Understanding generics
Simply put, generics are types parametrized with other types. As we mentioned before, we can create a class, structure, interface, method, or delegate that accepts one or more data types they use as parameters. These parameters are known as type parameters and act as placeholders for the actual data types that are passed during compile time.
For example, we can create a class that models a list, which is a variable-length sequence of elements of the same type. Instead of having a different class that works with integers, doubles, strings, or any other user-defined types we might need, we can create a generic class that has a type parameter specifying the actual type of its elements. We will then specify the actual type at compile time when we instantiate the class.
Advantages of using generics include the following:
- Generics provide reusability: We can create a single version of the code and reuse it for different data types.
- Generics promote...
