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
classfollowed 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.
