Instead of writing a long list of instructions for the computer, you organize your code into small blocks called <strong>objects<\/strong>. Each object has its own data and its own set of actions it can perform.<\/div>\n<div>Think of it like this. Imagine a car. A car has properties \u2014 like its colour, its speed, and its fuel level. A car also has actions \u2014 like starting, stopping, and turning. In OOP, you can create a &#8220;Car&#8221; object in code that has all of these things.<\/div>\n<div>OOP is used in many popular programming languages like Python, Java, C++, and C#.<\/div>\n<\/div>\n<p><strong><em>Also Read:<\/em> <a href=\"https:\/\/us.greatassignmenthelp.com\/blog\/how-to-write-the-best-quality-programming-assignment\/\">Learn How to Write the Best Quality Programming Assignment<\/a><\/strong><\/p>\n<div>\n<h2 id=\"2-why-was-oop-created\"><span class=\"ez-toc-section\" id=\"Why_Was_OOP_Created\"><\/span>Why Was OOP Created?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div>\n<p>Before OOP, programmers used something called <strong>procedural programming<\/strong>. This meant writing code as a long sequence of steps. As programs got bigger and more complex, this became very hard to manage.<\/p>\n<p>OOP was created to solve this problem. It lets you break big programs into smaller, more manageable pieces. It also makes it easier to reuse code across different projects.<\/p>\n<\/div>\n<div>\n<h2 id=\"3-the-4-main-concepts-of-oop\"><span class=\"ez-toc-section\" id=\"The_4_Main_Concepts_of_OOP\"><\/span>The 4 Main Concepts of OOP<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div>\n<p>OOP is built on four ideas. These are sometimes called the **four pillars of OOP**.<\/p>\n<h3 id=\"4-1-encapsulation\">\u00a01. Encapsulation<\/h3>\n<p>Encapsulation means keeping the data inside an object safe from outside interference. The object controls what information it shares and what it keeps private.<\/p>\n<div><strong>Real life example:<\/strong>\u00a0Your bank account. You can see your balance and make deposits. But the bank&#8217;s internal system \u2014 the calculations, the checks, the security rules \u2014 are hidden from you.<\/div>\n<div><strong>Code example (Python):<\/strong><\/div>\n<div>&#8220;`python<\/div>\n<div>class BankAccount:<\/div>\n<div>\u00a0 \u00a0 def __init__(self, balance):<\/div>\n<div>\u00a0 \u00a0 \u00a0 \u00a0 self.__balance = balance \u00a0# private variable<\/div>\n<div>\u00a0 \u00a0 def get_balance(self):<\/div>\n<div>\u00a0 \u00a0 \u00a0 \u00a0 return self.__balance<\/div>\n<div>\u00a0 \u00a0 def deposit(self, amount):<\/div>\n<div>\u00a0 \u00a0 \u00a0 \u00a0 self.__balance += amount<\/div>\n<div>account = BankAccount(1000)<\/div>\n<div>account.deposit(500)<\/div>\n<div>print(account.get_balance()) \u00a0# Output: 1500<\/div>\n<div>&#8220;`<\/div>\n<div>In this example, `__balance` has two underscores. This makes it private. You cannot access it directly from outside the class.<\/div>\n<h3 id=\"5-2-inheritance\">2. Inheritance<\/h3>\n<p>Inheritance means one class can take on the properties and actions of another class. The class that passes on its properties is called the <strong>parent class<\/strong>. The class that receives them is called the <strong>child class<\/strong>.<\/p>\n<p><strong>Real life example:<\/strong>\u00a0All dogs are animals. So a Dog class can inherit everything from an Animal class \u2014 like the ability to breathe, eat, and sleep \u2014 and then add its own behaviour, like bark.<\/p>\n<div><strong>Code example (Python):<\/strong><\/div>\n<div>&#8220;`python<\/div>\n<div>class Animal:<\/div>\n<div>\u00a0 \u00a0 def breathe(self):<\/div>\n<div>\u00a0 \u00a0 \u00a0 \u00a0 print(&#8220;Breathing&#8230;&#8221;)<\/div>\n<div>class Dog(Animal):<\/div>\n<div>\u00a0 \u00a0 def bark(self):<\/div>\n<div>\u00a0 \u00a0 \u00a0 \u00a0 print(&#8220;Woof!&#8221;)<\/div>\n<div>my_dog = Dog()<\/div>\n<div>my_dog.breathe() \u00a0# Output: Breathing&#8230;<\/div>\n<div>my_dog.bark() \u00a0 \u00a0 # Output: Woof!<\/div>\n<div>&#8220;`<\/div>\n<div>The Dog class inherits `breathe()` from Animal and adds its own `bark()` method.<\/div>\n<h3 id=\"6-3-polymorphism\">3. Polymorphism<\/h3>\n<p>Polymorphism means &#8220;many forms.&#8221; In OOP, it means the same action can work differently depending on what object is doing it.