Object-oriented programming (OOP) is a programming paradigm that uses objects and their interactions to design applications. OOP techniques include data abstraction, encapsulation, inheritance, and polymorphism. A class defines members like data fields and methods to enable class instances to have state and behavior. An instance of a class represents a runtime entity and is of the type of its class. For example, an instance of the Fruit class would be a Fruit object. Inheritance allows classes to inherit and extend the attributes and behaviors of parent classes.

Object-oriented programming (OOP) is a
programming paradigm using "objects" – data
structures consisting of data fields and methods
together with their interactions – to design
applications and computer programs. Programming
techniques may include features such as data
abstraction, encapsulation, messaging, modularity,
polymorphism, and inheritance. Many modern
programming languages now support OOP.

A programming paradigm is a fundamental style
of computer programming. Paradigms differ in
the concepts and abstractions used to
represent the elements of a program (such as
objects, functions, variables, constraints, etc.)
and the steps that compose a computation
(assignment, evaluation, continuations, data
flows, etc.).

In object-oriented programming, a class is a construct that is used
as a blueprint to create instances of the class (class instances,
class objects, instance objects or just objects). A class defines
constituent members which enable class instances to have state
and behavior. Data field members (member variables or instance
variables) enable a class object to maintain state. Other kinds of
members, especially methods, enable a class object's behavior.
Class instances are of the type of the associated class.
For example, an instance of the class "Fruit" (a "Fruit" object)
would be of the type "Fruit". A class usually represents a noun, such
as a person, place or (possibly quite abstract) thing. Programming
languages that include classes as a programming construct subtly
differ in their support for various class-related features. Most
support various forms of class inheritance. Many languages also
support advanced encapsulation control features, such as access
specifiers.

Object is an run time entity.
Is an Instance of class
Represents a Place ,Person ,anything that have
some attributes.

There is a very important distinction between an
object and an instance of an object. An object is
actually a definition, or a template for instances of
that object. An instance of an object is an actual
thing that can be manipulated. For instance, we could
define a Person object, which may include such
member data as hair color, eye color, height, weight,
etc. An instance of this object could be "Dave" and
Dave has values for hair color, eye color, etc. This
allows for multiple instances of an object to be
created.

A superclass, base class, or parent class is a class
from which other classes are derived. The classes
that are derived from a superclass are known as
child classes, derived classes, or subclasses.
In object-oriented programming (OOP),
inheritance is a way to compartmentalize and
reuse code by creating collections of attributes
and behaviors called objects which can be based
on previously created objects.

Object-oriented programming (OOP) is a programming paradigm that uses objects and their interactions to design applications. OOP techniques include data abstraction, encapsulation, inheritance, and polymorphism. A class defines members like data fields and methods to enable class instances to maintain state and behavior. For example, an instance of the Fruit class would be a Fruit object. A superclass is a class that other classes are derived from, with the derived classes known as subclasses. Inheritance in OOP allows for code reuse by creating objects that are based on previously created objects.

Object-oriented programming (OOP) is a programming paradigm that designs applications around objects that contain both data and behaviors. Key concepts of OOP include data abstraction, encapsulation, inheritance, polymorphism, and messaging. Many modern programming languages support OOP through features like classes, which provide a blueprint for creating object instances that can maintain state through data fields and behavior through methods.

introduction-to-object-oriented-programming.pptkaavyashruthi

Object-oriented programming uses objects that contain data fields and methods to design applications. Key concepts include abstraction, encapsulation, inheritance, and polymorphism. A class defines shared attributes and behaviors that enable instances of that class to maintain state and behavior. An object is a runtime instance of a class that represents some entity like a person or place. Data encapsulation wraps data and code together, controlling access through public, private, and protected keywords. Inheritance allows classes to inherit attributes and behaviors from other classes in a hierarchy.

This document provides an introduction to object-oriented programming concepts. It defines object-oriented programming as a way to conceptualize a program as interacting objects. Key concepts discussed include: - Classes define templates for objects and their properties and behaviors. - Objects are instantiated from classes and represent specific instances. - Inheritance allows new classes to inherit properties from parent classes. - Encapsulation groups related properties and methods together within objects. - Polymorphism allows methods to perform different actions depending on an object's properties.

General OOP concept [by-Digvijay]Digvijay Singh Karakoti

This document provides an introduction to general object-oriented programming concepts. It discusses that OOP offers a powerful way to develop software by creating objects that encapsulate both data and functions. The core concepts of OOP explained are objects, classes, encapsulation, inheritance, polymorphism, and message passing. Objects communicate by sending and receiving messages, and classes act as templates for creating object instances that share common properties.

Objects represent entities in the real world, containing data (attributes) and behavior (methods). This paradigm simplifies complex software design by focusing on reusability, modularity, and maintainability. Below is an in-depth discussion of OOP concepts, principles, and their applications. Core Concepts of OOP 1. Objects An object is an instance of a class. It encapsulates data (attributes) and methods (functions) that operate on the data. For example, a Car object may have attributes like color and speed and methods like accelerate() or brake(). 2. Classes A class is a blueprint for creating objects. It defines the structure (attributes) and behavior (methods) that the objects of that class will have. For example: class Car: def __init__(self, color, speed): self.color = color self.speed = speed def accelerate(self): self.speed += 10 Here, the Car class provides a template, and we can create multiple car objects with different attributes. 3. Encapsulation Encapsulation is the process of bundling data and methods that operate on

The document also provides examples of how classes and objects are represented and compares procedural with object-oriented programming.

