This document discusses key concepts of object-oriented design and programming. It defines object-oriented design as planning a system of interacting objects to solve software problems. It describes object-oriented programming as representing concepts as objects that have data fields and methods. The document outlines some key pillars of object-oriented programming including inheritance, which allows code reuse; encapsulation, which protects data; and access modifiers like public, private, and protected, which control object accessibility.

Advance Concepts of
Object Oriented Design

Objectives
• Design principles of Object Oriented Programming
• Pillars of Object Oriented Programming
Concept of Object Oriented Design
The process of planning a system of interacting objects for the purpose
of solving a software problem .it is one of the approaches for software
design

Object Oriented programming
Object Oriented programming (OOP) is a programming
paradigm that represents concepts as “objects "that have data
fields (attributes that describe the object) and associates
procedures known as methods. Objects ,which are instances of
classes ,are used to interact with one another to design
applications and computer programs
Examples of Object Oriented languages include Smalltalk C++
and objective-c Eiffel .Python ,Ruby java C# Visual Basic .NET

Pillars of Object Oriented
Programming
Inheritance
one of the primary concepts of object-oriented programming.it
allows you to reuse existing code, through effective employment
of reuse you can save time in your programming

Using System;
public class Parent Class
{
public Parent Class()
{
Console.WriteLine(“Parent Constructor”);
}
public void print()
{
Console.WriteLine(“I am parent class ”);
}
}
Public Child Class :Parent Class
public Child Class()
{
Console.WriteLine(“Child Constructor ”);
}
}
Public static void main ()
{
Child Class child = new Child Class();
child.print();
}
}
The top class is named as parent
class and the main class is called
child class, what we want to do
is create a child class as the base
class of child class . This is
accomplished through the child
class declaration as public class.
the base class is specified by
adding a colon “:”; after the
derived class identifier and then
specifying the base class name .

Sealed Class
Sealed Classes are used to restrict the inheritance feature of object
oriented programming once a class is defined as sealed class this
class cannot be inherited
Encapsulation
Encapsulation is the process of putting data and the operations
(functions) that can be performed on data into a single container
called class
Now any programmer can use this class without knowing how is
implemented .Due to encapsulation data is insulated thus not directly
accessible from the outside world ,this is known as data hiding
Encapsulation is not data hiding but Encapsulation leads to data
hiding
Access Modifier
Access modifier are keywords used to specify the declared
accessibility of a member or a type .This section introduces the four
access modifiers

Public
The public keyword is an access modifier for types and type
members. Public access is the most permissive access level
there are no restriction accessing public members
Using system
class bank account Public
{
public decimal Get Amount()
{
return 1000.00m;
}
}

Using system
class MyClass
{
protected int x;
protected int y;
}
class My DerivedC:MyClass
{
public static void main()
{
MyDerived mC=new My DerivedC();
// Direct access to protected members:
mC.x = 10;
mC.y = 15;
Console.WriteLine(“ x = {0}, y = {1} ”. mC.x. mC,y);
}
}

$Private Private keyword is a member access modifier .A Private member is least permissive access level .Private member are accessible within the body of the class Using System class Bank Account Private { private string m_name ; public string Customer Name { get { get { return m_name;} set{ m_name = value;} } }$

Internal
The Internal keyword is a member access modifier for types and type members
A Internal member are accessible from with in the files in the same assembly

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.

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.

Key concepts are explained such as classes defining attributes and behaviors of objects, objects being instances of classes, and communication between objects occurring through messages. The four main principles of OOP - inheritance, abstraction, encapsulation, and polymorphism - are also summarized.

Object Oriented Programming ppt presentationAyanaRukasar

This document discusses the key concepts of object-oriented programming including classes, objects, inheritance, polymorphism, abstraction, and encapsulation. Classes are blueprints that define properties and behaviors for objects. Inheritance allows classes to inherit attributes and methods from parent classes. Polymorphism enables data to take multiple forms. Abstraction hides unnecessary details and encapsulation bundles data with the methods that operate on that data.