<\/p>\n<p><strong>Real life example:<\/strong>\u00a0The word &#8220;speak&#8221; means something different for a human than for a dog. A human speaks in words. A dog barks. The action is the same name \u2014 speak \u2014 but the result is different.<\/p>\n<div><strong>Code example (Python):<\/strong><\/div>\n<div>&#8220;`python<\/div>\n<div>class Cat:<\/div>\n<div>\u00a0 \u00a0 def speak(self):<\/div>\n<div>\u00a0 \u00a0 \u00a0 \u00a0 print(&#8220;Meow!&#8221;)<\/div>\n<div>class Dog:<\/div>\n<div>\u00a0 \u00a0 def speak(self):<\/div>\n<div>\u00a0 \u00a0 \u00a0 \u00a0 print(&#8220;Woof!&#8221;)<\/div>\n<div>animals = [Cat(), Dog()]<\/div>\n<div>for animal in animals:<\/div>\n<div>\u00a0 \u00a0 animal.speak()<\/div>\n<div># Output:<\/div>\n<div># Meow!<\/div>\n<div># Woof!<\/div>\n<div><\/div>\n<p>Both Cat and Dog have a `speak()` method, but they behave differently.<\/p>\n<h3 id=\"7-4-abstraction\">4. Abstraction<\/h3>\n<p>Abstraction means hiding complicated details and showing only the simple, useful parts.<\/p>\n<div><strong>Real life example:<\/strong>\u00a0When you drive a car, you press the accelerator and the car moves faster. You don&#8217;t need to know how the engine works inside. The complexity is hidden from you.<\/div>\n<div><strong>Code example (Python):<\/strong><\/div>\n<div>&#8220;`python<\/div>\n<div>from abc import ABC, abstractmethod<\/div>\n<div>class Shape(ABC):<\/div>\n<div>\u00a0 \u00a0 @abstractmethod<\/div>\n<div>\u00a0 \u00a0 def area(self):<\/div>\n<div>\u00a0 \u00a0 \u00a0 \u00a0 pass<\/div>\n<div>class Circle(Shape):<\/div>\n<div>\u00a0 \u00a0 def __init__(self, radius):<\/div>\n<div>\u00a0 \u00a0 \u00a0 \u00a0 self.radius = radius<\/div>\n<div>\u00a0 \u00a0 def area(self):<\/div>\n<div>\u00a0 \u00a0 \u00a0 \u00a0 return 3.14 * self.radius ** 2<\/div>\n<div>c = Circle(5)<\/div>\n<div>print(c.area()) \u00a0# Output: 78.5<\/div>\n<div>&#8220;`<\/div>\n<div>The Shape class says &#8220;every shape must have an area method&#8221; but doesn&#8217;t say how. Each specific shape \u2014 like Circle \u2014 defines its own way of calculating area.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div><\/div>\n<div><strong>Also Read:<\/strong> <em><a href=\"https:\/\/us.greatassignmenthelp.com\/blog\/low-level-programming-language-examples\/\">Get to Know about Low-Level Programming Language Examples<\/a><\/em><\/div>\n<div>\n<div>\n<div>\n<div>\n<h2 id=\"8-classes-and-objects-explained\"><span class=\"ez-toc-section\" id=\"Classes_and_Objects_Explained\"><\/span>Classes and Objects Explained<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>You will hear these two words a lot in OOP.<\/p>\n<p>A <strong>class<\/strong>\u00a0is like a blueprint or a template.

These are user-defined data types. It typically serves as a blueprint or a template for objects, methods, and attributes.Inside a class, variables, constants, member functions, and other functionality can be defined. It generally integrates data and functions into a single unit. It does not use memory at runtime.Classes are not a data structure. It is a logical entity and is the best example of data binding. Remember, a class can exist in the absence of an object, but not the other way around.<\/p>\n<h3 id=\"20-objects\">Objects<\/h3>\n<p>Objects are class instances formed with specially designed data. In general, objects are real-world entities that contain unique attributes, properties, and behaviors. The description is the only object defined when the class is first formed.The object includes member functions and variables defined in the class. Most importantly, the objects occupy a certain space in the memory.<\/p>\n<h3 id=\"21-methods\">Methods<\/h3>\n<p>Methods are functions that define an object&#8217;s actions inside a class. A reference to an instance object is the first step in any method that is specified in class declarations. In addition, instance methods refer to the subroutines that are part of an object. Programmers employ methods to maintain functionality contained within a single object at a time or to allow for reusability.<\/p>\n<h3 id=\"22-attributes\">Attributes<\/h3>\n<p>In the class template, the attributes represent an object\u2019s state. Usually, the attributes field will contain data for objects. Furthermore, class attributes will have a strong relationship with the class itself.