Of course the correct implementation of these methods in the concrete class will ensure that everything works as expected. Obviously the interfaces do not allow you to perform any operation with them purely, you need the concrete type which in this case is List. Interfaces are used to generalize the type of a variable, parameter, or method return.

And this is important for harnessing code and making maintenance easier. Whenever possible, you should opt for the most general type possible through the interface. Note that all variables implement the List class. Learn more. Asked 10 years, 1 month ago.
