Such as
Hashtable lvHT = new Hashtable();
Object obj = lvHT;
// Then how to automatically cast the obj back to Hashtable ?
If write code , I can cast it (Hashtable)obj , but how can it "automatically" cast back ?
Is there any way to do this ?

Downcasting (casting from super-type to a type lower in the hierarchy) will not be possible automatically. I don't think this automatic conversion is possible.

How would you use such an "automatical cast" at all? Can you give an example where you would like to use it?
