Object oriented programming
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.

SE-IT JAVA LAB OOP CONCEPT
SE-IT JAVA LAB OOP CONCEPTnikshaikh786 1. Object oriented programming (OOP) is a programming paradigm that models concepts as "objects" that contain data and functionality.
2. A class defines the format for objects, including attributes like properties and behaviors like methods. Creating an object from a class is like a real-world object.
3. OOP concepts like encapsulation, inheritance, and polymorphism address limitations of procedural programming by combining related data and functions into classes and objects. Encapsulation wraps data and functions together, hiding implementation details.

It defines procedural programming as step-by-step instructions telling a computer what to do, with languages like C, Go, and BASIC given as examples. Modular programming is described as separating a program into independent modules. The difference between procedural and modular programming is that procedural follows an algorithm, while modular divides the objective into pipelined modules. Object-oriented programming concepts covered include objects and classes as logical entities, encapsulation as wrapping data and methods, abstraction as exposing only essential characteristics, inheritance as creating new classes from existing ones, and polymorphism as having many forms in a hierarchy with inheritance.

It discusses how OOP involves writing programs based on objects, and defines a class as a group of objects that share attributes and behaviors. An object is an instance of a class that contains all the variables and functions of that class. Key characteristics of OOP discussed include inheritance, data abstraction, encapsulation, and polymorphism. Inheritance allows new classes to inherit properties from existing classes. Data abstraction hides background details and simplifies development. Encapsulation binds data to the functions that operate on it.

Basics of Object Oriented ProgrammingAbhilash Nair Here are the key concepts of Object Oriented Programming:
- Object: An object represents a real world entity with attributes and behaviors. Ex: Person, Bank Account etc.
- Class: A class defines the common attributes and behaviors of objects. It acts as a blueprint to create objects.
- Encapsulation: Wrapping up of data and methods into a single unit called class. It hides internal details and represents as a single unit.
- Inheritance: Ability to create new classes from existing classes by extending their features. New classes inherit attributes and behaviors of parent classes.
- Polymorphism: Ability of an object to take multiple forms. Same method can act differently depending on the object that inv

Chapter 6 OOPS Concept
Chapter 6 OOPS ConceptAmrit Kaur Object oriented programming views a system as a collection of objects that contain both data (state) and behaviors (operations). An object has an identity, state, and behavior. Classes are sets of similar objects that share common attributes and behaviors. The key characteristics of object oriented programming are abstraction, encapsulation, inheritance, and polymorphism. Abstraction involves hiding non-essential details and focusing on essential characteristics. Encapsulation implements abstraction by hiding implementation details within an object. Inheritance allows new classes to inherit and modify attributes and behaviors from existing classes. Polymorphism means an object can behave differently under different circumstances.

Oops
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.
Oops
OopsMaheswarikrishnasamy OOPs concepts include objects, classes, encapsulation, inheritance, and polymorphism. Objects are run-time entities that can access class data through associated methods. Classes are user-defined data types that implement abstraction and encapsulation. Encapsulation provides an interface between an object's data and the program. Inheritance allows classes to inherit properties from superclasses and subclasses. Polymorphism allows an object to take different forms depending on its data type. Constructors initialize objects and destructors finalize them. OOPs benefits applications by building secure, modularized programs that are reusable and allow interference-free object coexistence.

Constructor & Destructor
Constructor & DestructorKV(AFS) Utarlai, Barmer (Rajasthan) This document discusses constructors and destructors in C++. It defines a constructor as a special member function with the same name as the class that is used to initialize objects. Constructors are called automatically when objects are created and allow objects to be initialized before use. Constructors cannot be inherited or static and default and copy constructors are generated by the compiler. The document also discusses declaration, default arguments, copy constructors, and the order of constructor invocation.
Classes and objects
Classes and objectsShailendra Veeru The document discusses structures and classes in C++. It explains that structures in C++ allow grouping of related data items but do not provide data hiding. Classes in C++ address this limitation by allowing data and functions as members, and designating some members as private. The key aspects of a class include its declaration with data and function members, creation of objects from the class, and accessing members using objects and dot operator (for public members) or within class functions (for private members). Static members are also discussed which are shared among all class objects.

Constructor & destructor
Constructor & destructorSaharsh Anand - Constructors are special member functions used to initialize objects when they are created. They are automatically called upon object creation and have the same name as the class. Constructors can be default, parameterized, or copy constructors.
- Destructors are also special member functions that perform cleanup actions when an object is destroyed, such as freeing memory. They are called automatically upon object destruction and have the same name as the class preceded by a tilde.
- Examples demonstrate default, parameterized, and copy constructors as well as destructors being defined and called for a class to properly initialize and cleanup objects.

