Principles, Benefits &#038; Examples Explained"},"content":{"rendered":"<p><span style=\"font-weight: 400;\">A computer programming model that organises software design around data or objects rather than functions and logic is known as Object oriented programming- abbreviated as OOP. Well, an object can be defined as a data field that has unique attributes and behaviour.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Object-oriented programming focuses on the objects that developers would want to manipulate without applying logic. Honestly, this programming approach is suited for software that is large, complex or requires frequent updates and maintenance.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Thus, it is majorly used in manufacturing and design and mobile applications. For example, Object Oriented Programming can be used for manufacturing system simulation software.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The object oriented programming method is beneficial for collaborative development, where actually the projects are divided based on the groups. Some of the additional benefits of object oriented programming include:\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Code Reusability\u00a0<\/span><\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Scalability\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Efficiency<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">The very first step in object oriented programming is to collect all the objects a programmer desires to manipulate and identify how they are related to each other. Well, this is popularly known as data modeling.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For example of object can be from a physical entity- like a human being who is associated by properties like name, and address to small computer games like widgets.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A once-known object is assigned to a class of objects. The class of objects indicates the kind of data held and all logic sequences capable of manipulating it. There exist different distinct logic sequences in each method. Objects are able to communicate through a well-defined interface referred to as a message.<\/span><\/p>\n<h2><b>What are the basics of object-oriented programming?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Here are the 4 basics of object-oriented programming:\u00a0<\/span><\/p>\n<table>\n<tbody>\n<tr>\n<td><span style=\"font-weight: 400;\">Classes<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Objects<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Methods\u00a0<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Attributes\u00a0<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Classes-\u00a0 A user-defined data type that precisely acts as a blueprint for each object, attribute and method.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Objects- Instances of a class created specifically to define the data. This can be real-world objects or some abstract entity. Initially, when the class is defined the description is the only object that is defined.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Methods- These are the functions that objects can perform. It is defined inside a class and it describes the behaviour of an object. Each method contained in class definitions starts with a reference to an object. Additionally, instance methods are the subroutines contained in an object. Methods are used by programmers for reusability or to keep functionality encapsulated inside one object at a time.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Attributes- It represents the state of an object. It also means that these are the characteristics that distinguish classes. Data is stored in the attributes field in the object. Class attributes belong to the class itself and are also defined by the class template.\u00a0<\/span><\/li>\n<\/ul>\n<h2><b>What are the main principles of OOP?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Object-oriented programming is based on the following principles:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Encapsulation:<\/b><span style=\"font-weight: 400;\"> This principle of OOP states that all the important information is stored inside an object and only selected information is revealed. This implementation and state of individual objects is privately held inside a defined class. In this case, other objects do not have access or authority to make changes in this class. And since they do not have access to authority to make changes they are only able to call a list of public functions or methods. This feature of data hiding provides greater program security and avoids unintended data corruption.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Abstraction: <\/b><span style=\"font-weight: 400;\">The internal mechanisms are shown by objects only in case of use for other objects. The unnecessary implementation code will be hidden in this way. The derived class can have its functionality extended. This concept can help developers more easily make additional changes or additions over time.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Inheritance:<\/b><span style=\"font-weight: 400;\"> Another principle of OOP is Inheritance. This is classes can inherit code and properties from other classes. Relationships and subclasses between objects can be assigned, enabling developers to reuse common logic, while still maintaining a unique hierarchy. Inheritance forces more thorough data analysis reduces development time and ensures a higher level of accuracy.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Polymorphism: <\/b><span style=\"font-weight: 400;\">Objects are built to share behaviours, and they can be in more than one form. The program determines which meaning or usage is required for each execution of that object from a parent class reducing the need to duplicate codes. A child class then gets created, which expands the functionality of the parent class. It allows different types of objects to pass through the same interface.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Syntax:<\/b><span style=\"font-weight: 400;\"> It is nothing but a set of rules that describe the arrangement of words and punctuation in a programming language. Syntax is also one of the important principles of OOP.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Coupling<\/b><span style=\"font-weight: 400;\">: This describes the extent to which different software elements are interrelated. For instance, given that a class has attributes change, then another coupled class also changes.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Association<\/b><span style=\"font-weight: 400;\">: This is the link between one or more classes. These associations can be one-to-one, many-to-many, one-to-many or many-to-one.<\/span><\/li>\n<\/ul>\n<h2><b>What are the benefits of OOP?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Benefits of OOP include the following:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Modularity- Objects can be encapsulated as self-contained, thus helping in troubleshooting and collaborative development.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Reusability- Code can be reused via inheritance, thus a group of people do not need to write the same code several times.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Productivity- Programmers can assemble new programs fast through many libraries and reusable code<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Independent- Easily upgradable and scalable. Programmers can implement system functionalities independently.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Interface descriptions- Due to message passing techniques, external systems description is straightforward.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Security-\u00a0 Because of encapsulation and abstraction, complicated codes are masked; it will be easy to maintain a software application, as internet protocols will be masked from being disturbed.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Flexibility- There is an adaption capability from polymorphism which would result in one function accepting a single class into its placement while passing objects through one interface.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Code maintenance- A system can be updated and maintained without requiring a great deal of adjustment.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Low cost- Other benefits of OOP, including its maintenance and reusability, is it reduces the development costs.<\/span><\/li>\n<\/ul>\n<h2><b>What are examples of object oriented programming languages?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">While Simula is the first object oriented programming language to be credited, many other programming languages are used with OOP today. But some programming languages go well with OOP than others. For instance, programming languages that are considered pure OOP languages treat everything as objects. Other programming languages are designed mainly for OOP but with some procedural processes included. Some of the most popular programming languages are designed for, or with, OOP in mind.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For example, the following are some of the very popular pure OOPs languages:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Ruby<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Scala<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">JADE<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Emerald<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Programming languages whose design is primarily based on OOPs include:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Java<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Python<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">C++<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Other programming languages used with OOPs include:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Visual Basic.NET.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">PHP<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">JavaScript<\/span><\/li>\n<\/ul>\n<h3><b>FAQs<\/b><\/h3>\n<p><b>FAQ 1: What is the main advantage of using Object-Oriented Programming (OOP)?<\/b><b><br \/>\n<\/b><span style=\"font-weight: 400;\">The main advantage of OOP is its ability to enhance code reusability, scalability, and maintainability.
