Encapsulation involves bundling data members and functions inside a class to help with data hiding and ensure objects work independently. It wraps both data and methods into a single unit so end-users only need to provide inputs and receive outputs. Encapsulation provides well-defined, readable code; prevents accidental modification; and provides security. Python supports public, private, and protected access modifiers to restrict access to variables and functions within and outside classes.

Chapter 07 inheritance
1. Inheritance is a mechanism where a new class is derived from an existing class, known as the base or parent class. The derived class inherits properties and methods from the parent class.
2. There are 5 types of inheritance: single, multilevel, multiple, hierarchical, and hybrid. Multiple inheritance allows a class to inherit from more than one parent class.
3. Overriding allows a subclass to replace or extend a method defined in the parent class, while still calling the parent method using the super() function or parent class name. This allows the subclass to provide a specific implementation of a method.
Packages in java
Packages in Java allow grouping of related classes and interfaces to avoid naming collisions. Some key points about packages include:
- Packages allow for code reusability and easy location of files. The Java API uses packages to organize core classes.
- Custom packages can be created by specifying the package name at the beginning of a Java file. The class files are then compiled to the corresponding directory structure.
- The import statement and fully qualified names can be used to access classes from other packages. The classpath variable specifies locations of package directories and classes.
Polymorphism presentation in java
Polymorphism in Java allows an object to take on multiple forms. There are two types of polymorphism: compile-time polymorphism (method overloading) and runtime polymorphism (method overriding). Method overloading involves methods with the same name but different parameters, while method overriding involves subclasses providing their own implementation of a superclass method. Runtime polymorphism determines which version of a method to call based on the object's actual type at runtime. Abstraction in Java allows hiding implementation details and showing only essential functionality through the use of abstract classes and methods.

Python Inheritance , Single Inheritance,Multiple Inheritance,Multilevel Inheritance,Hierachical Inheritance
Inheritance C#
Inheritance allows one class to inherit properties and behaviors from another base class. There are two main types of inheritance: implementation inheritance, where a derived class takes on all members of the base class; and interface inheritance, where a derived class inherits only function signatures without implementations. Key aspects of inheritance in C# include defining virtual methods that can be overridden, using modifiers like sealed to restrict inheritance, and implementing interfaces that define common behaviors without implementations.
Classes, objects in JAVA
This document discusses classes, objects, and methods in Java. It defines a class as a user-defined data type that contains fields and methods. Objects are instances of classes that allocate memory at runtime. Methods define behaviors for objects and are declared within classes. The document covers defining classes, creating objects, accessing members, constructors, method overloading and overriding, static members, passing objects as parameters, recursion, and visibility control.
Python: Basic Inheritance
The document discusses basic inheritance in Python. It explains that all classes inherit from the base Object class. Inheritance allows creating subclasses that inherit attributes and methods from a parent superclass. This allows code reuse and adding specialized behavior. An example creates a Contact class to store names and emails, with a Supplier subclass that adds an "order" method. A SupplierCheck subclass then overrides the order method to check the customer balance before processing orders.
Inheritance in java
This document discusses implementation of inheritance in Java and C#. It covers key inheritance concepts like simple, multilevel, and hierarchical inheritance. It provides examples of inheritance in Java using keywords like extends, super, this. Interfaces are discussed as a way to achieve multiple inheritance in Java. The document also discusses implementation of inheritance in C# using concepts like calling base class constructors and defining virtual methods.
java interface and packages
An interface in Java is a blueprint of a class that defines static constants and abstract methods. Interfaces are implemented by classes where they inherit the properties and must define the body of the abstract methods. Key points are:
- Interfaces can only contain abstract methods and static constants, not method bodies.
- Classes implement interfaces to inherit the properties and must define the abstract method bodies.
- An interface can extend other interfaces and a class can implement multiple interfaces.
Files in java
The document discusses different types of streams in Java including file, byte, character, and standard streams. File streams allow reading and writing of files and include classes like FileInputStream and FileOutputStream for bytes and FileReader and FileWriter for characters. Byte streams handle 8-bit bytes while character streams handle 16-bit Unicode. Standard streams in Java are System.in for input, System.out for standard output, and System.err for errors. Sample code is provided to write to and read from files.
