Generic Class

What are generics?

Generics define type-safe classes without committing to any specific data types. They’re essentially a placeholder until a specified data type is declared. There are many prebuilt classes that use generics. This lesson covers how to create these generic classes.

Example: Generic class

Assume that the generic class in the next example is being instantiated with a string in the following way:
