why we use oops concepts what is its advantage

Security is the first main advantage of OOP, the data and functions are combined together in the form of class. We can also use a coding scheme to represent the values of a data item. Object-oriented programming (OOP) is a method of structuring a program by bundling related properties and behaviors into individual objects.In this tutorial, you’ll learn the basics of object-oriented programming in Python. Major OOPs Concepts :----- * Objects * Classes * Data Abstraction and Encapsulation * Inheritance * PolymorphismOOPs has the following advantages over conventional approaches: 1-->OOP provides a clear modular structure for programs which makes it good for defining abstract datatypes where implementation details are hidden and the unit has a clearly defined interface. The first OOPL was Simula, a simulation creation tool developed in 1960. Useful in customer retention and long-term relationships. OOP has key characteristics, encapsulation, inheritance, and polymorphism. It’s interacting in the abstract, and it’s why OOP can boost speed and efficiency. Object - it's just a state and behavior. Before we go in detail, lets define important terms related to Object Oriented Programming. Objects pass messages to each other. This is called information hiding. Object Oriented Concepts . Various terms are used to convey the simplicity and compactness of a framework, such as Object-Oriented Programming. Basically, Java OOP concepts let us create working methods and variables, then re-use all or part of them without compromising security. If you want to change the television channel from your seat, you use a remote control. Abstraction : This concept includes hiding the internal details of program and implementing things in easy way. A good understanding of OOPs concepts can help in decision making when designing an application. In this tutorial, we are going to understand the concept of polymorphism in Java and different types of it.. What is Polymorphism? Increases sales and market share. What Is Object-Oriented Programming? Polymorphism is the foundation of Object Oriented Programming. It allows you to specialize a class in order to derive a subclass, thereby improving code reuse. Conceptually, objects are like the components of a system. In the classical definition of OOP as found in Simula and Smalltalk, inheritance was one of the key concepts. And one thing to keep in mind is that we are just using the code and not updating or changing it. Polymorphism is a significant feature of Object Oriented Principles.The word polymorphism came from two Greek words ‘poly‘ and ‘morphs‘.Here poly means many and morphs means forms.. Polymorphism represents the ability of an object to assume different forms. OOPL incorporates logical classes, objects, methods, relationships and other processes with the design of software and applications. This model compartmentalizes data into objects (data fields) and describes object contents and behavior through the declaration of classes (methods). 1)Stop object creation of a class. Grasping them is key to understanding how Java works. Each class has interface - set of public methods. This can be solved by using polymorphism. Object-oriented programming (OOP) is a software programming model constructed around objects. It means that one object can be have as another project. Video games can run anywhere from a few thousand lines of code (Cut the Rope has 15,000) to millions of lines of code long (Crysis has over a million).You can see why it's so important to write code that can be easily modified and maintained. Object Oriented Programming supports re-usability of the code. Summary of Object Oriented Programming Concepts • Everything is an Object. Object-oriented programming offers a sustainable way to write spaghetti code. In OOPs there are many ways to achieve this including encapsulation and inheritance. Products and company policies should prioritize social welfare and society in general. But each child class keeps its own methods as they are. Objects have members such as fields, properties, and methods. If there's no modifier concept, it means it would have been difficult while inheriting classes or using other OOP concepts. Data encapsulation led to the important OOP concept of data hiding. A class is like a blueprint for an object. Encapsulation is an Object Oriented Programming concept that binds together the data and functions that manipulate the data, and that keeps both safe from outside interference and misuse. We naturally think of things as objects with attributes and behaviors, and that determines how we interact with them. It lets you accrete programs as a series of patches. Encapsulation is one of the fundamental concepts in object-oriented programming (OOP). There are several major misconceptions which must be addressed when considering the use of an object-oriented method: Object-oriented Development is not a panacea - Object-oriented Development is best suited for dynamic, interactive environments, as evidenced by its widespread acceptance in CAD/CAM and engineering design systems. For example there are many possible methods to let you re-use the same functions and properties in your code, by inheriting the actual class and using those members, functions or properties, inside your derived class. OOP concepts in Java are the main ideas behind Java’s Object Oriented Programming. Here, are the important landmarks from the history: 1960 - Charles Bachman designed first DBMS system; 1970 - Codd introduced IBM'S Information Management System (IMS) 1976- Peter Chen coined and defined … At its core, it’s a logic—one we use in daily life. Societal Marketing Concept Advantages and Benefits. As we know, protected means it can be accessed by the class