    Study Notes

    The Role of Classes in Programming

    • Classes are blueprints for creating objects.
    • They define the structure and behavior of objects.
    • Classes encapsulate data (attributes) and methods (functions) that operate on that data.
    • A class serves as a template for creating multiple objects of the same type.

    Creating Classes in Dart

    • Classes can be created directly in a main program file.
    • Classes can be created in separate files and imported into a main program file.
    • A class definition begins with the keyword class followed by the class name.

    The Purpose of an Object

    • An object is an instance of a class.
    • It represents a real-world entity, such as a person, car, or bank account.
    • Each object has its own unique set of data and behavior.

    The Ignition Point of a Dart Program

    • The starting point of any Dart program is the main() function.

    Why Objects in Object-Oriented Programming

    • Objects allow for code reusability and organization.
    • They help represent real-world entities in a program.
    • They provide a modular approach to programming.
    • Objects promote data hiding and encapsulation.