YSPH VMOC Special Report - Measles Outbreak Southwest US 5-3-2025.pptxYale School of Public Health - The Virtual Medical Operations Center (VMOC) A measles outbreak originating in West Texas has been linked to confirmed cases in New Mexico, with additional cases reported in Oklahoma and Kansas. The current case count is 817 from Texas, New Mexico, Oklahoma, and Kansas. 97 individuals have required hospitalization, and 3 deaths, 2 children in Texas and one adult in New Mexico. These fatalities mark the first measles-related deaths in the United States since 2015 and the first pediatric measles death since 2003.
The YSPH Virtual Medical Operations Center Briefs (VMOC) were created as a service-learning project by faculty and graduate students at the Yale School of Public Health in response to the 2010 Haiti Earthquake. Each year, the VMOC Briefs are produced by students enrolled in Environmental Health Science Course 581 - Public Health Emergencies: Disaster Planning and Response. These briefs compile diverse information sources – including status reports, maps, news articles, and web content– into a single, easily digestible document that can be widely shared and used interactively. Key features of this report include:
- Comprehensive Overview: Provides situation updates, maps, relevant news, and web resources.
- Accessibility: Designed for easy reading, wide distribution, and interactive use.
- Collaboration: The “unlocked" format enables other responders to share, copy, and adapt seamlessly. The students learn by doing, quickly discovering how and where to find critical information and presenting it in an easily understood manner.

In fact, Gopal was elected to the throne only to end Matsya Nyaya. Bhagalpur Abhiledh states that Dharmapala imposed only fair taxes on the people. Rampala abolished the unjust taxes imposed by Bhima. The Pala rulers were lovers of learning. Vikramshila University was established by Dharmapala. He opened 50 other learning centers. A famous Buddhist scholar named Haribhadra was to be present in his court. Devpala appointed another Buddhist scholar named Veerdeva as the vice president of Nalanda Vihar. Among other scholars of this period, Sandhyakar Nandi, Chakrapani Dutta and Vajradatta are especially famous. Sandhyakar Nandi wrote the famous poem of this period 'Ramcharit'.

CBSE - Grade 8 - Science - Chemistry - Metals and Non Metals - Worksheet
CBSE - Grade 8 - Science - Chemistry - Metals and Non Metals - WorksheetSritoma Majumder Introduction
All the materials around us are made up of elements. These elements can be broadly divided into two major groups:
Metals
Non-Metals
Each group has its own unique physical and chemical properties. Let's understand them one by one.
Physical Properties
1. Appearance
Metals: Shiny (lustrous). Example: gold, silver, copper.
Non-metals: Dull appearance (except iodine, which is shiny).
2. Hardness
Metals: Generally hard. Example: iron.
Non-metals: Usually soft (except diamond, a form of carbon, which is very hard).
3. State
Metals: Mostly solids at room temperature (except mercury, which is a liquid).
Non-metals: Can be solids, liquids, or gases. Example: oxygen (gas), bromine (liquid), sulphur (solid).
4. Malleability
Metals: Can be hammered into thin sheets (malleable).
Non-metals: Not malleable. They break when hammered (brittle).
5. Ductility
Metals: Can be drawn into wires (ductile).
Non-metals: Not ductile.
6. Conductivity
Metals: Good conductors of heat and electricity.
Non-metals: Poor conductors (except graphite, which is a good conductor).
7. Sonorous Nature
Metals: Produce a ringing sound when struck.
Non-metals: Do not produce sound.
Chemical Properties
1. Reaction with Oxygen
Metals react with oxygen to form metal oxides.
These metal oxides are usually basic.
Non-metals react with oxygen to form non-metallic oxides.
These oxides are usually acidic.
2. Reaction with Water
Metals:
Some react vigorously (e.g., sodium).
Some react slowly (e.g., iron).
Some do not react at all (e.g., gold, silver).
Non-metals: Generally do not react with water.
3. Reaction with Acids
Metals react with acids to produce salt and hydrogen gas.
Non-metals: Do not react with acids.
4. Reaction with Bases
Some non-metals react with bases to form salts, but this is rare.
Metals generally do not react with bases directly (except amphoteric metals like aluminum and zinc).
Displacement Reaction
More reactive metals can displace less reactive metals from their salt solutions.
Uses of Metals
Iron: Making machines, tools, and buildings.
Aluminum: Used in aircraft, utensils.
Copper: Electrical wires.
Gold and Silver: Jewelry.
Zinc: Coating iron to prevent rusting (galvanization).
Uses of Non-Metals
Oxygen: Breathing.
Nitrogen: Fertilizers.
Chlorine: Water purification.
Carbon: Fuel (coal), steel-making (coke).
Iodine: Medicines.
Alloys
An alloy is a mixture of metals or a metal with a non-metal.
Alloys have improved properties like strength, resistance to rusting.
APM Midlands Region April 2025 Sacha Hind Circulated.pdf
APM Midlands Region April 2025 Sacha Hind Circulated.pdfAssociation for Project Management APM event hosted by the Midlands Network on 30 April 2025.
Speaker: Sacha Hind, Senior Programme Manager, Network Rail
With fierce competition in today’s job market, candidates need a lot more than a good CV and interview skills to stand out from the crowd.
Based on her own experience of progressing to a senior project role and leading a team of 35 project professionals, Sacha shared not just how to land that dream role, but how to be successful in it and most importantly, how to enjoy it!
Sacha included her top tips for aspiring leaders – the things you really need to know but people rarely tell you!
We also celebrated our Midlands Regional Network Awards 2025, and presenting the award for Midlands Student of the Year 2025.
This session provided the opportunity for personal reflection on areas attendees are currently focussing on in order to be successful versus what really makes a difference.
Sacha answered some common questions about what it takes to thrive at a senior level in a fast-paced project environment: Do I need a degree? How do I balance work with family and life outside of work? How do I get leadership experience before I become a line manager?
The session was full of practical takeaways and the audience also had the opportunity to get their questions answered on the evening with a live Q&A session.
Attendees hopefully came away feeling more confident, motivated and empowered to progress their careers

