Object Oriented Programming (OOP) Part 1: Lecture 4

Object-Oriented Programming (OOP) Basics

• The purpose of OOP is to organize and structure code in a way that simulates real-world objects and systems.

Classes and Objects

• A class in OOP is a blueprint or template for creating objects.
• Classes define the properties and behaviors of objects.
• An object is an instance of a class, with its own set of attributes and methods.

Variables and Data Types

• Variables of Primitive Types store actual values.
• Variables of Reference Types store memory addresses or references to objects.

Class Attributes and Methods

• Attributes of a class are the data members that define the characteristics of an object.
• Setter() and getter() methods are used to modify and access the attributes of an object, respectively.

Object Creation and Reference

• Creating an object from a different class allows for code reuse and modularity.
• Reference variables and reference types are used to store and manipulate objects in OOP.

Static Members

• Static variables and constants are shared by all objects of a class.
• Static methods are used to perform operations that are not specific to any object.

Objects and Their Functions

• The primary function of an object is to represent and encapsulate data and behavior.
• Objects are created from a class template, which defines their attributes and methods.

Class Template

• A class template is used to structure and create objects with the same attributes and methods.

Data Storage

• The data stored inside a class is represented by its attributes or data members.

Getter() Method

• The primary purpose of the getter() method is to retrieve or access the values of an object's attributes.

Primitive vs. Reference Types

• The fundamental difference between variables of primitive types and reference types is in how they store and manage data.

Static Members

• The purpose of static variables and methods is to provide a shared resource for all objects of a class.
