T = data type. Insert the data type you need to use where the T is. Generics are all about the type-safe use of any data type (int, string, class, object, etc.) in a collection.

crap I forgot my old pwd

A generic works like this...Lets say I have an array of integers Array1<int>. If I try to add a string object to Array1, it will not let me. T is the type that the data structure can store.