Inheritance in JAVA PPT
This document discusses inheritance in object-oriented programming. It defines inheritance as establishing a link between classes that allows sharing and accessing properties. There are three types of inheritance: single, multilevel, and hierarchical. Single inheritance involves one parent and one child class, multilevel inheritance adds intermediate classes, and hierarchical inheritance has one parent and multiple child classes. The document provides examples of inheritance code in Java and demonstrates a program using inheritance with interfaces. It notes some limitations of inheritance in Java.
[OOP - Lec 19] Static Member Functions
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.
Basic concept of OOP's
Object oriented programming is a modular approach to programming that treats data and functions that operate on that data as objects. The basic elements of OOP are objects, classes, and inheritance. Objects contain both data and functions that operate on that data. Classes are templates that define common properties and relationships between objects. Inheritance allows new classes to acquire properties of existing classes. OOP provides advantages like modularity, code reuse, and data abstraction.
Polymorphism In c++
This document discusses polymorphism in C++. It defines polymorphism as the ability for functions or operators to have different meanings depending on the context. It describes different types of polymorphism including static and dynamic polymorphism. It then provides examples of method overloading, operator overloading, and virtual functions to illustrate polymorphism concepts in C++.
CLASS OBJECT AND INHERITANCE IN PYTHON
This document discusses classes, objects, and inheritance in Python. It defines a class as a blueprint for creating objects, with objects being instances of a class. It describes how to define a class in Python using the class keyword and how to create object instances from a class. The document also explains inheritance in Python, where a derived or child class can inherit attributes and methods from a parent or base class, allowing for single, multiple, multilevel, hybrid and hierarchical inheritance.
C++ OOPS Concept
The document discusses the key concepts of object-oriented programming (OOP) in C++, including objects, classes, abstraction, encapsulation, inheritance, polymorphism, overloading, and exception handling. Objects are instances of classes that contain data members and member functions. Classes define the blueprint for objects and allow data and functions to be bundled together. Abstraction hides unnecessary details and focuses on essential information. Encapsulation binds data and functions together within a class. Inheritance allows code reuse through deriving a new class from an existing class. Polymorphism and overloading allow functions to operate on different data types. Exception handling manages errors at runtime.
Polymorphism in Python
In programming, polymorphism means the same function name (but different signatures) being used for different types.
Vectors in Java
The program accepts 5 items from the command line and stores them in a Vector. It then demonstrates deleting an item, adding an item at a specified position, adding an item at the end, and printing the Vector contents. The Vector implements a dynamic array that can hold any type of objects and any number of elements. It is contained in the java.util package and is synchronized.
virtual function
Virtual functions allow functions to be overridden in derived classes. The virtual keyword before a function in the base class specifies that the function can be overridden. When a virtual function is called using a base class pointer, the version from the most derived class will be executed due to late binding. This allows runtime polymorphism where the function call is resolved based on the actual object type rather than the pointer variable type.
Encapsulation C++
The document discusses encapsulation in object-oriented programming. It defines encapsulation as combining data and functions into a single unit called a class, with data only accessible through class functions. This provides secure and consistent results by hiding implementation details and restricting access. An example C++ program demonstrates encapsulation by defining a class with private data members that can only be accessed and modified through public member functions. The advantages of encapsulation include easier application maintenance, improved understandability, and enhanced security.
Python-DataAbstarction.pptx
Data abstraction is the process of hiding unnecessary implementation details and exposing only essential information to the user. It separates the interface from the implementation. In Python, data abstraction can be achieved through abstract classes, which cannot be instantiated directly but can be inherited. Abstract classes define a common API for subclasses and allow concrete methods to be implemented only once for all subclasses. Data abstraction improves flexibility, reusability, and makes working on large codebases with teams easier.
Java packages
Packages in Java are used to organize classes and provide namespace management to avoid naming conflicts. A package groups related types like classes, interfaces, enums and annotations. Programmers can define their own packages to organize related classes. Packages create a new namespace to avoid conflicts and make classes easier to locate and access. The package name is specified in a source file using the package keyword and files for a package must be stored in a subdirectory matching the package name. Classes in other packages can be accessed using their fully qualified names or by importing the package.
