In a nutshell, generics enable types (classes and interfaces) to be parameters when defining classes, interfaces and methods. Much like the more familiar formal parameters used in method declarations, type parameters provide a way for you to re-use the same code with different inputs. The ...
Introduction to Generics in Java By definition,generic programmingis a feature of programming language that allows methods or functions to work on generic types that will be specified later. The feature was fist introduced in Java byPhillip Walderin 1998 and later officially included as a component...
Another benefit is rich IntelliSense® support in Visual Studio® .NET as well as a clean debugging experience with generic code. In contrast, Java generics and C++ templates lose their generic identity by run time.Another benefit, and mainstay of the CLR, is cross-language use—a generic...