OOP Presentation.pptxDurgaPrasadVasantati

OOP is an object-oriented programming design philosophy that uses classes and objects. Everything is modeled as self-contained objects that have properties and methods. The key concepts of OOP include encapsulation, inheritance, abstraction, and polymorphism. Encapsulation combines data and methods within an object. Inheritance allows classes to inherit properties and behaviors from parent classes. Abstraction hides unnecessary details and focuses on important aspects. Polymorphism allows the same method to operate on many different types of objects.

Object oriented programmingAmit Soni (CTFL)

Object-oriented programming (OOP) uses objects that contain data and methods. The four pillars of OOP are abstraction, encapsulation, inheritance, and polymorphism. Abstraction hides unnecessary details, encapsulation shields an object's internal representation, inheritance allows subclasses to inherit attributes of superclasses, and polymorphism enables processing objects differently depending on their type. Classes define objects and contain data fields and methods, with objects being instances of classes that allocate space in memory. Access control in Java includes private, public, default, and protected access types.

Basic concepts of oopsChandrakiran Satdeve

Object oriented programming focuses on data and uses a bottom-up design approach, while procedural programming focuses on functions and uses a top-down design approach. Some key features of OOP include objects, classes, data abstraction, encapsulation, inheritance, polymorphism, and reusability. An object contains data fields and methods, and a class defines the blueprint for objects. Inheritance allows code reuse through derived classes extending existing base classes. Polymorphism allows the same function to operate on different types, while overloading gives the same operation different meanings based on context.

CPP-Unit 1.pptxYashKoli22

Unit 1 introduces the basics of object-oriented programming (OOP). OOP treats data as objects that contain both data fields (properties) and methods (behaviors). Classes are templates that are used to create objects. Some key principles of OOP include encapsulation, which binds an object's data and methods together, inheritance which allows classes to share structures and behaviors of other classes, and polymorphism which allows different classes to have similarly-named methods that work in different ways. OOP aims to make code reusable, modular, and adaptable to changing requirements compared to traditional procedural programming.

Lecture 1 oopTony Apreku

The document provides an introduction to object-oriented analysis and design (OOAD). It defines OOAD as a process of analyzing problems and developing solutions by planning in UML or pseudocode. Object-oriented analysis focuses on discovering key classes, while object-oriented design models real-world objects and communication between objects through interfaces. The document also outlines principles of object-oriented programming including classes, objects, inheritance, and polymorphism.

OopsSankar Balasubramanian

Object-oriented programming (OOP) involves splitting a program into objects that contain both data and functions. OOP allows developers to define objects, their properties, and relationships. Classes are blueprints that define objects and don't use memory, while objects are instances of classes that hold both data and methods. Key concepts of OOP include inheritance, abstraction, polymorphism, and encapsulation.

本資料「To CoT or not to CoT?」では、大規模言語モデルにおけるChain of Thought（CoT）プロンプトの効果について詳しく解説しています。 CoTはあらゆるタスクに効く万能な手法ではなく、特に数学的・論理的・アルゴリズム的な推論を伴う課題で高い効果を発揮することが実験から示されています。一方で、常識や一般知識を問う問題に対しては効果が限定的であることも明らかになりました。複雑な問題を段階的に分解・実行する「計画と実行」のプロセスにおいて、CoTの強みが活かされる点も注目ポイントです。 This presentation explores when Chain of Thought (CoT) prompting is truly effective in large language models. The findings show that CoT significantly improves performance on tasks involving mathematical or logical reasoning, while its impact is limited on general knowledge or commonsense tasks.

A Comprehensive Investigation into the Accuracy of Soft Computing Tools for D...Journal of Soft Computing in Civil Engineering

This study will provide the audience with an understanding of the capabilities of soft tools such as Artificial Neural Networks (ANN), Support Vector Regression (SVR), Model Trees (MT), and Multi-Gene Genetic Programming (MGGP) as a statistical downscaling tool. Many projects are underway around the world to downscale the data from Global Climate Models (GCM). The majority of the statistical tools have a lengthy downscaling pipeline to follow. To improve its accuracy, the GCM data is re-gridded according to the grid points of the observed data, standardized, and, sometimes, bias-removal is required. The current work suggests that future precipitation can be predicted by using precipitation data from the nearest four grid points as input to soft tools and observed precipitation as output. This research aims to estimate precipitation trends in the near future (2021-2050), using 5 GCMs, for Pune, in the state of Maharashtra, India. The findings indicate that each one of the soft tools can model the precipitation with excellent accuracy as compared to the traditional method of Distribution Based Scaling (DBS). The results show that ANN models appear to give the best results, followed by MT, then MGGP, and finally SVR. This work is one of a kind in that it provides insights into the changing monsoon season in Pune. The anticipated average precipitation levels depict a rise of 300–500% in January, along with increases of 200-300% in February and March, and a 100-150% increase for April and December. In contrast, rainfall appears to be decreasing by 20-30% between June and September.
