Hi I am learning generics and I hope that this is not a silly question.

If I have an interface Foo<T>, having one method T getById(int id) whose implementation I defined in a file, which has two Java Classes. The implementation of Foo<T> is not public class but with default access scope.


In AnotherClass.java, I have


and


I have two questions,

1) When I try to use the statement



I get an error "Can not object of type User". I would like to to know why

2) When I try to use the implementation reference in AnotherClass, I have to specifically cast it .To show an example



which in turn throws a warning. is there a way by which I can remove the warnings and not suppress them.

Thanks for your help
