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
