== Using Generics == Once a generic class or function is defined, it can be instantiated or called with specific types. For example: ``` void main() { var intBox = Box<int>(42); var stringBox = Box<String>('Hello, World!'); print(intBox.getValue()); // Output: 42 print(stringBox.getValue()); // Output: Hello, World! } ``` In the above code snippet, two instances of the '''Box''' class are created: '''intBox''' with type ''int'' and '''stringBox''' with type ''String''. The generic type parameter is specified within angle brackets (\<\>) when creating the instances.
