Essay: Main Characteristics And Features Of Object Oriented Programming

Nov 09,  · Features Of OOPS Concepts Break down requirement into objects. Built object hierarchies and interaction rather than program control flow. Easy to change the code according to the requirements. Nov 24,  · The OOP language supports the features of normal programming languages as well as some important concepts and terminologies that make them popular among the programming methodology. In Object.

This page of the essay has words. Download the full version above. The following task clearly explains the descriptions of the features and characteristics of the features of the object oriented programming. There are twelve principles of oop which is stated below. How to do my eyebrows Object oriented programming is how to be a hotshot of the newest and most powerful paradigms.

The Object-Oriented Programming mentions to the programming methodology based on the objects, in its place of just procedures and functions. These objects are planned into classes, which are allowing to the individual objects to be group together.

Each and every object has a structure related to other objects in the class, but it can be allocated individual features. An object can also call as method or functions, particular to that object.

The Individual characters are may be defined as objects, according what are the features of oops the object which are allows them to have different skill, appearances, and abilities.

The Object oriented programming makes it easier to the programmers to design and organize software programs. The important features which are help to design the object-oriented programming and design is given below:. According to the Object Oriented programming language, it has to allow working with classes and objects as well as the implementation and use of the main four fundamental object oriented principles and concepts.

The process, or mechanism, by which you combine code and the data it manipulates into a single unit, is commonly referred to as encapsulation. Encapsulation provides a layer of security around manipulated data, protecting it from external interference and misuse.

In Java, this is supported by classes and objects. New data types classes can be defined as extensions to previously defined types. Parent Child. More precisely, it is the ability for different objects to respond to the same message in different ways. In the above figure 4, it is shown that a simple thread could be transformed into different shapes same way polymorphism means that it could change to many different types.

Abstraction is a concept which facilitates to extract out the essential information of an object. In OOP Object orients programmingAbstraction Facilitates the easy conceptualization of real world objects into the software program. Abstraction facilitates the easy conceptualization of real world objects, by eliminating the unnecessary details of the object. Unnecessary details?

Yes, all the similar objects when you generalize, you will drop the uncommon details about the objects. What should my blood sugar be after meals the features and principles are explained clearly with examples in the above task at it also describes what is OOP and its characteristics. The Following task contains what is an object and what is a class it describes the difference between them and also it includes examples of what is an object and class.

The Objects are the key to understanding object-oriented program. In the real objects are the entities from which the world is involved. Every this that occurs around the world is connected to the interfaces between the objects in the world just as atoms, which are objects, associate to form partials how to make spy cam larger objects, the interacting entries in the world can be thought of as relation between and amongst both singular atomic as well as compound composed objects.

For each object that you see, how to grow lavender plants in pots yourself two questions the questions are given below:. The state of an object includes all of the static properties of the object plus the current dynamic values of each of these states. A state is distinctive or an inherent characteristic, quality, trait, or feature that distribute to making an object uniquely.

Word uses an attribute, or data member, to refer to the state of an object. Behavior is how an object reacts and acts, in the terms of properties changes and interactions with other objects. An operation is some action that one object performs upon another in order to promote a reaction. The word called as method that uses to describe object method in java. Entreating a method reasons the behavior to take place. The class is simply a representation of a type of object.

The class is a design or plan or template or a set of instructions to build a specific type of object. Each and Every object is built from a class. Every class should be designed and programmed to complete one, and only one, thing. Each and every class is designed to have only one single responsibility; many classes are used to build an entire application.

In this task I have explained what is object and what class it describes the difference between them is and clearly explained with suitable examples of what is an object and class.

The following task contains all the details of what is a crc card and how it relates to the system and I have drawn all the crc card according to the current system below. Originally their purpose was to teach what does altria group do programmers the object oriented paradigm. CRC is a lightweight approach object oriented analysis technique. Class Responsibility Collaborator modeling frequently includes the users, analysts and developers in a modeling and design process, bringing together the whole development team to form a common understanding of an Object Oriented development project.

