Access Modifiers, Finals & Enums Access Modifiers Access Modifiers Access modifiers serve as guardians Regulating the accessibility of your code's elements. Encapsulation, Protecting sensitive data and ensuring controlled access to internal workings of your code. Data Integrity, and Preventing accidental or unauthorized modifications to critical information. Modular Design Creating well-defined boundaries between different parts of your program, promoting reusability and maintainability. Types of Access Modifiers Public Grants unrestricted access from any code within the same assembly or referencing assemblies. Private Restricts access to the same class or struct, shielding internal implementation details. Protected Allows access within the same class and derived classes. Coding Syntax Demo (Access Modifiers) Static Access Modifiers Defining how elements within: Class Struct Interface Interact with objects and instances. Static on Different Fields Static Class Cannot be instantiated, nor inherit/inherited Static Field Shared among all object, can be accessed using the class itself (No need to instantiate). Static Method It is not associated with an instance of the class. Constant and Enums Fields Final immutable values which are known at compile time and do not change for the life of the program. Enums It is a special "class" that represents a group of constants Final and Enums Structure Constants final = ; Enums enum { , } Coding Syntax Demo (static, final, Enums) Key Points The default access modifier for class members is private. Access modifiers apply to both members (fields, methods, etc.) and the class or struct itself. By effectively wielding access modifiers, you can craft: Secure Maintainable and well-organized code
