This document discusses abstraction and encapsulation in object-oriented programming. It defines abstraction as extracting only relevant information and gives an example of displaying a car without needing to know if insert or delete functions are available. Encapsulation is defined as an object's ability to hide data and behavior not necessary to its user. It provides examples of public and private access specifiers to restrict access to properties and methods. Access specifiers like public, private, protected and internal are also explained with examples.

The document compares C# and C++ programming languages, noting key differences such as C# being a higher-level managed language that uses just-in-time compilation and garbage collection while C++ is lower-level and compiles directly to assembly code. Some differences highlighted are that C# supports properties, delegates and events as class members while C++ only allows variables, functions, constructors and destructors, and C# has features like finally blocks and exceptions that must inherit from System.Exception that C++ lacks.

Java multi threadingRaja Sekhar

The document discusses Java's multithreading and multitasking capabilities, explaining the difference between the two concepts and the management of threads within Java applications. It covers thread creation methods, thread lifecycle, scheduling types, and priority levels, as well as daemon threads and the relationship between threads and garbage collection. Additionally, it highlights practical examples of implementing and using threads in Java programming.

Threads in JAVAHaldia Institute of Technology

Threads allow multiple tasks to run concurrently within a single Java program. A thread represents a separate path of execution and threads can be used to improve performance. There are two main ways to create threads: by extending the Thread class or implementing the Runnable interface. Threads transition between different states like new, runnable, running, blocked, and terminated. Synchronization is needed to prevent race conditions when multiple threads access shared resources simultaneously. Deadlocks can occur when threads wait for each other in a circular manner.

Pointers, virtual function and polymorphismlalithambiga kamaraj

Virtual functions allow objects of derived classes to be referenced by pointers or references to the base class. This allows polymorphic behavior where calling code does not need to know the exact derived class, but the correct overridden function for that derived class will be called at runtime. Some key points: - Virtual functions provide runtime polymorphism in C++. The correct function to call is determined by the actual object type, not the reference/pointer type. - Pure virtual functions are declared in a base class but provide no definition - derived classes must override these to be instantiable. - Constructors cannot be virtual but destructors can, and it is important to make base class destructors virtual to ensure proper cleanup

Lecture09a computer applicationsie1_dratifshahzadAtif Shahzad

This document contains a lecture summary on computer applications in industrial engineering. It discusses key concepts like classes, objects, fields, methods, encapsulation, properties, and constructors in C#. Classes define the structure and behavior of objects. Fields are member variables that define the data for an object. Methods define the actions objects can perform. Encapsulation involves restricting access to certain members to protect object data and behavior. Properties provide a mechanism to access private fields through accessors that can include custom logic. Constructors initialize new objects when they are created.

[OOP - Lec 08] Encapsulation (Information Hiding)Muhammad Hammad Waseem

Encapsulation refers to bundling together data and behaviors into a single unit called a class. The data and behaviors are inseparable. Encapsulation provides information hiding by separating the internal implementation details of an object from its external accessible properties and methods. This prevents unintended interactions and dependencies that could arise if all data was globally accessible. Access specifiers like public, private, and protected determine which data and methods are accessible from inside or outside the class. Encapsulation builds a protective barrier around data to keep it safe from accidental modification or access from outside the class.

Benefits of encapsulationMuhammad Nawzir Khan

Encapsulation promotes maintenance and code reusability by controlling access to data and code. It is implemented by defining public interfaces and keeping data and non-essential operations private. Object-oriented programming provides advantages like clear modular structure, easy maintenance and modification of existing code, and reusable code libraries. Key concepts of OOP include objects, classes, abstraction, encapsulation, inheritance, and polymorphism. Abstraction focuses on essential features while hiding background details, and encapsulation stores data and accessing functions together within a class.

Chapter2 Encapsulation (Java)Dyah Fajar Nur Rohmah

Encapsulation is a technique that makes fields in a class private and provides access to them via public methods. This prevents code outside the class from randomly accessing fields. Encapsulation combines data and behaviors in a class, and allows only behaviors to access and modify the data, controlling its values. It hides how an object works internally, making only its behaviors visible. Encapsulation draws boundaries around data and methods, allowing developers to use code without knowing how it works. It makes code more maintainable, flexible, and extensible by allowing updates without changing input/output formats.

The document discusses encapsulation and abstraction in object-oriented programming. It defines abstraction as denoting the essential characteristics of an object, and encapsulation as hiding non-essential details of an object. Encapsulation assists abstraction by providing information hiding. Access specifiers like public, private, and protected determine how other classes can access members. Static variables retain values between function calls, while static functions can only access static members. Friend functions and classes can directly access private members of other classes.

