraction exposes necessary functionality to external objects and hides implementation details. This helps programmers to use complex logic without understanding its implementation. In other words, Abstraction is a process of exposing relevant functionalities so that one needs to know what the code does, not how it does it.

Encapsulation in Object Oriented Programming (OOPS)

Encapsulation is one of the fundamental concepts in OOP that bundles data and associated methods that operate on that data into a single block called class. It is also a pathway for restricting direct access to some data and methods associated with a class (which leads to data hiding).

Object Oriented Programming (OOPS) Concepts in Java

Learning Object-Oriented Programming is essential for modern software development as it introduces many features such as Inheritance, Encapsulation, Abstraction, and Polymorphism. Besides reducing code complexity, the oops provide other advantages like code modularity, code reusability, code extensibility, data hiding, etc.

Object Oriented Programming (OOPS) Concepts in C++

Object-Oriented Programming binds together the data and the methods in the form of an object and selectively exposes the data to other objects. It primarily revolves around classes and objects, i.e., their definition, instantiation, relationship, communication, etc. It helps us to organize code and development processes for large-scale software.
