Study Notes
Programming Paradigms
- There are two basic programming paradigms: Procedural and Object-Oriented Programming (OOP)
Object-Oriented Programming (OOP)
- Organizes data and functionality into objects, combining data and functionality
- Classes and objects are the two main aspects of OOP
Classes and Objects
- A class creates a new type, similar to creating a variable type (e.g., int)
- Objects are instances of a class, similar to how variables are instances of a type
- Variables that belong to an object or class are called fields
Object Functionality
- Objects can store data using fields (ordinary variables)
- Objects can have functionality using methods (functions that belong to the class)
- Methods belong to an object or class, differentiating them from standalone functions
Class Definition
- The
classkeyword is used to define a new class - Class definition format:
class :
Object Creation
- Multiple objects can be created from a single class definition
- Each object has its own set of attributes (fields) and methods
Constructors
- Class attributes can be initialized using constructors
- Constructors allow for initializing values when an object is created