The technique has since been developed to become valued beyond the education syllabus. The Class represents a collection of similar objects. The Objects are things of interest in the system being modeled. They can be a thing, person or thing or any other concept important to the system at hand.

The Responsibility is whatever that the class does or knows. These responsibilities are the things that the class has knowledge about itself or things the class can do with the knowledge it has. For the example, the person class might have knowledge responsibility for its name, address, and contact number. The Collaboration is another class that is used to get information or perform actions for the class at hand.

It often works with a particular class to complete a step. The system manager responsibilities are what job positions are available in groceries stores the cities, create rooms, create room type, create hotel, book room, check the available rooms and print the system details. It is collaborating to the city, hotel, room, room type, available room, book room and display system details.

The collaboration card is given below. The city responsibilities are add city and maintain the city. The city is collaborating to the city, hotel, system manager and display system details. The hotel responsibilities are add hotel and maintain the hotel.

The hotel is collaborating to the city, hotel, room, system manager and display system details. The room type responsibilities are create room type and maintain the room type detail.

The room type is collaborating to the hotel, room and system manager. The room responsibilities are create room and maintain the room detail. The room is collaborating to the hotel, room type, system manager, book room, available room and display system details. The book room responsibilities are book room, maintain the booking room and maintain the room details.

The book room is collaborating to the hotel, room, room type, available room, system manager and display how to make your own cupcake tower details. The Available room responsibilities are find available room and maintain the room detail. The Available room is collaborating to the hotel, room and system manager. The display system details a responsibility display the system details and its collaborating to the city, hotel, room, room type, available room, book room and system manager.

Above I have drawn CRC card for the current system. The following task I have clearly explains about the class diagram and drawn the class diagram for the current system. The Class diagrams are used for a wide variety of needs, including both conceptual or domain modeling and detailed design modeling. The class diagram shows how the different entities communicate to each other. Simply to say the class diagram shows the static structures of the system.

The class diagram displays the logical classes and also to show implementation classes. The class is represented on the class diagram as a rectangle with three. According to the task I have explained what is class diagram and drawn a class diagram for the current system. In the question Number 3. According to that have explained about the object oriented programing language and implement the each and every class.

According to the task I have clearly explained about object oriented programing Language and Implement classes by using Java language. According to this task I have implement the system manager main class by using java programing language.

Following this task contains about object what are the features of oops test mechanisms and types. I have clearly explained about them below. The variable delivers with the named storage that programs can operate. In Java Each Variable has a specific type.

The range of values stored within that memory and the set of processes that can be applied to the variable. Before compile the program first complier must declare the all variables. In java program language the variables are dived into three types. Debugging is the method of engineering hard ware device or locating and fixing errors in computer program code. To debug the hardware device or program is to begin with the problem and separate the source of problem, after that fix it.

The user does not know how to fix the problem the user must learn about the problem to be able to escape it until it is permanently fixed. Debugging is a required method in almost any new hardware or software development method. The debugging is done as the result of the small unit test of the system.

The most computer programs and many programmed hardware devices cover thousands of lines of code. The Debugging tools are called as debuggers.

What is object-oriented programming?

Nov 29,  · According to the principals there twelve fundamental features there are given below. Encapsulation. Data Abstraction. Inheritance. Polymorphism. Extensibility. Persistence. Delegation. Generality. Object Concurrency. Event Handling. Apr 02,  · Object-oriented programming combines a group of variables (properties) and functions (methods) into a unit called an "object." These objects are organized into classes where individual objects can be grouped together. OOP can help you consider objects in a program's code and the different actions that could happen in relation to the objects. Apr 19,  · When you approach a programming problem in an characteristics object oriented programming language, you no longer ask how the problem will be divided into functions, but how it will be divided into objects. Thinking in terms of objects, rather than functions, has a surprisingly helpful effect on how easily programs can be designed.

