Apex Variables & Keywords | Chapter 22 | Salesforce Developer Masterclass

Welcome to another informative episode of the Salesforce Developer Masterclass, titled "Apex Variables & Keywords." This video is designed for aspiring and experienced Salesforce developers who want to deepen their understanding of how to effectively use variables and keywords in Apex, Salesforce’s powerful programming language.
A solid grasp of variables and keywords is fundamental to writing efficient and maintainable Apex code. In this episode, we will cover the basics and advanced aspects of variables and the key keywords that are essential in Apex programming.
Apex Variables:
We’ll start with an introduction to variables, which are used to store data that your Apex code can manipulate. You'll learn about the different types of variables, including:
Primitive Data Types: Such as Integer, Double, Boolean, String, Date, Datetime, and Time.
Complex Data Types: Such as sObject types, collections (List, Set, Map), and user-defined types.
We'll explain how to declare, initialize, and use these variables within your Apex classes and methods. Through practical examples, you'll see how variables can be leveraged to store and process data dynamically within your applications.
Apex Keywords:
Next, we’ll dive into some of the most commonly used keywords in Apex, explaining their purposes and how they fit into your code. Key keywords we’ll cover include:
final: To declare constants whose values cannot be changed once initialized.
static: For defining class-level variables and methods that belong to the class itself rather than instances of the class.
transient: To declare variables that should not be serialized during Visualforce view state serialization.
this: To refer to the current instance of a class.
super: To invoke constructors and methods from a superclass.
By understanding these keywords, you’ll be able to write more efficient, readable, and maintainable Apex code.
This video will provide you with practical examples and best practices for using variables and keywords, helping you to avoid common pitfalls and to write robust Apex applications. By the end of this session, you’ll have a thorough understanding of how to use variables and keywords effectively in your Salesforce development projects.

Himanshu bhai, please can you plan a coverage on "private String varName {get; set};" as well. They are called getters & setters I think in apex. Also, I did not know that you can mention: public class2{ Boolean varName = new Class1.method1(); } public class AllMyVariables { public boolean isThisCorrect; public Account myAccRecord; private Date todaysDate = date.newInstance(2024,05,21); }

new Class1() is called instantiation, which you will understand better in the "static" keyword video which releases in a day or two.