Lecture 8
The document discusses object-oriented programming concepts like classes, objects, encapsulation, inheritance and polymorphism. It explains that OOP provides modularity and code reuse through techniques like inheritance and polymorphism. A class defines the blueprint for an object by encapsulating its state as member variables and behavior as methods. The document outlines class members like fields, methods and constructors. It also covers access modifiers, static and final modifiers for classes and members.
What is OOP_ (Object Oriented Programming) (1).pptx
Object oriented programming (OOP) is a programming model that organizes software around objects and classes rather than functions and logic. There are four main concepts in OOP: encapsulation, modularity, polymorphism, and inheritance. Encapsulation bundles data and methods into a single unit, modularity splits programs into independent and interchangeable modules, polymorphism allows objects to take on multiple forms, and inheritance allows classes to derive properties from parent classes. The shift from procedural to OOP allowed for more reusable, flexible, and maintainable code.

Object-Oriented Programming in Java
Java is a well-liked programming language that may be used to create a wide range of applications, from straightforward desktop programs to intricate web programs. It is an object-oriented programming language that enables programmers to create modular, reusable code, making it simple to maintain and update.
We shall look at the fundamentals of Java object-oriented programming in this tutorial. The fundamentals of object-oriented programming in Java, oops concepts such as classes and objects, inheritance, polymorphism, and encapsulation will all be covered. You will have a solid understanding of object-oriented programming in Java and how to use it to create robust and scalable programs at the end of this article.
Introduction to OOPs concept
Object-oriented programming in Java is a programming paradigm that revolves around objects. An object is a real-world entity that has a set of attributes and behaviors. In Java, even basic data types like integers and booleans are considered objects.
In OOPS, a program is designed by creating objects that interact with each other to perform tasks. Objects have attributes that define their properties and methods that define their behavior.
In Java, we create classes, which are templates that define the attributes and behaviors of objects. A class can be compared to an object creation blueprint. Once a class is defined, objects can be created based on that class.
Principles of Object-Oriented Programming
There are four main principles of object-oriented programming:
a. Abstraction
Abstraction is the process of hiding complex details and providing a simplified interface for the user. It helps developers to create simpler and more understandable models of a complex system, by just exposing only the required features and not the implementation part. In Java, abstraction can be achieved using interfaces and abstract classes.
b. Encapsulation
Encapsulation is the process of hiding the internal details of an object and providing a public interface for accessing and modifying the object. It helps in maintaining the integrity of the object and ensures that its internal state cannot be modified by external code. In Java, encapsulation can be achieved using access modifiers such as public, private, and protected.
Got confused between Abstraction and Encapsulation?
Abstraction is about simplifying the complexity of a system by focusing on its essential features, while encapsulation is about protecting the integrity of an object by hiding its internal details.
c. Inheritance
The process of creating a new class from an existing one is called Inheritance. The new class inherits the attributes and behaviors of the existing class and can add additional attributes and behaviors. This helps in reducing code duplication, promoting code reuse, and making the code more modular and maintainable. In Java, the extend keyword is useful for achieving inheritance.
d. Polymorphism
The ability of an
Reflection in Java
Reflection in Java allows a program to access and manipulate its own structure, behavior, and configuration at runtime. It works by storing metadata about classes, fields, methods and constructors that can then be accessed dynamically. The key advantages are signature-based polymorphism, inspecting and manipulating classes flexibly without knowing their structure at compile-time. However, reflection is slower than direct code and exposes implementation details, posing some security risks.
Java questions for interview
- Java is a high-level programming language originally developed by Sun Microsystems and released in 1995. It runs on a variety of platforms such as Windows, Mac OS, and UNIX.
- The Java Virtual Machine (JVM) allows Java code to run on different platforms, as the bytecode is interpreted by the JVM rather than being compiled into platform-specific machine code.
- Some key features of Java include being object-oriented, platform independent, robust, interpreted, and multi-threaded.
Features of Object Oriented Programming.pptx
This document discusses the key features of object-oriented programming in Java, including classes, objects, inheritance, encapsulation, abstraction, and polymorphism. It provides examples of each concept: classes define templates for objects, objects are instances of classes with state and behavior, inheritance allows subclasses to inherit properties and behaviors from parent classes, encapsulation binds data and code together restricting access, abstraction hides implementation details and exposes only necessary information, and polymorphism allows treating objects of different classes as common superclasses. The document is written by Swagato Biswas for a course on object-oriented programming.