Object Oriented Languagedheva B

The document discusses object-oriented programming languages like C++, Smalltalk, and Java. It covers the basic concepts of object-oriented programming including objects, classes, encapsulation, inheritance, and polymorphism. Key points about each language are provided, such as C++ being an extension of C and introducing classes, Smalltalk being one of the earliest languages to support OOP, and Java combining elements of C++ and Smalltalk. Sample code in each language is also shown.

Object Oriented Programming Conceptsthinkphp

The document discusses key concepts in object-oriented programming including objects, classes, messages, and requirements for object-oriented languages. An object is a bundle of related variables and methods that can model real-world things. A class defines common variables and methods for objects of a certain kind. Objects communicate by sending messages to each other specifying a method name and parameters. For a language to be object-oriented, it must support encapsulation, inheritance, and dynamic binding.

Constructors in C++RubaNagarajan

Constructor is a special member function that initializes objects of a class. Constructors have the same name as the class and do not have a return type. There are two types of constructors: default constructors that take no parameters, and parameterized constructors that allow passing arguments when creating objects. Constructors are automatically called when objects are created to initialize member variables, unlike regular member functions which must be explicitly called.

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.

the Concept of Object-Oriented ProgrammingAida Ramlan II

This document provides an introduction to object-oriented programming (OOP). It discusses key OOP concepts like enabling code reuse through inheritance and modifying existing code more easily. While OOP became popular in the 1980s, its origins date back to the Simula programming languages from the 1960s. OOP provides clear modular structures, makes code maintenance and modification easier, and offers a framework for code libraries. The document also defines important OOP terminology like classes, objects, encapsulation, abstraction, inheritance, polymorphism and distinguishes between abstraction and encapsulation.

Computer Science-Data Structures :Abstract DataType (ADT)St Mary's College,Thrissur,Kerala

The document discusses abstract data types (ADTs) and several common data structures, including stacks, queues, linked lists, trees, and their applications. An ADT defines a data type and operations on that data type without specifying how those operations are implemented. Common programming languages define simple ADTs like integers, while more complex ADTs like lists, stacks and queues must be explicitly defined. The key operations and applications of each data structure are described.

[OOP - Lec 19] Static Member FunctionsMuhammad Hammad Waseem

Static member functions can be accessed without creating an object of the class. They are used to access static data members, which are shared by all objects of a class rather than each object having its own copy. The examples show declaring a static data member n and static member function show() that prints n. show() is called through the class name without an object. Each object creation in the constructor increments n, and show() prints the updated count.

It also discusses indefinite loops with while and definite loops with for, and how to break and continue loops. Finally, it covers pass and return statements, local and global scopes, function composition, lambda functions, string slicing, string methods, and that strings are immutable in Python.

Basic concepts of object oriented programmingSachin Sharma

This document provides an overview of basic concepts in object-oriented programming including objects, classes, data abstraction, encapsulation, inheritance, polymorphism, binding, and message passing. Objects are run-time entities with state and behavior, while classes define the data and behavior for objects of a similar type. Encapsulation binds data and functions within a class, while inheritance allows new classes to acquire properties of existing classes. Polymorphism enables one function to perform different tasks. Binding determines how function calls are linked, and message passing allows objects to communicate by sending requests.

Abstraction javaMahinImran

Need of object oriented programmingAmar Jukuntla

Object oriented programming (OOP) addresses limitations of procedural programming by dividing programs into objects that encapsulate both data and behaviors. OOP supports features like inheritance, polymorphism, and abstraction. Inheritance allows new classes to inherit attributes and behaviors from parent classes, polymorphism allows the same message to be interpreted differently depending on the object receiving it, and abstraction focuses on essential characteristics without implementation details. These features help make programs more modular, reusable, and maintainable.

Introduction to oopcolleges

This document provides an introduction to object-oriented programming (OOP) concepts. It defines OOP as a design philosophy that groups everything as self-sustainable objects. The key OOP concepts discussed are objects, classes, encapsulation, abstraction, inheritance, polymorphism, method overloading, method overriding, and access modifiers. Objects are instances of classes that can perform related activities, while classes are blueprints that describe objects. Encapsulation hides implementation details within classes, and abstraction focuses on what objects are rather than how they are implemented.

