Problem during dynamic casting (using reflection)

Question

Hi Guys,
Need you help
Situation is like this �.I have a function which accept the Sting parameter
Which is actually a full name of class �.using reflection I created the class and object
Now I want to cast this newly created object to their original class type
Code is somehow like this
Public void checkThis (String name) throws Exception{
Class c = Class.forName(name.trim());
Object o = c.newInstance();     
System.out.println(" class name = " + c.getName());
throw ()o; //// here I want to cast this object to their orginal class type
I tried throw (c.getName())o;
But it is not working
}

You can't cast to an unknown type like that. You're trying to throw the object, which makes me believe you're loading and instantiating some Exception or other, right? Just cast the result to something generic, like Exception, or RuntimeException, or maybe Throwable. As long as the class you load actually is a subclass of whichever you choose, you'll be fine. And if it isn't, you've got problems anyway because you can't throw anything that isn't Throwable
