Can I use a class type parameter inside an annotation?

Think about the given scenario:

public @interface SomeThirdAnnotation {
    Class<? extends Something> value();
}

@SomeThirdAnnotation(T)
public abstract class MyClass<T extends Something> {
    // my code
}

Can this be possible in JAVA?

Is there any way to use a class type parameter inside annotations, because doing it will drastically remove code from the abstract class children.

Thank you very much for those who try to help me.

"Annotations cannot be generic or specify a throws clause. Annotations must return: an enum, primitive type or an annotation, String, or Class object. They can also return an array of these types." source: here