<\/p>\n<h2 id=\"23-key-principles-and-concepts-of-object-oriented-programming\"><span class=\"ez-toc-section\" id=\"Key_Principles_and_Concepts_of_Object-Oriented_Programming\"><\/span>Key Principles and Concepts of Object-Oriented Programming<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The object-oriented programming model works completely based on 4 main principles- Encapsulation, Abstraction, Inheritance, and Polymorphism.If you wish to use an object-oriented programming paradigm, then you must have a good comprehension of the concepts involved in it.<\/p>\n<p>Here, let us look in detail at the major OOP concepts and principles.<\/p>\n<h3 id=\"24-encapsulation\">Encapsulation<\/h3>\n<p>Encapsulation is the process of joining data and functions into a single entity. But, here, to access these data members, the scope of the member function needs to be set to &#8220;public&#8221; and the scope of the data members needs to be set to &#8220;private&#8221;.According to this principle, an object includes all relevant information, of which the external world can see only a small portion. Every object contains a private class that includes its state and implementation.<\/p>\n<p>Encapsulation guards against unauthorized usage and outside interference with data and services. As a result, security is also provided.<\/p>\n<h3 id=\"25-abstraction\">Abstraction<\/h3>\n<p>Abstraction is one of the essential concepts in object-oriented programming. It is the act of describing important features without providing supporting information.Typically, abstraction is a method that creates a completely new data type that is suitable for a certain application. It avoids unnecessary information and only displays the exact section that the user has requested. Abstraction is important because it prevents developers from doing the same task over and over again.<\/p>\n<h3 id=\"26-inheritance\">Inheritance<\/h3>\n<p>Inheritance is the process of obtaining properties. Especially, in OOP, an object passes properties to another object. Moreover, by establishing links and subclasses between objects, developers can reuse similar functionality and maintain a clear hierarchy. This feature of OOP accelerates development and improves accuracy by necessitating a more thorough analysis of the data.Typically, inheritance is the process of inheriting the properties of an existing parent class by a newly created child class. Hence, through inheritance, the parent-child relationship can be represented. Also, inheritance provides code reusability.<\/p>\n<h3 id=\"27-polymorphism\">Polymorphism<\/h3>\n<p>Polymorphism allows many classes to utilize the same method name. However, it also requires redefining methods for derived classes. There are two types of polymorphism: run-time polymorphism and compile-time polymorphism.In addition to having multiple forms, objects will have common behaviors. Particularly, to avoid writing redundant code, every time an object from a parent class is used, the program will identify which usage or meaning is needed.<\/p>\n<h3 id=\"28-coupling\">Coupling<\/h3>\n<p>The term &#8220;coupling&#8221; in object-oriented programming refers to the division of concerns. It implies that one object cannot directly alter another object&#8217;s state or behavior. Also, it describes the degree of connection between two objects. Tight coupling and loose coupling are the two different forms of coupling.Loosely connected objects are those that are unrelated to one another and do not directly alter the state of other objects. The code is more adaptable, malleable, and simpler to deal with when there is loose coupling.Tightly connected objects are those that are dependent on other items and can change the states of other objects. It establishes a situation in which altering the code of one thing necessitates altering the code of other objects. Since it is unable to divide the code into a tight coupling, code reuse may be challenging.