A simple example of generics is generic collections. Without generics, if you need a list filled with TPS Reports you basically have 2 choices: - Use the 'untyped' List that deals with objects. You will have to cast to TPS whenever you look up an item and you will have to make sure that no one accidentally adds a Timesheet to this list. - Write a custom TpsReportList. I'm sure you'll be able to write an implementation as efficient as the language creators. Oh an if you copy and past from TimesheetList, don't forget to check all names. `tpsReports.AddTimesheet()` is just embarrassing. With generics, you will have a `List<T>` type. If you need a list of TPS Reports you will use the type `List<TpsReport>`. If you need a list of Timesheets, you will use `List<Timesheet>`. You can't add the wrong type of item to such a list, you will always get the declared item from that list and you can't assign an instance of one type to a variable of the other type.
