Why can't I do the assignment at Line 1? a, which is of type <T extends A> can't be assigned to a variable of type A. why?

Thanks in advance for help.

EDIT After seeing Greg's reply: I added definition of class A.

I'm a little confused by your use of generics with a static, but I think the issue is you need to tell it what A is. So if you changed it to:



then it should work.

When I try that code the assignment works just fine. The return is the only line that fails to compile, and that's logical. T can be a subclass of A, it does not need to be A itself.