"Study of Java Access Control Mechanism”
Abstract: a class as "a collection of data and methods." One of the important object-oriented techniques is
hiding the data within the class and making it available only through the methods. This technique is known as
encapsulation because it seals the data (and internal methods) safely inside the "capsule" of the class, where it
can be accessed only by trusted users.
Another reason for encapsulation is to protect your class against accidental or willful stupidity. A class
often contains a number of interdependent fields that must be in a consistent state. If you allow a users to
manipulate those fields directly, he may change one field without changing important related fields, thus leaving
the class in an inconsistent state. If, instead, he has to call a method to change the field, that method can be sure
to do everything necessary to keep the state consistent. Similarly, if a class defines certain methods for internal
use only, hiding these methods prevents users of the class from calling them.
The goal is : All the fields and methods of a class can always be used within the body of the class itself. Java
defines access control rules that restrict members of a class from being used outside the class that is done
through keeping the data (and internal methods) safely inside the "capsule" of the class, where it can be
accessed only by trusted users.

EEE oops Vth semester viva questions with answer
1. An object is the basic unit of object-oriented programming and represents an instance of a class. Objects have unique names and can hold their own data.
2. A class defines a collection of similar objects. Instances are objects created from classes through a process called instantiation.
3. Object-oriented programming organizes programs around objects and a set of well-defined interfaces to access object data. Data is encapsulated within classes and accessed through member functions.

This document discusses data hiding and data abstraction in Python. It defines data hiding as hiding implementation details from users by declaring class members as private using double underscores. Data hiding enhances security and prevents linking to wrong data. The document also defines abstract classes as blueprints that require child classes to implement abstract methods, allowing a common API. Abstract classes in Python can contain both concrete and abstract methods, and concrete classes provide implementations of abstract methods.

Encapsulation treats an object's data and methods as a single unit, inheritance creates class hierarchies where subclasses inherit attributes and behaviors from parent classes, and polymorphism allows the same method to work differently for different classes. The main building blocks are classes, which act as templates for objects, and methods, which define objects' behaviors.
Oops concepts
This document provides an overview of object-oriented programming concepts. It begins by defining a programming language and different levels of abstraction in languages. It then defines object-oriented programming as relying on classes and objects, with classes acting as blueprints for objects. The basic building blocks of OOP - objects, classes, attributes, and methods - are introduced. Each concept is then defined in more detail, including objects, classes, inheritance, encapsulation, abstraction, and polymorphism. The document concludes by outlining some advantages of using an object-oriented programming approach.
Oop ppt
This document discusses object-oriented programming (OOP) concepts in Java such as classes, objects, inheritance, encapsulation, abstraction, and polymorphism. It defines OOP as a programming paradigm that uses classes and objects. Key concepts covered include how objects represent real-world entities with variables and methods, how classes define object types, and how inheritance, encapsulation, and polymorphism are implemented in Java. Examples are provided to illustrate constructor, inheritance, and polymorphism.
Unit-4 Day1.pptx
This document discusses abstraction and encapsulation in Scala. It defines abstraction as hiding internal details and showing only functionality. Abstraction can be achieved through abstract classes and interfaces/traits. Abstract classes can contain abstract and non-abstract methods, while interfaces contain only abstract methods. The document also discusses packages, which provide namespaces, and access modifiers like private, protected, and public, which restrict access to class members.
Oops abap fundamental
This document provides an overview of object-oriented programming concepts in ABAP, including classes, objects, inheritance, polymorphism, abstraction, and encapsulation. It defines key concepts such as class, object, attributes, methods, visibility, and instances. Classes contain attributes and methods, and objects are instances of classes with their own attributes. Inheritance allows classes to acquire properties of parent classes, while polymorphism allows methods to behave differently in different classes. Abstraction hides internal details and encapsulation binds code and data together.
Object oriented basics
The document discusses object orientation and compares procedural and object-oriented programming. It defines key concepts in object-oriented programming like classes, objects, inheritance, encapsulation, and polymorphism. It also provides an example of a local class in ABAP with methods to retrieve and display data from database tables.

