Welcome to a foundational episode of the Salesforce Developer Masterclass, titled "Basics of OOPS Concepts & Apex Classes." This video is perfect for developers who are new to Salesforce or want to solidify their understanding of object-oriented programming (OOP) principles and how they apply to Apex, Salesforce’s powerful programming language.

Object-Oriented Programming (OOP) Basics:
We’ll start with a primer on the core concepts of OOP, which is a paradigm centered around objects rather than actions. Understanding these concepts is crucial for writing effective and maintainable Apex code. We will cover:

Classes and Objects: The building blocks of OOP. Classes define the blueprint for objects, and objects are instances of classes.
Inheritance: A mechanism for creating new classes based on existing ones, promoting code reusability and hierarchical classification.
Encapsulation: The practice of keeping fields within a class private, then providing access to them via public methods. This ensures the internal representation of an object is hidden from the outside.
Polymorphism: The ability for different classes to be treated as instances of the same class through inheritance, enhancing flexibility and integration.
Abstraction: The concept of hiding the complex implementation details and showing only the necessary features of an object.
Apex Classes:
Next, we’ll dive into how these OOP principles are implemented in Apex. We’ll discuss:

Defining Classes: How to create a class in Apex, including class structure and syntax.
Creating Objects: How to instantiate objects from classes and use them within your code.
Class Members: Understanding fields, methods, properties, and constructors in Apex classes.
Access Modifiers: Controlling the visibility of class members using public, private, protected, and global.
Inheritance in Apex: Extending classes to reuse code and create complex hierarchical structures.
Interfaces and Abstract Classes: Leveraging these advanced features to define common behaviors and create flexible code architectures.
Throughout the video, we’ll provide practical examples and best practices to illustrate these concepts. You’ll see how to apply OOP principles in real-world scenarios, making your Apex code more robust, reusable, and easier to maintain.

By the end of this session, you will have a solid understanding of the basics of OOP concepts and how to implement them in Apex classes, setting a strong foundation for your Salesforce development journey.