Object oriented programming
- 2. Name Muhammd Umair Sajjad Roll No 531 Department BS(CS)(Evening) Submitted to Mam Uswa Farooq Submission date 16-06-2020 Govt. P/G Islamia College Faisalabad
- 3. 13.1 OBJECT ORIENTED PROGRAMMING :- Object-Oriented programming (OOP) is a programming technique or method in which we design a program by using objects and classes. OBJECTS LIVING THINGS HUMAN ANIMALS NON LIVING THINGS EACH ITEM INCLUDE CAR,DESK,TABLE etc.
- 4. :- An object is an entity that consists of data and functions :- c++ and java are the example of object oriented language
- 5. FEATURES •Objects:- Object oriented programming is based on object. An object is an entity that is shown in fig. • Classes:- Classes are designs for creating objects. In classes we see what is private and what is public. • Real-world Modeling:- It is based in real-world modeling. Entities have different properties and capabilities in real world.
- 6. FEATURES • Reuseability:- We make function one time and use many time. • Information Hiding:- We show only those data that we want to show the user. • Polymorphism:- Ability of object behave in multiple way.
- 7. 13.2 OBJECTS • Properties:- Characteristics of an object Example:- Properties of a car is • Color • Price • Model • Engine Power • Functions:- It is the action performed by an object Example:- Functions of a car is • Start • Stop • Accelerate • Reverse
- 8. 13.3 ClASSES :- A group of object with same properties. :- Use as a model to create same type object. :- Use to define the characteristics and function of object. Declaring:- Keyword class is used to declare classs which specifies variables and functions that are common to all objects of class. Access Specifiers:- A command use to specify access level of the class member •
- 9. Access Specifiers:- Private • It can only access within the class Public • It can access anywhere in the program
- 10. 13.4 CREATING OBJECTS :- A class is prototype for creatin object :- Process of creating an object of class called instantiation Executing Member Function:- • The member function can be executed after creating an object. Defining Member Function outside Class:- • The declaration of member function specified within class. • If define function outside we use resolution operator (::).
- 11. 13.5 CONSTRUCTORS :- The member function has same name as class called constructor. Constructor cannot return any value :- Use to initialize data member in the class. Passing Parameters to Constructor:- The parameters are written in parenthesis along with the object name in declaration statement. Constructor Overloading:- When we declare multiple constructors with same name but different parameters we called this constructor overloading.
- 12. 13.6 DEFAULT COPY CONSTRUCTOR :- A constructor which is available by default in all classes. :- We give parameters in parenthesis or using assignment operator.
- 13. 13.7 DECONSTRUCTOR :- A type of member function that is automatically executed when an object of that class is destroyed is known as destructor. :- Return no value :- Cannot accept any parameter :- Nmae is precede by sign (~)
- 14. 13.8 OBJECT AS FUNCTION PARAMETERS :- We can be passed object as parameter to member function Returning Objects from Member Function:- The method of returning an object from member function is same as returning a simple variable
- 15. 13.9 STATIC DATA MEMBER :- A data member type that is shared among all objects of class :- Define with static keyword :- Characteristics of a static data member are same as normal static variable
- 16. 13.10 FRIENDS FUNCTION :- A function that allow to access the private and protected members of a particular class from outside the class. :- Normally private and protected member of any cannot be accessed from outside the class. :- It enable the function to access the private and protected members of Both