Python-FileHandling.pptx
File handling in Python allows programs to work with files stored on disk by performing operations like opening, reading, writing, and modifying files. The open() function is used to open a file and return a file object, which can then be used to read or write to the file. There are different file access modes like 'r' for read-only, 'w' for write-only, and 'a' for append. Common methods for reading files include read() to read characters, readline() to read one line, and readlines() to read all lines into a list. Files can be written to using write() and writelines() methods and deleted using functions in the os, shutil, or pathlib modules.
Python-exceptionHandling.pptx
Syntax errors occur due to incorrect syntax and terminate the program, while exceptions are raised when code is syntactically correct but results in an error, changing normal program flow without terminating. Try and except statements are used to catch and handle exceptions in Python by keeping exception-raising code in the try clause and exception handling code in except clauses, and can specify different handlers for different exceptions. The else clause runs if no exceptions occur in the try block.
Overloading vs Overriding.pptx
Method overloading allows defining methods with the same name but different parameters in one class, but Python does not support it as everything is an object - it uses the latest defined method. Method overriding defines a method in a child class that has the same name, parameters and return type as a parent class method, overriding the parent's implementation at runtime for polymorphism.
Python-Polymorphism.pptx
Polymorphism refers to a function having the same name but being used in different ways and different scenarios, making programming easier and more intuitive. Polymorphism is a fundamental concept in object-oriented programming that allows one function to display multiple functionalities through inheritance, where a child class inherits all methods from the parent class. In Python, polymorphism can be implemented through classes having different methods with the same name, inheritance where child classes can override parent methods, and by defining functions that can accept different object types.
Python-Classes.pptx
Object-oriented programming (OOP) organizes code around data objects rather than functions. In Python, classes are user-defined templates for objects that contain attributes (data) and methods (functions). When a class is instantiated, an object is created with its own copies of the attributes. Self refers to the object itself and allows methods to access and modify its attributes. Classes in Python allow for code reusability, modularity, and flexibility through encapsulation, inheritance, and polymorphism.
Python-Functions.pptx
Functions allow programmers to organize and reuse code. They take in parameters and return values. Parameters act as variables that represent the information passed into a function. Arguments are the actual values passed into the function call. Functions can have default parameter values. Functions can return values using the return statement. Python passes arguments by reference, so changes made to parameters inside functions will persist outside the function as well. Functions can also take in arbitrary or keyword arguments. Recursion is when a function calls itself within its own definition. It breaks problems down into sub-problems until a base case is reached. The main types of recursion are direct, indirect, and tail recursion. Recursion can make code more elegant but uses more memory than iteration.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Applications of artificial Intelligence in Mechanical Engineering.pdf
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

Python-Encapsulation.pptx
- 2. Basics about Encapsulation? Encapsulation is one of the critical features of object-oriented programming, which involves the bundling of data members and functions inside a single class. Bundling similar data members and functions inside a class also helps in data hiding. Encapsulation also ensures that objects are self-sufficient functioning pieces and can work independently.
- 3. What is Encapsulation? Encapsulation is one of the cornerstone concepts of OOP. The basic idea of Encapsulation is to wrap up both data and methods into one single unit. The way that data and methods are organized does not matter to the end-user. The user is only concerned about the right way to provide input and expects a correct output on the basis of the inputs provided.
- 4. Why do we need encapsulation in python? 1. Encapsulation provides well-defined, readable code 2. Prevents Accidental Modification or Deletion 3. Encapsulation provides security
- 5. Access Modifier in Python Encapsulation Sometimes there might be a need to restrict or limit access to certain variables or functions while programming. There we need an Access Modifier. 1. Public Member 2. Private Member 3. Protected Member
- 7. Encapsulation in Python using Public Members the public modifier allows variables and functions to be accessible from anywhere within the class and from any part of the program. All member variables have the access modifier as public by default.
- 8. Encapsulation in Python using Private Members The private access modifier allows member methods and variables to be accessed only within the class. To specify a private access modifier for a member, we make use of the double underscore __.
- 9. Encapsulation in Python Using Protected Members What sets protected members apart from private members is that they allow the members to be accessed within the class and allow them to be accessed by the sub-classes involved. In Python, we demonstrate a protected member by prefixing with an underscore _ before its name.