that is going to inherit. Same way there is object oriented programming concepts which assume everything as an object and implement a software using different objects. It gives a competitive advantage over the competitors. Inheritance; Overriding/Implementing parent Class behavior; Runtime Object binding; One of the main advantage of it is switch implementations. Thats why I have covered each and every topic in detail along with examples and diagrams in the next tutorials. If you are new to object-oriented programming languages, you will need to know a few basics before you can get started with code. • Every object is an Instance of a class. Historically, a program has been viewed as a logical procedure that takes input data, processes it, and produces output data. Encapsulation : In object oriented programming style, we use Encapsulation to implement abstraction. Although we have covered almost all the OOPs concepts here, but whatever we have learned in this guide is in brief, these topics are wide and there is so much scope to learn these topics in detail with the help of examples. Each of these three classes should have a start_engine() action. Objects also have a life cycle that includes the creation of an object, use of an object, and deletion of an object. In the class-based object-oriented programming paradigm, “object” refers to a particular instance of a class where the object can be a combination of variables, functions, and data structures. For example, say we have a car class and a scooter class and a truck class. The general idea of this mechanism is simple. Facilitate expansion and growth in the long term. It describes the idea of bundling data and methods that work on that data within one unit, e.g., a class in Java. For Example: Consider the Class of Cars. Code will always be changed. Use of private constructor in C# Sharp Programming: Following are the scenarios when we can make use of private constructor in C# code. Core OOPs Concepts. How you should design an application and what language should be used. There are two key non-OOP concepts to understand right off the bat: Duplicate code is a Bad Thing. Interfaces in Object Oriented Programming Languages . This concept is also often used to hide the internal representation, or state, of an object from the outside. Basically, your Database will have 5 tables with a foreign key defined amongst the various tables. • Computation is performed by objects communicating with each other, requesting that other objects perform actions. It is a user-defined data type, which holds its own data members and member functions, which can be accessed and used by creating an instance of that class. • Each object has its own memory, which consist of other objects. Inheritance means the use of code that is pre-written or created previously. History of DBMS. It provides a mechanism for establishing relationships and building hierarchies of class in object composition. Class: The building block of C++ that leads to Object-Oriented programming is a Class. The class … In OOP, an entity is represented as an object and objects are stored in memory. They are an abstraction, encapsulation, inheritance, and polymorphism. It helps to build a better image for the company. You are familiar with OOP concept theoretically but if interviewer ask to tell the concept with OOP concept then a lot of us are fail to answer. Object-oriented programming (OOP) is a programming language model organized around objects rather than "actions" and data rather than logic. Similarly we can imagine our car made of different objects like wheel, steering, gear etc. ― Paul GrahamFundamentals of object-oriented programmingObject-oriented programming is a programming paradigm where everything is represented as an object. An interface is a programming structure/syntax that allows the computer to enforce certain properties on an object (class). If we want to stop object creation of a class, then we can make the class constructor private. Why there's a modifier concept in OOP, is due to these reasons (any class can access other class variables using the OOP concept). Characteristics of an Object Oriented Programming language. Each object decides what to do with Or we have a method implemented for the parent class — but we’d like to use it for the children, too. Object-oriented programming language (OOPL) is a high-level programming language based on the object-oriented programming (OOP) model. So how does on object can become other, its possible through following . What is abstract interaction? The Basic OOP Concepts. The following Webopedia definitions will help you better understand object-oriented programming: Abstraction: The process of picking out (abstracting) common features of objects and procedures. Basically why we are write coding ,to solve our real… Encapsulation is used for access restriction to property or … Object-oriented programming (OOP), in its most basic sense, is a programming style used to organize code. Disadvantage of the Object Oriented Programming The message based communication between many objects in a complex system is difficult to implement. In object-oriented programming, inheritance is the mechanism of basing an object or class upon another object (prototype-based inheritance) or class (class-based inheritance), retaining similar implementation.Also defined as deriving new classes (sub classes) from existing ones such as super class or base class and then forming them into a hierarchy of classes. In this post I'll explain why OOP is used and how it makes coding easier. This post uses Python 3 code, but the concepts apply to any programming language. In computer programming, Inheritance is an eminent concept in Object Orient Programming (OOPS) Paradigm. Class: A category of objects.