C# has public, private, and protected access modifiers that control the visibility of class members. Private members can only be accessed within the class, while public members can be accessed anywhere. 2. Properties are used to encapsulate private fields and provide controlled access via get and set methods. Automatic properties provide a shorthand syntax. 3. Encapsulation hides sensitive data by making fields private and providing public get/set properties. This increases security and flexibility. 4. Inheritance allows a derived class to inherit fields and methods from a base class using the ":" symbol. The

FME for Good: Integrating Multiple Data Sources with APIs to Support Local Ch...Safe Software

Have-a-skate-with-Bob (HASB-KC) is a local charity that holds two Hockey Tournaments every year to raise money in the fight against Pancreatic Cancer. The FME Form software is used to integrate and exchange data via API, between Google Forms, Google Sheets, Stripe payments, SmartWaiver, and the GoDaddy email marketing tools to build a grass-roots Customer Relationship Management (CRM) system for the charity. The CRM is used to communicate effectively and readily with the participants of the hockey events and most importantly the local area sponsors of the event. Communication consists of a BLOG used to inform participants of event details including, the ever-important team rosters. Funds raised by these events are used to support families in the local area to fight cancer and support PanCan research efforts to find a cure against this insidious disease. FME Form removes the tedium and error-prone manual ETL processes against these systems into 1 or 2 workbenches that put the data needed at the fingertips of the event organizers daily freeing them to work on outreach and marketing of the events in the community.

Enabling BIM / GIS integrations with Other Systems with FMESafe Software

Jacobs has successfully utilized FME to tackle the complexities of integrating diverse data sources in a confidential $1 billion campus improvement project. The project aimed to create a comprehensive digital twin by merging Building Information Modeling (BIM) data, Construction Operations Building Information Exchange (COBie) data, and various other data sources into a unified Geographic Information System (GIS) platform. The challenge lay in the disparate nature of these data sources, which were siloed and incompatible with each other, hindering efficient data management and decision-making processes. To address this, Jacobs leveraged FME to automate the extraction, transformation, and loading (ETL) of data between ArcGIS Indoors and IBM Maximo. This process ensured accurate transfer of maintainable asset and work order data, creating a comprehensive 2D and 3D representation of the campus for Facility Management. FME's server capabilities enabled real-time updates and synchronization between ArcGIS Indoors and Maximo, facilitating automatic updates of asset information and work orders. Additionally, Survey123 forms allowed field personnel to capture and submit data directly from their mobile devices, triggering FME workflows via webhooks for real-time data updates. This seamless integration has significantly enhanced data management, improved decision-making processes, and ensured data consistency across the project lifecycle.

Reducing Conflicts and Increasing Safety Along the Cycling Networks of East-F...Safe Software

In partnership with the Belgian Province of East-Flanders this project aimed to reduce conflicts and increase safety along a cycling route between the cities of Oudenaarde and Ghent. To achieve this goal, the current cycling network data needed some extra key information, including: Speed limits for segments, Access restrictions for different users (pedestrians, cyclists, motor vehicles, etc.), Priority rules at intersections. Using a 360° camera and GPS mounted on a measuring bicycle, we collected images of traffic signs and ground markings along the cycling lanes building up mobile mapping data. Image recognition technologies identified the road signs, creating a dataset with their locations and codes. The data processing entailed three FME workspaces. These included identifying valid intersections with other networks (e.g., roads, railways), creating a topological network between segments and intersections and linking road signs to segments and intersections based on proximity and orientation. Additional features, such as speed zones, inheritance of speed and access to neighbouring segments were also implemented to further enhance the data. The final results were visualized in ArcGIS, enabling analysis for the end users. The project provided them with key insights, including statistics on accessible road segments, speed limits, and intersection priorities. These will make the cycling paths more safe and uniform, by reducing conflicts between users.

Russia is one of the most aggressive nations when it comes to state coordinated cyberattacks — and Ukraine has been at the center of their crosshairs for 3 years. This report, provided the State Service of Special Communications and Information Protection of Ukraine contains an incredible amount of cybersecurity insights, showcasing the coordinated aggressive cyberwarfare campaigns of Russia against Ukraine. It brings to the forefront that understanding your adversary, especially an aggressive nation state, is important for cyber defense. Knowing their motivations, capabilities, and tactics becomes an advantage when allocating resources for maximum impact. Intelligence shows Russia is on a cyber rampage, leveraging FSB, SVR, and GRU resources to professionally target Ukraine’s critical infrastructures, military, and international diplomacy support efforts. The number of total incidents against Ukraine, originating from Russia, has steadily increased from 1350 in 2021 to 4315 in 2024, but the number of actual critical incidents has been managed down from a high of 1048 in 2022 to a mere 59 in 2024 — showcasing how the rapid detection and response to cyberattacks has been impacted by Ukraine’s improved cyber resilience. Even against a much larger adversary, Ukraine is showcasing outstanding cybersecurity, enabled by strong strategies and sound tactics.