<\/p>\n<h3 id=\"29-cohesion\">Cohesion<\/h3>\n<p>Cohesion in OOP describes how well the elements of a module fit together. It quantifies how strongly the module and data are related. In simple terms, coherence is the clarity of a module&#8217;s responsibilities. It is frequently contrasted with coupling.Typically, cohesion specifies how a single module or class is intended to be used. The object-oriented design improves as the module or class&#8217;s coherence increases.High and Low are the two types of cohesion. High cohesiveness has a connection with various necessary software properties, including robustness, dependability, and understandability. Low cohesiveness is related to undesirable characteristics such as being difficult to maintain, test, reuse, or even comprehend.<\/p>\n<h3 id=\"30-association\">Association<\/h3>\n<p>An association is a process that creates a relationship between two distinct classes with the use of their objects. In general, associations can be one-to-one, one-to-many, many-to-one, or many-to-many. An association is a link between two entities.Remember, an object can have one or more associations. Moreover, both unidirectional and bidirectional relationships are possible.<\/p>\n<h3 id=\"31-aggregation\">Aggregation<\/h3>\n<p>It is an advanced type of association in which each item has its lifecycle. However, ownership prohibits the child object from becoming a component of another parent object.Java aggregation displays a weak association between an entity and its contents. This demonstrates the relationship between a component and a whole, in which a part can live without the whole.When unconnected objects are united, they form a unique semantically weak connection type known as an aggregation.<\/p>\n<h3 id=\"32-composition\">Composition<\/h3>\n<p>Composition is a form of association that represents the relationship between a component and a whole, in which a part cannot exist without the whole. There are several ways to aggregate, one of which is composition.<\/p>\n<div><\/div>\n<div>\n<p>Since they don&#8217;t have a lifecycle, child objects all vanish together with the parent object. In any composition between two entities, one cannot exist without the other. As a result, the makeup of both entities is dependent upon the other.<\/p>\n<h3 id=\"33-modularity\">Modularity<\/h3>\n<p>Modular design is the split of a system into multiple functional sections (modules) that can be merged to form a larger application. Modularity and encapsulation have an intrinsic connection. Especially when transferring encapsulated abstractions into actual, physical modules, modularity is defined as high module cohesion and little inter-module interaction or coupling.<\/p>\n<h3 id=\"34-constructors\">Constructors<\/h3>\n<p>A constructor is a type of subroutine that plays a key role in generating an object. It initializes the new object for use. Also, it typically takes constructor arguments to initialize member variables. In OOP, a method is a process that has an association with a message and an object.The interface of an object consists of its state data and behavior, which specify how any of its countless customers can use it. A method is an object activity with consumer parameters.<\/p>\n<p><em><strong>Also Read: <a href=\"https:\/\/us.greatassignmenthelp.com\/blog\/sequel-programming-languages\/\">A Beginner\u2019s Guide to Sequel Programming Languages<\/a><\/strong><\/em><\/p>\n<h2 id=\"35-applications-of-object-oriented-programming\"><span class=\"ez-toc-section\" id=\"Applications_of_Object-Oriented_Programming\"><\/span>Applications of Object-Oriented Programming<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The following are some applications that use the OOP model.<\/p>\n<ul>\n<li>User-interface design, such as Windows<\/li>\n<li>Object-oriented database<\/li>\n<li>Computer graphics applications<\/li>\n<li>Real-time systems<\/li>\n<li>Simulation and modeling software<\/li>\n<li>Client-Server System<\/li>\n<li>CAD\/CAM Software<\/li>\n<li>Artificial Intelligence System<\/li>\n<li>Office automation system<\/li>\n<\/ul>\n<p><strong><em>Also Read:<\/em><a href=\"https:\/\/us.greatassignmenthelp.com\/blog\/most-popular-programming-languages\/\">10 Most Popular Programming Languages 2024<\/a><\/strong><\/p>\n<\/div>\n<div><\/div>\n<div>\n<div>\n<h2 id=\"36-faqs\"><span class=\"ez-toc-section\" id=\"FAQs\"><\/span>FAQs<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div>\n<h3 id=\"37-q-what-does-oop-stand-for\">Q: What does OOP stand for?<\/h3>\n<p>OOP stands for Object-Oriented Programming.
