Static Class
Static classes in programming are classes that cannot be instantiated and contain only static members, including static methods, properties, and fields. They are typically used to group related utility functions or constants that do not require instantiation of objects. Static classes provide a convenient way to organize and access common functionality without the need to create instances of the class, making them useful for scenarios where stateless, shared functionality is needed across the application. A common use case for static classes is in defining helper functions for tasks like mathematical calculations, string manipulation, or file operations.
