How to do `MyClass<String>.class` in Java?

How can call public <T> T doit(Class<T> clazz); using MyClass<String>.class as clazz where I can not instantiate or extend MyClass.

EDIT: 'David Winslow' and 'bmargulies' responses are correct (MyClass<String>) doit(MyClass.class); works for the original question BUT surprisingly when the method returns say MyClass<T> instead of T casting will not compile any more.

Edit: I have replaced List with MyClass and added the condition to my original question.
