How to do `MyClass.class` in Java?

Question

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

Answer 1

Since after your update your question does not appear to be an exact duplicate:

You would need to call getClass() on an instance of MyClass. Better have a dummy static final instance somewhere:

public static final MyClass INSTANCE = new MyClass();
...
return (Class>) instance.getClass();