PolymorphismRaffaele Doti

Polymorphism refers to the ability of an object to take on multiple forms. In Java, polymorphism occurs when a reference variable can refer to objects of different subclasses. This allows methods to behave differently depending on the actual object being referred to. There are three main forms of polymorphism in Java: method overriding, abstract method implementation, and interface implementation. Polymorphism provides benefits like simplicity and extensibility by allowing code to interact generically with base types and subclasses without needing specific type details.

Unit 1 OOSE ChhayaShelake

Object oriented programming conceptsrahuld115

This presentation provides an overview of object-oriented programming (OOP). It discusses key OOP concepts including objects, classes, encapsulation, inheritance, polymorphism, and message passing. Objects are instances of classes that have both data and behaviors. Classes define common properties and methods for objects. Encapsulation binds together an object's data and methods, while inheritance establishes a hierarchy where derived classes inherit from base classes. Polymorphism allows the same message to be interpreted differently, and message passing facilitates communication between objects.

Design patternsBinu Bhasuran

Design patterns are commonly used to address problems relating to application architecture and design. The concept originated from Christopher Alexander's work noting common building design problems and solutions. Design patterns ensure problems are addressed through well-known solutions, and most problems have likely been solved before. Common patterns include observer/subject to separate user interface from business logic, singleton to control object construction, strategy to allow multiple algorithms, and template method to define an algorithm's structure. The facade pattern provides different views of subsystems to users by hiding implementation details. The command pattern encapsulates requests as objects with a known interface to decouple senders and receivers.

L03 Software DesignÓlafur Andri Ragnarsson

This document discusses object-oriented programming concepts like classes, inheritance, and polymorphism. It begins with an overview of classes, explaining that classes contain instance variables and methods. Classes can extend other classes through inheritance, allowing subclasses to override or add new functionality. References can point to objects of a class or any superclass. The document then discusses polymorphism, where the decision of which method to call is determined at runtime based on the actual object type. This allows subclasses to be used through their parent class references. The summary cautions that direct concrete inheritance can cause issues if not used carefully, such as violating the Liskov substitution principle.

To better understand the behavior of servlets, let’s take a look at the life cycle of servlets. A servlet is basically a small Java program that runs within a Web server. It can receive requests from clients and return responses. The whole life cycle of a servlet breaks up into 3 phases: • Initialization: A servlet is first loaded and initialized usually when it is requested by the corresponding clients. Some websites allow the users to load and initialize servlets when the server is started up so that the first request will get responded more quickly. • Service: After initialization, the servlets serve clients on request, implementing the application logic of the web application they belong to. • Destruction: When all pending requests are processed and the servlets have been idle for a specific amount of time, they may be destroyed by the server and release all the resources they occupy. More specifically, the behavior of a servlet is described in javax.servlet.Servlet interface, in which the following methods are defined: • public void init(ServletConfig config) throws ServletException This method is called once when the servlet is loaded into the servlet engine, before the servlet is asked to process its first request. The init method has a ServletConfig parameter. The servlet can read its initialization arguments through the ServletConfig object. How the initialization arguments are set is servlet engine dependent but they are usually defined in a configuration file. A typical example of an initialization argument is a database identifier. A servlet can read this argument from the ServletConfig at initialization and then use it later to open a connection to the database during processing of a request: private String databaseURL; public void init(ServletConfig config) throws ServletException { super.init(config); databaseURL = config.getInitParameter("database"); } • public void service(ServletRequest request, ServletResponse response) throws ServletException, IOException This method is called to process a request. It can be called zero, one or many times until the servlet is unloaded. Once a servlet is loaded, it remains in the server’s memory as a single object instance. Thereafter, the server invokes the servlet to handle a request using a simple, lightweight method invocation. Unlike with CGI, there’s no process to spawn or interpreter to invoke, so the servlet can begin handling the request almost immediately. Multiple, concurrent requests are handled by separate threads, so servlets are highly scalable. Servlets are naturally enduring objects. Because a servlet stays in the server’s memory as a single object instance, it automatically maintains its state and can hold on to external resources, such as database connections, that may otherwise take several seconds to establish. The following servlet presents information about how many times it has been accessed: To better understand the behavior of servlets, let’s take a lo

CssArmy Public School and College -Faisal

CSS (Cascading Style Sheets) allows separation of document content from document presentation by defining styles like fonts, colors, spacing in external .css files or internal <style> tags. CSS selectors target HTML elements by name, id, class, or attribute to style them. Styles can be defined externally, internally, or inline. When multiple conflicting styles apply, the cascade order gives precedence to inline styles, then internal and external styles, and lastly browser defaults.

