how to maintain a list of static class and the instanciate from them

hello,

I have a list of uninstanciated class types and I wanted to call a static function from these































































"Class<? extends PropControl>" (without using reflection) that would create a new corresponding object instance































































but it appears I cant do that in java

so now I want to create a factory that takes a class type as aparameter to create the corresponding object instance

but this code dont compile:

Java Code:

public PropControl Create(Class<? extends PropControl> cls)
    {
        if(cls==HouseControl.class) <---- ERROR
        {
           here I create a new instance of HouseControl (that inherits PropControl)
        }
    }

I get this error :

incomparable types: Class<CAP#1> and Class<HouseControl>































































where CAP#1 is a fresh type-variable:































































CAP#1 extends PropControl from capture of ? extends PropControl

how do I achieve this ?

thanks
