Lesson: Classes and Inheritance

Generics

Generics allow you to define a class or interface once and instantiate it with a variety of types. A generic (also known as a parametrized type) is a type that has one or more type parameters. To use a generic you supply an actual type argument for each type parameter and in doing so constrain the generic type to act only on the argument types.
