Object-Oriented Programming (OOP) uses "objects" to model realworld objects. Object- Programming (OOP) consist of some important concepts namely. 5, Issue 09, | ISSN (online): Object-Oriented Programming and its Concepts Asha Rani M1 Kavana M D2 Parvathy S J3 Shreelakshmi C M4 1,2 . CSj, Stanford. Handout #3. Winter, Nick Parlante. OOP Concepts. Object Oriented Programming, OOP, is the must influential paradigm of our time.

In spite of being used by almost the help of the existing class, we can create a new class everyone since , it was not surprising that it would be using same functions [26]. The existing class will be used as so famous and adapted by majority after the invention of a reference class for the derived class. To organize our Internet [10].

Also, the concepts of OOP play a very vital grammar or language in a systematic way in the program, role in programming language. OOP provides good design we must use inheritance. The reusability of the same patterns which are basically a figurative model of the design grammar in the new sub-class would reduce execution and of object; called class.

It gives references for the user to compilation time [27].

Reusing the attributes, methods make create new objects and is very user friendly. It also gives us the task of programming easy and the reusability of the code an option of sharing the code, which is called as inheritance from our existing class to our new derived class is very where the old methods can be reused into new class.

By feasible for the users [28]. By making the use of inheritance, giving prior error handling method, it gives user to recheck we save the execution time and the programming the code and compile the run-time errors with the use of complexity. Inheritance has "is-a" relationship with the exception handling [11]. Object following this relationship technique [29].

For any web application or a program to come into D. Polymorphism existence, the basic requirement is the way to code that program. The outline of any program has to be done prior The fast execution of any process or program is the main developing it.

For developing any program, there is motivation behind the programmer's logic.

There are many necessity of an object in OOP [12]. They act as mediator aspects to think upon when coding is done for any program, between the program and the methods which are added with for example, the programs logic, the scope, the semantics of it. Also, privacy is the most important thing in any the program.

One does not want to put his time and efforts application or program development hence, objects contain in giving each variable or an object a specific individual private data as we do not want any hacker or unauthorized meaning and definition; hence the concept of polymorphism person to gain access to our data [13]. Only a few authorized was introduced.

Polymorphism gives the way to represent users can access the data through certain operations. Object variables as a group or a common way to represent the is anything that exists and has some value [14]. Suppose a variables [30]. The code usage gives the programmer to person has his name, age and gender: We could define All rights reserved by www. The Importance of Object-Oriented to perform the action of execution quickly. By allowing Programming in the Era of Mobile Development. Binding of http: By giving access to users on defining their objects [12] Reyna, A.

Object-oriented programming as an limits to certain classes, the user gets the leverage to use the alternative to industrial control. In Electrical same object at different positions with different functions Engineering, Computing Science and Automatic [34]. OOP [35]. Object-oriented programming: In Aerospace IV.

Using object- programming environment. Also it has shown a very drastic oriented programming in computational change in the nature of programming by the advent of electromagnetic codes. Orlandi, and F. Network programming environment. Object, which is a crucial part of synthesis using object-oriented programming. In OOP, is the basis for representing of any information. Class; Electrotechnical Conference, Inheritance, which gave the concept of reusability Mediterranean.

What is OOPS?

Al-A'ali, and M. Girgis, Object- Hence concluding, OOP plays a vital role and its usage is oriented programming for structured procedural being increasing in every programming module.

Hierarchical Inheritance: When a class has more than one child classes sub classes or in other words, more than one child classes have the same parent class, then such kind of inheritance is known as hierarchical.

If we talk about the flowchart, Class B and C are the child classes which are inheriting from the parent class i.

Since multiple inheritance is not supported in Java as it leads to ambiguity, so this type of inheritance can only be achieved through the use of the interfaces. Now we have learned about inheritance and their different types. Object Oriented Programming : Encapsulation Encapsulation is a mechanism where you bind your data and code together as a single unit.

It also means to hide your data in order to make it safe from any modification. What does this mean? The best way to understand encapsulation is to look at the example of a medical capsule, where the drug is always safe inside the capsule. Similarly, through encapsulation the methods and variables of a class are well hidden and safe.

