    Object-Oriented Programming (OOP)

    A programming paradigm that organizes software design around data or objects, focusing on encapsulation over functions and logic.

    Objects

    Data fields with unique characteristics and behaviors representing real-world entities. In essence, they are the fundamental units of OOP.

    Declarative Programming

    A programming style where you specify what you want to achieve, not how to do it.

    Applications and Benefits of OOP

    OOP provides benefits like modularity, reusability, and maintainability, making it suitable for various program types.

    Study Notes

    Programming Models and Concepts

    • Object-oriented programming (OOP) organizes software design around data or objects, emphasizing encapsulation over functions and logic.
    • Objects are defined as data fields with unique attributes and behaviors, representing real-world entities.
    • Declarative programming involves stating what the task or desired outcome is, without specifying how to achieve it.

    Applications and Benefits of Object-Oriented Programming

    • OOP benefits various types of programs, particularly those requiring modularity, reusability, and maintainability.
    • Functional programming emphasizes function and logic modeling, contrasting with the object-centric focus of OOP.
    • The first step in OOP is the identification of objects that will be manipulated in the program.

    Programming Methods and Languages

    • Logic programming, which is primarily based on formal logic, utilizes languages such as Prolog.
    • Well-defined interfaces in OOP are known as APIs (Application Programming Interfaces).
    • Benefits of OOP include enhanced code reusability, scalability, and easier maintenance.
    • Functional and concurrent programming languages like Erlang and Scala are designed to facilitate these programming paradigms.
    • Compiled languages in OOP may be more complex to write and take longer to compile than interpreted languages.

    Specialized Programming Contexts

    • OOP is advantageous for building telecommunications and fault-tolerant systems due to its scalable design.
    • Each distinct sequence of logic in OOP is called a method or function.
    • Logic programming focuses on tasks that can benefit from rule-based logical queries.

    Object Manipulation and Relationships

    • The exercise of collecting objects and identifying their relationships is known as object modeling or analysis.
    • Notably, primitive data types are NOT considered foundational building blocks of OOP.

    Principles of Object-Oriented Programming

    • Encapsulation in OOP refers to bundling data and methods that operate on the data within a single unit or object.
    • Abstraction simplifies complex reality by modeling classes based on essential properties while hiding unnecessary details.
    • Inheritance allows classes to inherit properties and methods from parent classes, promoting code reusability.
    • Polymorphism lets objects be treated as instances of their parent class, allowing for methods to operate differently based on the object type.

    Programming Languages and Critiques

    • Ruby is often regarded as a pure object-oriented programming language.
    • Java is primarily object-oriented but also integrates some procedural programming aspects.
    • Python incorporates object-oriented principles but is not classified as a pure OOP language.
    • Benefits of OOP include increased program modularization and the ability to manage larger codebases effectively.
    • Criticisms of the OOP model often cite its complexity and potential for overhead in design and performance.
