<T>from a method which has a collection associated with it. However like any tool, it is up to the person using it not to hurt themselves (i.e. a screwdriver is not a hammer). In this example I have a couple of methods which do type safe conversion of a
Listof something. We need to know in advance what we expect that something to be. This is just one example of how you can do a conversion on a collection. I would like to note that there are methods on the
Collectionsclass which returns a checked collection. This ensures that any object added to a collection is of particular type. As the API notes, this is for the addition of classes after the collection has been turned into a checked collection. It does not check the Collection for previously added objects. The code below checks all of the object types before doing the conversion, and fails if it encounters the wrong type.
