In this page, we will learn about the basics of OOPs. Object-Oriented Programming is a paradigm that provides many concepts, such as inheritance , data binding , polymorphism , etc. Simula is considered the first object-oriented programming language. The programming paradigm where everything is represented as an object is known as a truly object-oriented programming language. The main aim of object-oriented programming is to implement real-world entities, for example, object, classes, abstraction, inheritance, polymorphism, etc.

Object means a real-world entity such as a pen, chair, table, computer, watch, etc. Object-Oriented Programming is a methodology or paradigm to design a program using classes and objects. It simplifies software development and maintenance by providing some concepts:. Any entity that has state and behavior is known as an object. For example, a chair, pen, table, keyboard, bike, etc. It can be physical or logical. An Object can be defined as an instance of a class. An object contains an address and takes up some space in memory.

Objects can communicate without knowing the details of each other's data or code. The only necessary thing is the type of message accepted and the type of response returned by the objects. Example: A dog is an object because it has states like color, name, breed, etc. A class can also be defined as a blueprint from which you can create an individual object. Class doesn't consume any space. When one object acquires all the properties and behaviors of a parent object , it is known as inheritance.

It provides code reusability. It is used to achieve runtime polymorphism. If one task is performed in different ways , it is known as polymorphism. For example: to convince the customer differently, to draw something, for example, shape, triangle, rectangle, etc. Hiding internal details and showing functionality is known as abstraction. For example phone call, we don't know the internal processing.

Binding or wrapping code and data together into a single unit are known as encapsulation. For example, a capsule, it is wrapped with different medicines. A java class is the example of encapsulation. Java bean is the fully encapsulated class because all the data members are private here. Coupling refers to the knowledge or information or dependency of another class.

It arises when classes are aware of each other. If a class has the details information of another class, there is strong coupling. In Java, we use private, protected, and public modifiers to display the visibility level of a class, method, and field. You can use interfaces for the weaker coupling because there is no concrete implementation. Cohesion refers to the level of a component which performs a single well-defined task.

A single well-defined task is done by a highly cohesive method. The weakly cohesive method will split the task into separate parts. The java. However, the java. Association represents the relationship between the objects.

Here, one object can be associated with one object or many objects. There can be four types of association between the objects:. Let's understand the relationship with real-time examples. For example, One country can have one prime minister one to one , and a prime minister can have many ministers one to many. Also, many MP's can have one prime minister many to one , and many ministers can have many departments many to many.

Aggregation is a way to achieve Association. Aggregation represents the relationship where one object contains other objects as a part of its state. It represents the weak relationship between objects. It is also termed as a has-a relationship in Java. Like, inheritance represents the is-a relationship. It is another way to reuse objects. The composition is also a way to achieve Association. The composition represents the relationship where one object contains other objects as a part of its state.

There is a strong relationship between the containing object and the dependent object. It is the state where containing objects do not have an independent existence. If you delete the parent object, all the child objects will be deleted automatically. We can provide the solution of real word problem if we are using the Object-Oriented Programming language.

Object-based programming language follows all the features of OOPs except Inheritance. JavaScript and VBScript are examples of object-based programming languages.

Java OOPs Concepts

Create sound software designs with data structures that use modern object-oriented design patterns! Author Bruno Preiss presents the fundamentals of data structures and algorithms from a modern, object-oriented perspective. The text promotes object-oriented design using Java and illustrates the use of the latest object-oriented design patterns. Virtually all the data structures are discussed in the context of a single class hierarchy. This framework clearly shows the relationships between data structures and illustrates how polymorphism and inheritance can be used effectively.

It allows users to create objects they want and create methods to handle those objects. The basic concept of OOPs is to create objects, re-use them throughout the program, and manipulate these objects to get results. OOP meaning "Object Oriented Programming" is a popularly known and widely used concept in modern programming languages like Java. It is only a logical component and not the physical entity. Its properties data can be price or speed of these cars. While the methods may be performed with these cars are driving, reverse, braking etc.

Object Oriented Programming – Java OOPs Concepts With Examples

OOPs (Object-Oriented Programming System)

In the procedure-oriented approach, the problem is viewed as a sequence of things to be done, such as reading, calculating and printing. Procedure-oriented programming basically consists of writing a list of instructions into groups known as functions. Characteristics: 1. Emphasis is on doing things algorithms 2. Large programs are divided into smaller programs known as functions 3. Most of the functions share global data 4. Functions transforms data from one form to another 5.

 Не поддается, сэр? - с трудом произнесла.  - А как же принцип Бергофского. О принципе Бергофского Сьюзан узнала еще в самом начале своей карьеры. Это был краеугольный камень метода грубой силы. Именно этим принципом вдохновлялся Стратмор, приступая к созданию ТРАНСТЕКСТА.

Но Стратмор ее не слышал. Его жизнь окончена. Тридцать лет отдал он служению своей стране. Этот день должен был стать днем его славы, его piece de resistance, итогом всей его жизни - днем открытия черного хода во всемирный стандарт криптографии. А вместо этого он заразил вирусом главный банк данных Агентства национальной безопасности. И этот вирус уже невозможно остановить - разве что вырубить электроэнергию и тем самым стереть миллиарды бит ценнейшей информации. Спасти ситуацию может только кольцо, и если Дэвид до сих пор его не нашел… - Мы должны выключить ТРАНСТЕКСТ! - Сьюзан решила взять дело в свои руки.

Казалось, что с той минуты, когда рано утром ему позвонил Стратмор, прошла целая вечность.

Агент Колиандер нажал несколько кнопок, и кадры стали сменяться быстрее. Люди на подиуме с нетерпением ждали, когда на экране появится их бывший сослуживец Энсей Танкадо. Ускоренное проигрывание видеозаписи придавало изображению некоторую комичность. Вот Танкадо вышел на открытое место и залюбовался открывшимся перед ним зрелищем. Он козырьком поднес руку к глазам и стал разглядывать шпили над внушительным фасадом.

Внезапно откуда-то появился пожилой человек, подбежал к Танкадо и опустился возле него на колени. Халохот замедлил шаги.

    Object-oriented programming OOP is a programming paradigm based on the concept of " objects ", which can contain data and code: data in the form of fields often known as attributes or properties , and code, in the form of procedures often known as methods.