Polymorphism (2)Army Public School and College -Faisal

This document discusses polymorphism in C# through method overloading and overriding. It shows how to create a base DrawingObject class that can be inherited by Line, Circle, and Square classes, where each subclass overrides the Draw method to output its type. The Main method creates instances of each subclass and calls their Draw methods to demonstrate polymorphism. The document also compares abstract classes and interfaces, noting that abstract classes can contain implemented methods while interfaces only contain signatures, and interfaces allow multiple inheritance while abstract classes do not.

Constants refer to fixed values that cannot be altered during program execution. They include integer, floating point, character, and string literals. Constants are defined using the #define preprocessor or const keyword and are treated like regular variables except their values cannot change. Common operators in C include arithmetic, relational, logical, and bitwise operators that perform math, comparison, logic and bit manipulation functions.

Object Oriented Programming

1. Advance Concepts of Object Oriented Design

3. Objectives • Design principles of Object Oriented Programming • Pillars of Object Oriented Programming Concept of Object Oriented Design The process of planning a system of interacting objects for the purpose of solving a software problem .it is one of the approaches for software design

4. Object Oriented programming Object Oriented programming (OOP) is a programming paradigm that represents concepts as “objects "that have data fields (attributes that describe the object) and associates procedures known as methods. Objects ,which are instances of classes ,are used to interact with one another to design applications and computer programs Examples of Object Oriented languages include Smalltalk C++ and objective-c Eiffel .Python ,Ruby java C# Visual Basic .NET

5. Pillars of Object Oriented Programming Inheritance one of the primary concepts of object-oriented programming.it allows you to reuse existing code, through effective employment of reuse you can save time in your programming

6. Using System; public class Parent Class { public Parent Class() { Console.WriteLine(“Parent Constructor”); } public void print() { Console.WriteLine(“I am parent class ”); } } Public Child Class :Parent Class public Child Class() { Console.WriteLine(“Child Constructor ”); } } Public static void main () { Child Class child = new Child Class(); child.print(); } } The top class is named as parent class and the main class is called child class, what we want to do is create a child class as the base class of child class . This is accomplished through the child class declaration as public class. the base class is specified by adding a colon “:”; after the derived class identifier and then specifying the base class name .

7. Sealed Class Sealed Classes are used to restrict the inheritance feature of object oriented programming once a class is defined as sealed class this class cannot be inherited Encapsulation Encapsulation is the process of putting data and the operations (functions) that can be performed on data into a single container called class Now any programmer can use this class without knowing how is implemented .Due to encapsulation data is insulated thus not directly accessible from the outside world ,this is known as data hiding Encapsulation is not data hiding but Encapsulation leads to data hiding Access Modifier Access modifier are keywords used to specify the declared accessibility of a member or a type .This section introduces the four access modifiers

8. Public The public keyword is an access modifier for types and type members. Public access is the most permissive access level there are no restriction accessing public members Using system class bank account Public { public decimal Get Amount() { return 1000.00m; } }

9. Using system class MyClass { protected int x; protected int y; } class My DerivedC:MyClass { public static void main() { MyDerived mC=new My DerivedC(); // Direct access to protected members: mC.x = 10; mC.y = 15; Console.WriteLine(“ x = {0}, y = {1} ”. mC.x. mC,y); } }

10. Private Private keyword is a member access modifier .A Private member is least permissive access level .Private member are accessible within the body of the class Using System class Bank Account Private { private string m_name ; public string Customer Name { get { get { return m_name;} set{ m_name = value;} } }

11. Internal The Internal keyword is a member access modifier for types and type members A Internal member are accessible from with in the files in the same assembly
