Access Modifiers - Global vs Public vs Private | Chapter 21 | Salesforce Developer Masterclass

Welcome to another crucial episode of the Salesforce Developer Masterclass, titled "Access Modifiers - global vs public vs private." This video is essential for Salesforce developers aiming to understand and utilize access modifiers in Apex to control the visibility and accessibility of their code effectively. Access modifiers in Apex define the scope of access for classes, methods, and variables. Understanding how to use them correctly is vital for writing secure, maintainable, and efficient code. In this episode, we will break down the three primary access modifiers in Apex: global, public, and private. Global: We’ll start with the global access modifier, which allows the widest level of access. A global class or method is accessible across all Apex code, both within your namespace and outside, including managed packages. We’ll discuss scenarios where using global is appropriate, such as when creating APIs or services intended for broad reuse. Public: Next, we’ll cover the public access modifier. Public classes and methods are accessible within your application or namespace but not outside of it. This is the default access level you will use when developing most internal application logic. We’ll explain when and why to use public, ensuring your code is accessible where needed while maintaining encapsulation. Private: Lastly, we’ll delve into the private access modifier, which restricts access to the defining class itself. This modifier is crucial for encapsulating code and protecting the internal state of objects from unintended interference. We’ll provide practical examples to illustrate how private can be used to maintain the integrity and security of your classes and methods. Throughout the video, we’ll provide practical examples and best practices for using each access modifier, helping you understand the implications of your choices and how to implement them effectively in your Salesforce development projects. By the end of this episode, you will have a comprehensive understanding of access modifiers in Apex and how to use them to control the visibility of your code components, ensuring your applications are robust, secure, and well-structured.