Object Oriented Programming – Java OOPs Concepts With Examples

We can achieve encapsulation in Java by: Declaring the variables of a class as private. Providing public setter and getter methods to modify and view the variables values. We have then created a getter and setter methods through which we can get and set the name of an employee. Through these methods, any class which wishes to access the name variable has to do it using these getter and setter methods.

Object Oriented Programming : Abstraction Abstraction refers to the quality of dealing with ideas rather than events. It basically deals with hiding the details and showing the essential things to the user. If you look at the image here, whenever we get a call, we get an option to either pick it up or just reject it. But in reality, there is a lot of code that runs in the background.

Therefore, abstraction helps to reduce complexity. Now what does the abstract keyword mean? If a class is declared abstract, it cannot be instantiated, which means you cannot create an object of an abstract class. Also, an abstract class can contain abstract as well as concrete methods. Firstly, with the advent act as an object and the rest would be related attributes.

The of inheritance we can avoid the redundancy in our code and concept of private data and operations on that particular set can increase the extensibility factor of our class, which was of objects is very essential to understand [15].

For not possible while implementing Procedural Oriented communication between different sets of objects, a Programming. Secondly, by implementing the concept of particular rule is followed, which, is mandatory [16].

The data hiding, the programmer can develop secure contents within the objects are secure, and the structure and programmable code which cannot be altered in other parts of content in object is very necessary for users [17].

With the option of having many forms of objects B. Class to work together, there is no hindrance of one object on other. The understanding of the software becomes much A class in OOP is the main body of any program.

All the easy while dealing with OOP. For communication and methods and its definitions are presented inside the class. Every class contains objects inside it which are executable.

It is a collection of distinct objects with which II. Class features the data definition, i. Classes use attributes and impact of Object- Oriented Programming and its concepts functions to operate the given data [20]. The classes contain on the programming world. The Research Method used a certain functions for its operation which are used for the review centric approach which was done on the articles and user-defined functionality [21].

In- class gives us a clear idea of which class has the priority to depth research was done on the impacts which object execute and function and the class follows a proper order of oriented programming has done in the programming execution [22].

Class is the key element in software paradigm. The University of Bridgeport Library was a monitoring and implementing the concepts of OOP [23] source to find out various journals and articles on OOP and its various concepts. The practical implementation was C. Inheritance carried out of the concepts of OOP in the programs which Inheritance gives any user the provision to utilize the same showed the importance of OOP.

The process of deriving a whole new class III. The emergence of Object-Oriented less as we are using the same attributes which have been Programming increased drastically with the advent of the compiled by the system and, they are error free [25]. With Internet for business sector. In spite of being used by almost the help of the existing class, we can create a new class everyone since , it was not surprising that it would be using same functions [26].

The existing class will be used as so famous and adapted by majority after the invention of a reference class for the derived class.

C++ Object Oriented

To organize our Internet [10]. Also, the concepts of OOP play a very vital grammar or language in a systematic way in the program, role in programming language. OOP provides good design we must use inheritance. The reusability of the same patterns which are basically a figurative model of the design grammar in the new sub-class would reduce execution and of object; called class.

Advantages of OOPS:

Polymorphism gives the way to represent users can access the data through certain operations. Object variables as a group or a common way to represent the is anything that exists and has some value [14].

Suppose a variables [30]. The code usage gives the programmer to person has his name, age and gender: We could define All rights reserved by www.

OOPS Concepts in Java with Examples

The Importance of Object-Oriented to perform the action of execution quickly. By allowing Programming in the Era of Mobile Development.Wu, and K. So an interface basically is a group of related methods with empty bodies. The concepts used are and work along [9]. There are four basic concepts motivation of creation of elements, for example, closed which are to be emphasized.

Wu, and K. The outline of any program has to be done prior The fast execution of any process or program is the main developing it. Object-oriented programming as an limits to certain classes, the user gets the leverage to use the alternative to industrial control.