When you approach a programming problem in an characteristics object oriented programming language , you no longer ask how the problem will be divided into functions, but how it will be divided into objects.

Thinking in terms of objects, rather than functions, has a surprisingly helpful effect on how easily programs can be designed. This results from the close match between objects in the programming sense and objects in the real world. What kinds of things become objects in object oriented programs? The answer to this is limited only by your imagination, but here are some typical categories to start you thinking:. The match between programming objects and real world objects is the happy result of combining data and functions: The resulting objects offer a revolution in program design.

No such close match between programming constructs and the items being modeled exists in a procedural language. In OOP we say that objects are members of classes. What does this mean? Almost all computer languages have built in data types. You can declare as many variables of type int as you need in your program:. In a similar way, you can define many objects of the same class, as shown in Figure. A class serves as a plan, or blueprint. It specifies what data and what functions will be included in objects of that class.

A class is thus a description of a number of similar objects. This fits our non technical understanding of the word class. Prince, Sting, and Madonna are members of the rock musician class. The idea of classes leads to the idea of inheritance.

In our daily lives, we use the concept of classes divided into subclasses. We know that the animal class is divided into mammals, amphibians, insects, birds, and so on. The vehicle class is divided into cars, trucks, buses, motorcycles, and so on. Cars, trucks, buses, and motorcycles all have wheels and a motor; these are the defining characteristics of vehicles. In addition to the characteristics of object oriented programming shared with other members of the class, each subclass also has its own particular characteristics: Buses, for instance, have seats for many people, while trucks have space for hauling heavy loads.

This idea is shown in Figure. Notice in the figure that features A and B, which are part of the base class, are common to all the derived classes, but that each derived class also has features of its own. In a similar way, an OOP class can become a parent of several subclasses. These are called derived classes. Derived classes inherit some characteristics from their base class, but add new ones of their own.

Inheritance is somewhat analogous to using functions to simplify a traditional procedural program. If we find that three different sections of a procedural program do almost exactly the same thing, we recognize an opportunity to extract the common elements of these three sections and put them into a single function. The three sections of the program can call the function to execute the common actions, and they can perform their own individual processing as well.

Similarly, a base class contains elements common to a group of derived classes. As functions do in a procedural program, inheritance shortens an object oriented program and clarifies the relationship among program elements.

Once a class has been written, created, and debugged, it can be distributed to other programmers for use in their own programs. This is called reusability. It is similar to the way a library of functions in a procedural language can be incorporated into different programs. However, in OOP, the concept of inheritance provides an important extension to the idea of reusability. A programmer can take an existing class and, without modifying it, add additional features and capabilities to it.

This is done by deriving a new class from the existing one. The new class will inherit the capabilities of the old one, but is free to add new features of its own. For example, you might have written or purchased from someone else a class that creates a menu system, such as that used in Windows or other Graphic User Interfaces GUIs. To do this, you simply create a new class that inherits all the capabilities of the existing one but adds flashing menu entries. The ease with which existing software can be reused is an important benefit of OOP.

Many companies find that being able to reuse classes on a second project provides an increased return on their original programming investment. One of the benefits of objects is that they give the programmer a convenient way to construct new data types. Suppose you work with two-dimensional positions such as x and y coordinates, or latitude and longitude in your program.

You would like to express operations on these positional values with normal arithmetic operations, such as. By creating a class that incorporates these two values, and declaring position1, position2, and origin to be objects of this class, we can, in effect, create a new data type.

The answer is that we can define new behaviors for these operators. These operations will be member functions of the Position class.

Using operators or functions in different ways, depending on what they are operating on, is called polymorphism one thing with several distinct forms. Overloading is a kind of polymorphism; it is also an important feature of OOP. Log in to leave a comment. Automated page speed optimizations for fast site performance.
